Step 1: Find your frame

You have to have something to do your mosaic on, right? So the first step is to find a frame you like. For your first one, let's go with an 8"x10". Preferably wooden and not painted, and if it has any paint or fancy gilding it would be best if it has a protective coating of some kind. At some point you are going to be grouting and using glues, so it's best if the frame is sort of simple and easy to repair if something were to get scratched or scuffed. Hopefully your frame comes with glass, but if it does not, don't worry, the next step will cover getting that fixed.

Step 2: Making your backing

Picture of Making your backing
runningpliers.jpg
breakin.jpg
You are going to need to glue your mosaic onto something, and in this case we will be doing glass-on-glass. That means that light will show through your mosaic, but the back is going to be sort of ugly up close.

If you'd rather it be completely opaque, you will need to get a piece of fiberboard or some other hard, thin substance and cut it down to fit in the back of your frame.

If you are using clear or opaque glass that came with the frame, you are ready for the next step.

If you need to cut down a bigger piece of glass to fit into the frame, here is how you do it:

1. Measure your frame and jot down the size of the hole in the back that the backing glass needs to fill. It will be bigger than 8"x10" or whatever sized frame you are using, because the front of the frame is smaller than the back.

2. Procure your backing glass, whether it be old window glass, mirror, or opaque glass. If you are using window glass, don't use any with potential cracks (you can't always see them, so if the window has been broken in the past anticipate having invisible hairline cracks in the glass).

3. With a ruler (preferably a metal, cork-backed ruler to prevent skid), mark out on your glass with a sharpie where you need the cuts to be. If you have a square corner, use it and only make 2 cuts. If your corners all suck, put it about an inch in from the closest edges and make 4 cuts.

4. If you don't already have a glass cutter, get one. I like the fancier handled ones, but a simple oldschool cutter will work just as well. Get cutter oil as well, as cutting with a dry wheel tends to lead to chipping, breaks going askew, and horrible noises.

5. If this is the first time you have cut glass, make sure to read over the instructions that come on your glass cutter, if they came with any. Practice on a scrap piece first. Remember to oil your cutting wheel, and press firmly. Only cut in one direction, don't cut over another cut, cut your glass on a flat surface or table, cut on the smoother side of the glass if it has texture. Cutting away from yourself is usually easier than cutting toward yourself, although safety-wise in this case it doesn't actually matter.

6. Using the ruler as a guide, cut out your pane of glass. Set the cutter on the glass next to the ruler to see how close to the ruler it actually gets, and line up your cut accordingly. Your pane can be a little smaller than it should be, but if it's bigger it's not going to fit, and you'll have to grind it down. (We will not be going into grinding in this instructable.)

Oh, and be careful, glass is sharp; duh.

7. Once you have made your cuts, use a pair of running pliers to break the glass on your scores. They are curved, which puts stress on the glass and causes it to break on the score line that your cutter makes. Break the glass down and away, per the illustration I have provided. If you do not have running pliers and for some reason refuse to buy them or can't find them, you will need a straight edged table and some courage. Position the score just over the edge of the table, then lift and slam (gently) the glass downward. Carry on the motion beyond the table and grip firmly with your fingertips so that you don't drop the glass.

Step 3: Gluing your frame

Picture of Gluing your frame
wholeframe.jpg
Ok, you need to get a good craft glue, preferably something that dries clear and works on glass and wood. (And plastic or stone or whatever your frame is made of. A stone frame would be awesome. Heavy, but awesome.) You can use silicone for this step. I prefer using a silicone-like gel craft glue for this, but you could use a paste glue too.

I wouldn't recommend E6000 for this job, as it is light sensitive and will give out after a period of time hanging in your window. That would suck. Make sure your glue is not light sensitive.

Glue your glass into the back of your frame. It doesn't need to be a completely waterproof seal or anything, but you want it to STAY in there. I usually just put an even bead around the entire back. It will keep grout from bleeding through later, and makes it pretty darn sturdy.

Let your glue dry as long as it needs to. I usually let mine sit overnight.

Step 4: Okay, now the fun stuff starts

Picture of Okay, now the fun stuff starts
Find your subject! In the case of this instructable, it will be a portrait. If you need to go out and take a picture, do it. If you already have a pic, good. Take it into your favorite image editing software and crop it and resize to 8"x10".

To do a photorealistic mosaic, you would then just print it out, cut it out if necessary, and tape it into the back of your frame, like you were framing your template. I warn you now that I don't do photorealistic style because it is HARD. Really hard. you need tiny pieces, lots of colors, and more paitience than you would think or have. (Unless you do, in which case, damn you are dedicated.)

To do a stylized mosaic like mine, use a filter or hand draw over the photo using tracing paper. I use the "cutout" filter in photoshop and usually go with 2-4 layers depending on how many colors I want to use. Play around with it to see what you want to do, and it helps if you pick your theme of colors now. With mine I went with black/white/red and a little green.

Once you have your template finalized, print it and tape it into the back of your frame securely.

Step 5: Gather your palette

Picture of Gather your palette
Ok, now you're ready to start the fun/tedious part. Gather up the colored glass you want to use. Craft shops or specialty glass shops should have an ok selection, or you can order it online. Stay away from textured glass and cathedral (see-through or transparent) and streaky (partially transparent) glass and try to stick to smooth opaque glass, sometimes also referred to as opal or opalescent.

Once you have your glass, you need to cut it into tiles. I went with random shapes, but if you wanted you could do little squares or rectangles. I like the organic, angular look I get with my method, tho. Use your glass cutter to cut strips out. Make varying widths or if you feel comfortable with the cutter, do curvy strips so you can get lots of different widths. Once more, use your running pliers to break off the strips (you will need the pliers this time). If the strips are too thin you can try to break them with breaker/grozer pliers, but that can turn nasty quick.

Using your mosaic nippers (don't use tile nippers as they will crush the glass) chip pieces off of the strip into a little bowl or cup. You can angle the wheels differently to produce different shapes. You can just use your glass cutter to make the shapes too, but talk about a timekiller... Just get the glass nippers. They usually have little wheels on them to break the glass between them using pressure. You will be getting some hand exercise, be careful if you have carpal tunnel issues.

Step 6: Glue by numbers

Remember paint-by-numbers? It's just like that except with glass and glue.

My strategy is to pick a color to start with, and finish that color before I move on to the next one. If you are doing a much bigger mosaic (like a 16"x20" omg) you might want to go by sections instead.

Keep in mind that for an experienced mosaicker like me, it can still take like 6-8 hours to do a small mosaic portrait because of all the detail involved. Plan accordingly. I usually will set up in front of the TV with all my stuff on a tray or table and the mosaic on my lap, or on a desk or something. If you need to take breaks, do so. Just store your mosaic in a safe, flat place.

For your glue, you'll want a paste type glue, not a gel or silicone. I like omni-gel because it dries a little slow, so you have time to change your mind or move pieces around a little, and it drys clear and is waterproof. Weldbond is ok, but it dries a little quicker and the bottle seems constantly clogged. Even though it dries quicker, it takes longer to set and turn clear. But, it IS easier to find at the store. *sigh* Pick your fave glue and go for it. If you are unsure, do an experiment with scrap first.

I basically start in a corner or edge and work inward. I put a little pile of glue on a paper towel or aluminum foil and dab each piece in as I go.

****Another way to do it, which I have used and seen used successfully but find frustrating if something goes wrong, is to lay out all your pieces without gluing them down, then put a piece of contact paper on the top so that all the pieces stick to it. Put something flat and solid like a piece of glass or a book on top of the contact paper and use it to flip the whole thing upside down, then remove the frame and paint the glue on in a thin layer with a paintbrush. Then fit the glue-laden frame back onto the pieces and flip it back over. Pat and rub the contact paper so that the pieces are good and stuck, then wait for it to dry and peel the contact paper off.

The problem with that method is the pieces SHIFT BADLY for a couple reasons. The first usually being that it's practically impossible to get the contact paper down without them moving a little, and the second being that the contact paper is not sticky enough to hold the smallest of pieces, and they dislodge or fall off when flipped. So, it's an option, but I don't think it's the best option. Feel free to give it a shot if you want, I have seen people do it successfully, but there's a lot more after-the-fact fixing involved than I would like. ****

Remember to leave room in between each piece if you are planning on grouting. Techincally you don't have to grout it for it to be a mosaic, but I find that it gives the portrait a much more finished, smooth look, more professional.

Make sure that your mosaic dries well before you grout it. At least a day.

Step 7: Prepping the grout

Picture of Prepping the grout
paper.jpg
You don't need a special kind of grout for this and don't let anybody tell you that you do. You don't need to order DiamondCrete or fancy colors and stuff, but if you have the fancy-pants grout, feel free to use it. Just remember that DiamondCrete is really soupy because it's mainly for pouring into molds to make stepping stones, so if you are using it for this project, use much less water than they suggest in their directions.

Get ahold of some sanded grout from a garden supply store or craft store. I prefer black for most projects, but I have also used white, gray, pink, and slate blue. They make lots more colors, so get something that won't clash with your glass or frame. My shop used to buy the big bags from a grout supplier and separate them into 1 lb bags for a dollar a bag (ripoff!). If you buy a big bag and only use a little, just remember to store the grout in an airtight container for it's next use.

Don't get the grout down your drain, in your carpet, or on your clothes. IT WON'T COME OUT EASY. And it will clog the hell out of your sink. Put it in a disposable plastic bowl and mix it with a disposable plastic spoon, or if you want to use reusable stuff, take it outside when you are done and hose it off, and only use it for grouting, not for eating with. Mix it with just enough water to make it have the texture of moldable wet sand, not wet enough to be pourable or gloopy. Experiment a little, and add water a little bit at a time, stirring after each addition. You'll learn how much water you need with experience.

Make sure you have protected your home! If you need to grout indoors, lay down some newspaper or plastic sheeting. Always use gloves, grout color is heck to get off your hands.

Make sure you have protected your frame! Masking tape is the easiest way to do that. Cover ever inch of the frame that you don't want to turn the same color as your grout and get scratched to heck.

Step 8: Getting muddy

Grab a handful of your grout and smush it onto your mosaic. Keep smushing until every little nook and cranny is full of grout. Feel free to apply way more than you need. It will temporarily cover your mosaic and your art will look like a sandbox. It's okay!

Wait about 5 minutes for the grout to start drying. When you can wipe a paper towel across it and get it up enough to see the glass and not just smear around the grout, it's ready to clean off. Use dry paper towels, damp ones, a sponge, a rag, whatever you want. Just wipe off the grout and be careful not to peel up the masking tape. Make sure to get any lumps or buildup out of the corners, the grout tends to hide there.

Clean it off to your high standards (or low ones, whatever, it is your first one) and clean yourself up too. Once your artsy area is tidy, peel off the masking tape and chuck it. If there are any grout marks on the frame from sneaky grout that seeped under the tape, wipe them off with a damp towel. If they won't wipe, you can try some alcohol. If that doesn't work, retouch the frame with paint or markers. If that doesn't work, you'll need to repaint the frame most likely.

Then let it dry. Again, for about a day.

Step 9: Sealing

This step is optional. If you are using DiamondCrete you don't need to seal it, but if you are using standard commercial grout, feel free.

Get a grout sealant that dries clear. THAT IS IMPORTANT SO I'LL TYPE IT AGAIN. SEALANT THAT DRIES CLEAR. Many sealants add a sort of milky layer that will look like crap on your awesome mosaic. I can't remember the name of the one I use, but it comes in a bright yellow and green bottle and works like a charm. Follow the instructions on the bottle to seal. You'll usually want to apply 2 coats. It shouldn't do anything to your frame, but if you want to re-tape it, feel free.

Step 10: Hanging your art

Picture of Hanging your art
finished.jpg
PICT0106.jpg
You can use a standard tooth hanger to hang the piece, or eyehooks in the top of the frame, but avoid if at all possible using a "picture frame hanger" setup with one wire going across the back. It puts stress on the glass that could cause a fracture in the backing glass over time. See illustrations.

Ok, you're done! Congrats!

To spread the grout use half of an old pair of flipflops, no cuts, no bandaids.

How do i make the template?

KedaDibandion (author)  VERAL5 months ago
Good idea! As far as the template, I really just played around in PhotoShop until I got something I liked. You could use crazy filters on phone apps, or Gimp as well (a free image software).
mouly5 years ago
I have started working on this. I'm around Step 5 - having trouble finding the colored glass online. Most of the online stores sell assorted colors - so I can't pick the exact color I want. Do you have suggestions (links) to the products I could try?
crapsoup mouly11 months ago

If you mix elmer's glue with food coloring, cover pieces of glass and bake on low temp in the oven for about an hour, you can make any color glass you want. ( just remember to place the glass in the oven before you heat it and let it cool before you remove it.

eka1 crapsoup6 months ago
Hi, thanks for the tip!! Can I apply the same tactic to make colored tiles?
pjstewart mouly5 years ago
Since you can't find colored glass to match, have fun with it.  Remember, cool colors (greens, blues, purples) recede, and warm colors (yellow, orange, reds) advance.  Remember, stained glass portraits do not look like real portraits anyway; colors will make it look interesting. 
KedaDibandion (author)  mouly5 years ago
http://www.delphiglass.com/ is a good resource for glass and supplies.
http://www.spectrumglass.com/stained-glass/retailers/ -- you can also do a search here and see if anyone sells spectrum (easy & cheap glass) near you.

Big thanks for this. The filter tip will save a lot of time. Photoshop C6 requires you to "convert for smart filter" before you can use the "Cut out" filter.

Ty I can't wait to give it a try!!!
Hello,

Congrats for you comprehensive instructions, they are great. I want to start making mosaic table tops and realize for that kind of object is quite important to get a very flat surface, how could I achieve it? Could you make an Instructional about it? I have lots of questions.

Best regards.
KedaDibandion (author)  estebansensei3 years ago
Are you planning to use tempered glass tabletops, or wood, or something else? I have a tabletop project I have been thinking of doing -- I purchased a custom-made iron table built with angle iron for the framing of the top so that it will hold a piece of plywood to use as a mosaic substrate.

One way to achieve a level tabletop after a mosaic has been laid down would be to cover it with a clear resin (applied as a liquid) so that the surface sets level. I have not tried this, but I have seen it done, and it seems like it would be particularly useful as a table surface because it would be easy to wipe clean.

Beautiful.
This is amazing. Thanks for sharing.
Q. i would like to do a mosaic on my bathroom door (of a mermaid of course! i have two sons so it will be a merboy and his sealPUP). can i glue directly to hollow core door? Q. can i get away with mounting door and working on mosaic a little at a time or does it def. have to be in horizontal position? might this depend on finding glue wit shortest set up time? thanks!
i am hoping to make mural full size, therefore i thought that i would use regular bull nose tile as a frame around mural. i thought that would be in keeping with project but make safe edges. what to do you think? Q. good point about the wood since it will be in a bathroom! what do you mean by sealing the wood? do you mean like boat varnish? i like suggestions about tape/contact paper as i would only do small sections at a time. thanks for answering so promptly.
KedaDibandion (author)  misskitty9145 years ago
Bull nose tile should work, just make sure that the extra width on the door won't interfere with the hinge mechanism. As far as sealant, something simple like polyurethane or like a deck sealer should work ok.
yeah, i think i'm going to do the hardware work first (hinges and doorknob). thanks for all of your input!
KedaDibandion (author)  misskitty9145 years ago
You should be able to glue directly to the door. Keep in mind that there will be edges, so if you are not going to mosaic the entire door think about creating a "panel" with wooden edging of some sort to isolate/protect the mosaic on the door. As far as doing the mosaic upright, I'd do a test first with a couple different glues and see how much they slide before drying. You could also use contact paper (preferably clear so you can see your pieces) after gluing for a while to sort of hold up the pieces while they glue. Tape could do that too. Keep in mind that the mosaic will be subject to jarring due to the constant opening and closing of the door, and humidity. It might be a good idea to seal the door if it isn't already, so that the expanding and contracting wood doesn't affect the mosaic as much.
adarii5 years ago
Hiya, this is a great instructable I'd love to try. I was wondering if you could maybe add exactly how you convert your photo to the template you end up using for your mosaics. I know you mention using the "Cutout" feature with Photoshop but after fiddling with that I wasn't able to come anywhere near how your photo came out. Are you using other steps as well? Thanks!
KedaDibandion (author)  adarii5 years ago
I can't get to my computer with adobe on it (silly virus attack) but from memory.... First I'd resize it to the correct size for the frame I was using, usually just 150-200 dpi resolution. (The template doesn't have to be super crisp, and usually the filters have a better effect at this resolution.) Then I'd go to Hue/Sat and "colorize" the image to the general selection of colors that I want. From there, I'd go to cutout and fiddle with the settings there until I have something I like. Does that help?
Thanks, that helped a lot. I filddled around some more after your tips and got some good results.
MaxineLaRue6 years ago

Your mosaics are so pretty! Making one for my sister.... I hope it comes out nearly as good!

Send me a picture when you're done!
i used to make something like this using shrink-it paper...trace and colour the photo,then cut it up into small pieces...looked really good when i scanned and printed a portrait and made it grey scaled.like an old b&w pic..love this mosaic one..ill definatly try iy if i ever get brave enuff...glass scares me lol.
KedaDibandion (author)  teachme2night6 years ago
Glass is awesome, you just have to be careful, treat it with the respect it deserves, and not be too squeamish; you WILL get cut as a glass newbie. It just happens. The good thing is, the glass that cuts you is usually so sharp you don't even know you're cut until you see blood on what you're working on! Ah, silver lining.
shazni6 years ago
this is really nice....for people who cant find coloured glass or tiles...or if it's very expensive like in my country...or sometimes if we are lazy... paste a photogragh...and then paste clear cut glass on top. then do the same grout stuff. and Bang!!! you have almost the same effect!
jtong776 years ago
Great ible!!! So beautiful and accessible. I have a question: why does the glass need o be glued to the frame? Is it because using the original backing will block light from going through? If that's the case, do you think it may work well to make a custom backing with plexiglass to utilize the original tabs in the back to hold the mosaic in place? That may save some glue drying time.
KedaDibandion (author)  jtong776 years ago
Mostly it's so the mosaic doesn't shift in the frame once it's grouted and crack the grout. I would at least put a couple spots of glue, or just do the corners.
aholway6 years ago
REALLY looking forward to trying this--I'm just getting into mosaics--so THANKS! Question, tho: any particular reasons to do this within a frame rather than setting frame around it when it's done?
KedaDibandion (author)  aholway6 years ago
I'm not sure what you mean by 'setting frame around it when it's done," could you elaborate?
I think the question is... can you just craft the mosaic on the glass backing, without the backing being seated in the frame during construction, and then slide the glass backing into the frame after the mosaic is completed? I'm assuming you can't do it that way because you might get the mosaic into areas of glass which are supposed to be fitted into the frame, and then you will cry great big soppy tears that you wasted all that time sizing the glass to the frame... This is so awesome and I'm now looking at a hobby in which I was never interested until I saw your 'ible. Thank you for sharing!
KedaDibandion (author)  Sooz6 years ago
Ah, I see, yeah. I like to have the frame already there so that I don't do that exact thing. I want the glass to get really close to the edge, and the easiest way to achieve that is to have the frame there to butt the pieces up against.
neale6 years ago
brilliant!!! i am so excited to try
