Introduction: How to Make Glow in the Dark Glass

SIMPLY WATCH A VIDEO...

OR SEE FULL INSTRUCTIONS BELOW...

Hi guys,

In this tutorial you will learn how to make glow in the dark glass / glasses my way! They are awesome and glow beautifully in the dark! I actually came up with this idea about a year and a half ago or so during one of my creative moments :-) I just thought it would be super entertaining to bring them to parties and have drinks with my friends.. and they were really impressed! Everyone loves them! :-)

OK, let's get started!

Step 1: You Will Need...

Crystal resin (I used Gedeo Crystal resin)- bought on Amazon

rubber gloves

stirring sticks

mixing cups - from Ebay

glow in the dark pigment powder - I bought this a while ago from Ebay and the powders I used were cyan and green. I found the green one was more intensive and bright.

(I have used about a tablespoon of the glow in the dark powder to 40ml of resin)

kitchen towels

glasses or clear plastic cups of your choice (with at least slightly inverted dome on the bottom)

rubbing alcohol/ soapy water

something to protect your surface when working with resin, I just used a piece of cardboard

Step 2: Clean Your Glass

Clean the bottom of your glass with some rubbing alcohol or just wash them in soapy water to get rid of any grease and dust.

Make sure it's completely dry before the next step, resin does not like water!

Step 3: Mix Your Resin

Mix your resin according to packet instructions and once it is crystal clear, add the glow in the dark powder and mix thoroughly.

Always make sure the area where you work with resin is well ventilated and also protect your hands and eyes if possible.

Step 4: Pour Resin and Let Dry + a Tip!

Turn your glass upside down and apply the resin mixture. Make sure it doesn't create a dome, it needs to be flat - unless you want a wobbly glass :)

(Only use the resin on the reverse side of the glass, so that it doesn't come in contact with food or drink that you will then consume. I would also advise to hand wash separately from other dishes in warm but not hot water)

Let it dry for a couple of days in a warm - room temperature(resin doesn't like cold either!), dry and dust free environment.

Tip: To make the glass glow even more, use a UV light/ torch and point the light at the dried resin on the bottom of the glass - do this for at least 10-20 seconds. The glass will glow really intensively within seconds!. Or you can just take an advantage of the sun! The longer you leave it ‘charge’ in the sun the longer it will last and glow more intensively.

Step 5: Finished Glasses

Aren't they cool?! :)

These are great! Such a beautiful effect. I make a lot of things that glow with LEDs el wire etc, but I always forget that there are simpler ways to create awesome glowing effects that don't require electricity! I'll have to try a project with this technique. Also your photos are lovely :)

Such a great idea! Two things though.

1. Would you consider those very dishwasher-safe? I'm not a chemist and I don't know if and how temperature and steam would affect the bond between resin and glass.

2. This is more of a suggestion related to point 1. Before rubbing the glass with alcohol, I'd apply some fine grit sandpaper and elbow grease to the bottom of the glass to roughen the surface up a bit. The bond will be stronger this way. ;)

Hi there, I would hand wash only in warm but not hot water. The 2nd point is a good idea, I actually though of it after I've posted this tutorial too :) I'm sure it would hold the resin even better! :)

Oh yea, my next project is to get that glow in the dark spray paint for my flower pots!!!

author

sounds like a good idea!

sillescas (author)2016-05-12

I added the green to clear nail polish and painted along the top edge of our floor molding. This way I can see easily to get down the hallway without lights to the bathroom. I also painted the light switches and a thin outline on the wood around the door handles. Oh yea, I painted the edges of the bed posts at the bottom because we keep smashing our shins on them. As well as the back side of my bedside table pull knob. I guess I kind of went a little crazy but things sure are easier now! It works really well as long as it receives sufficient light to "charge" to glow.

hahaha great! Sounds like a glow in the dark house!

Found this very interesting!!!! I raise chickens and you have given me the inspiration to tackle a lighting problem in my coops. At night I like to check one last time that things are okay. If I turn the lights on the noise is defining. Using a flashlight takes longer and it still causes stress on the chickens. I'm going to go to the second hand store buy clear glass "anything" and make it!! Then position it so sunlight hits is daily. I'll test it and let you know. THANK YOU

Why don't you try the idea of making a small hole in the roof and epoxy/silicone in a clear bottle containing a little water? Then add some of this to the bottom. I've read that a small drink bottle equals a 60w bulb!

I went on a Berlin Underworld tour of a civilian bomb shelter, there was one room for the volunteer firefighters where the walls were painted with glow in the dark paint. You can hardly see it now, but according to the tour guide, back then it was supposedly bright enough to read by for an hour or so after the electricity went out.

author

Wow - thanks for telling me.

author

Cool, yea that could work, let me know please :)

This is just lovely.. Thnx for sharing

You could also just mix the glow powder with clear nail polish. It may not be as hard as resin but it shouldn't get much wear and tear on a concave surface.

author
TeresaM7 (author)xenobiologista2016-05-09

Probably a whole lot more expensive, too. Still, you could use it to paint designs up the sides of the glass. That might be fun.

author

Hi there thanks for all your comments! You could definitely use just nail polish, but as you said it's not very hard. I would always advise to put the mixture from the other side of the glass, not just because of the powder but the resin as well.

I guess you never hear about vaseline glass or uranium glass ...

They are available at flea markets and antique shops.

author
xenobiologista (author)EmilA12016-05-08

Vaseline glass does not glow in the dark by itself, it's fluorescent under UV light.

Also uranium is a heavy metal, even the non-radioactive stuff is kinda toxic. Probably not good for drinking glasses.

That looks really cool! Thanks for sharing!

author

Thank you :)

Catley (author)2016-05-08

This is really special! Makes me wish I drank, but would be a good present for friends who do, and there must be other things that could use some glow in the dark resin!

author
HelenaDaydreamer (author)Catley2016-05-08

Oh you can sure drink just water from these - nobody will find out! ;)

author
MTKapp27 (author)2016-05-06

Really cool. I can't wait to surprise my wife.

Why does the bottom need a slightly curved shape??? I don't understand why any shape would not work, because the resin should hold in any shape.

author

All explained by Catley :))

author
Catley (author)MTKapp272016-05-08

I also think that any shape would work, provided the resin can get into it. She probably just intended to make sure that there was a depression of some sort for the resin to rest in; there *is* that expression "at least an inverted dome."

I was the opposite of you: Not having checked the list of things needed, I found myself wondering if we were supposed to just make a thin layer of resin on the bottom of the glass, which I do sometimes when making jewelry. But then I went back and read it (sheepish face).

author
HelenaDaydreamer (author)Catley2016-05-08

Thanks for the explanation, that's exactly what I meant :)

Hi:

Just wondering what this material is that will glow in the dark after exposure to daylight? Strontium Aluminate?

author

Hi Jaudette, do you mean phosphor?

FatimahK (author)2016-05-07

Hi there . i'm just wandering , instead of glass cup.. Can i change it to the other cup instead? like a polystyrene cup?

author

Hi, If you mean a clear plastic cup, then absolutely! I have done it with plastic shot and wine glasses and it looks just as good! Those are shown on some of the pictures :-)

author
John T MacF Mood (author)2016-05-06

I wonder if you were to etch (either chemically or with sandblasting - I do both depending on the area to etch. - chemical etch only works well in small areas.)

Would the glow from the bottom of them light up your etching? I think some experimenting might be in order! Thanks for the inspiration!

author

Hi John, I was wandering the same! :) That was kinda my next project, so I will let you know- unless you attempt to do it first and in that case please let me know :)))

author

Deal, it's a race! ;-)

I should try this for a walk way in the yard

These came out so beautifully! Super inspirational - thanks for sharing!

author

Thank you very much Audrey!

Heyup (author)2016-05-06

Great ible Helena, how long does it last for? :)

author
HelenaDaydreamer (author)Heyup2016-05-06

Hi Heyup :) If charged ideally in the sunlight they will last all night! The intensity of the glow will go eventually later on in the night, but the will keep glowing.

author
DebbieCotter (author)2016-05-06

Hey Helen! LOVE this idea! How long would you say the glasses stay glowing? Also, would I need to "charge" them under a bright light or sunlight for them to glow? Thanks again!

author

Hi Debbie, the need to be at least left in the daylight, in your room or outside in order for them to glow later, but if the sun is out and you leave them charge in the direct sun then they will be a lot more intensive and should last all night. Maybe not as intensively as at the beginning, but you can always top them up with the UV torch! :)

WOW - Did I pick the right day to treat myself to an hour of Instructables perusal! This particular Instructable is ingenious and amazing; and by the looks of your other links and resources, so are you. (Now if I could only remember what it was the other day that I was wondering if I could make glow in the dark...)

author
