Vinegar Etching (The Instructables Robot in Clay)

Using vinegar to etch and mend ceramics and pottery has been around for many years. I like this technique very much!

A potter named Benny showed this to me when I was only 12 years old, he used the vinegar to paint flowers on a dry, thrown vase, just by brushing the vinegar on, it would eat into the clay, and once the bubbled material was wiped away, you image was etched and ready to fire.

As you all know I love different mediums, and clay is definitely on my list. With its versatility, not to mention it's history, we all have been exposed, to it one time or another in our lives.

My 4H students really enjoyed doing this. Some did their names on tiles and made trivets and others created etched paintings on their hand thrown pots. This is by far one of the cleanest ways to remove clay,no dust or scrapings everywhere.

I love children their minds are so free.

Step 1: Tools & Supplies

Greenware plate (greenware is what clay objects are called before they are bisque fired).

Sign vinyl (for making mask)

Vinyl release tape

Vinegar

plastic container for vinegar

Paintbrush

A way to cut vinyl. (The Silhouette cameo was used for this project) Your local sign shop can make for you.

Image (used instructables robot) be careful with copyright.

Tweezers (helpful)

Paper towels

Water and bowl

Rub-n-buff metallic

Paint for finishing

Kiln or place to have piece fired.

Step 2: Cutting Design Mask

This step is only needed if you will be creating your own mask. The etching technique can be done freehand. I wanted to show just how, precise your design can be.

I first took the robot image and created a black and white live trace in Illustrator CS4. Then I saved it as a JPEG. With the Silhouette cameo design software, I opened the saved image. You can do tracing in the silhouette software but I use Illustrator.

After you open the image, you need to trace it to create the cut file, once the cut file has been created, send to the cutter.

The vinyl is silhouette brand.

Just a note: before I had a cutter, I went to my local sign shop, gave them my saved digital image and they cut vinyl, for me. I have used lots of auto decals with this technique, but remember the copyright. Ask them to not weed the vinyl, you want to do that yourself.

Now you have cut your image or had it cut, for this plate we need to use the negative part, this etching technique creates a void where the vinegar eats away at the clay body.

Moving on!

Step 3: Weeding and Transfering Image

With the vinyl cut you can now take the image and begin removing all the pieces you don't need.

Once the weeding is done, you will take release tape and cover your entire image. Remember you making a sticker mask to place on the plate. You can use an old gift card as a squeegee to adhere the tape well to the vinyl. Like in the pictures.

Prepare the greenware or clay piece; making sure it is dust free. Then start placing down the image ,working one side to the other , making sure to get good adhesion and no bubbles use the card or a backside of a spoon to rub down.

Please be careful your clay piece is fragile and will break if your not careful.

Very good the image is down; remove the release tape, slow, making sure vinyl sticks to plate.

Time to move on.

Step 4: Vinegar Etching Time

This step is really cool.

You should now have the image well in place. This next step should be taken slow in order to achieve the best detail..

Sometimes if you apply too much V, it can lift the vinyl, so do a little at a time, blotting with sponge and water. The water should be changed after you have blotted up the clay-vinegar after a few times. This will keep the design clean. Let the piece dry in between applications this keeps the V strong and from bleeding under the mask.

Refer to the pictures; you can see what you’re looking for. I do this about 4 times, it gives me a deep etch.

Let's roll!!

Step 5: Peeling Up the Mask

Take a needle, tweezers or your fingernail and begin taking up the vinyl mask. Careful not to gouge up the clay.

If some areas are not deep enough you can carve them out deeper. Remember this process is great for kids and adults.

Now you have reviled your design, with clean water and sponge blot the whole surface. (Don’t rub)

Fix what needs fixing, let dry.

Step 6: Fire It Up.

This really depends on you. If you have a kiln ,you know what to do.

So you don't have a kiln , well that's OK,the shop you got you greenware from, most likely does or can guide you in the right direction.

Once it has been fired to bisque.It is time to think about those finishing touches.

Step 7: Finishing Touches

The times they have a changed. Glazing was the finish of choice many years ago and for some nothing can compare. I have to say each project dictates to me what and how it will be finished.

Pottery glazes are so awesome, they can create beautiful one of a kind looks, but do require one or more firings and if you don't own a kiln, the cost can add up.

So here we go acrylic paints, oil paints, gilding.spray paint, you name it, just have fun and paint it.

Black light paints, metallics, I love them all.

There is this company called Alsa Corp they have a product called killer cans, WOW.

My next project I am going to try it and lots of other stuff, stay tuned.

Anyhow the plate I did was just based in a modern masters metallic paint and then black paint was used to antique with. That's just putting on black paint in the crevices and wiping of the surface. So the black stays down inside.

Then after it dries I took rub-n- buff and touched the high areas and edges with it, buffed it and we are done.

The other picture shows copper leaf, just another quick finish.

Hope you like!

Hey thanks for this! I want to try and make printmaking plates, etching them in this way..

[The Juliart]

Your Welcome! Let me know how it goes. I made textile printing plates and sprig molds before and it works great. Just keep the area wiped clean so the design stays crisp,in between vinegar washes.
Have a great day! J

Hi! Rod,
Basically I created patterns and turned into files called EPS for my vinyl cutter. After I cut the patterns out ,just like the Instructables Robot. Then took my clay tiles and created the plates. Fired them in the kiln and these were glazed white. The glaze will help keep tiles clean for future use. Then I made fiber reactive dye pastes, you can use plastisol inks etc. placed on my fabric and printed.
Similar to screen printing , but easier to clean and layer color ,just using a roller. The weight of the tile is nice and rigid.

I even used the same tiles and cast paper clay on them.

Hope that helps. It really comes down to details,do you hand carve the clay or use a computer to create patterns,cut vinyl,etch with vinegar.
Thank you! Julia

Textile printing plates? Wow Do you mean printing plates for textiles or printing plates made out of textiles? That sounds really interesting. Can you explain a little? Oh thanks a bunch.

Rod!

Well I thought your instructable was great and it got my vote! An inspiring project that stood out, keep them coming !

[The Juliart]

Hi! Thank you so much! It means a great deal. J

[The Juliart]

It would be nice to win tools,so you can keep creating insturctables. I can't even make it as a finalist with good instructables. Still love making and sharing.

[Pavithra Arunkumar]

This is awesome! Great instructable. I hope you win. Thanks for sharing :)

[The Juliart]

Hi! Sweet heart,Thank you so much. J

[jeanniel1]

I did this as a vinegar wash to make my surfaces bubbly when I worked on slip-cast pieces. It gave some really cool textures, and on my little houses, made the roof look like it had snow. I love that you didn't glaze it all over, and wiped stain to enhance the image on the plate! Good one!

[The Juliart]

So cool!! It is so great that Vinegar is so versatile. Thank you for sharing. J

[sunshiine]

I love what you did with the instructable robot. I haven't seen anyone do anything like this before. Thanks for sharing and have a great day~

Thank you Sunshine ! You to.
Keep in touch. J

[AnnabellaMarie]

Wow! What a great Instructable! I use vinegar for everything, but did not know it would etch. Guess what me and my great-grands will be doing next week!

[The Juliart]

What a great thing to say. I love that you not only like this Ible ,but that you will try with your family. That's what I love to hear. Thank you !
Please let me know how it goes. Yours truly! J

[The Juliart]

Thank you to everyone!!!

[BLASTFEMI]

I can hardly wait to try this! I had no idea vinegar etches clay! So many possibilities! Thanks for sharing!

[The Juliart]

I was surprised to learn that lots of people had never used vinegar in this way. I use it to fix and attach all so. You take your scrap clay pieces that are dry and grind to powder then add a little V ,to create a paste to mend with or just place a little V to both pieces and attach.
So glad you like it! Have a great day. J

[Victor Does]

I newer thought this where possible.. Thanks for sharing! :)
