Let's face it, we all hate color chips! Particularly for glazes that are mottled or vary depending on thickness and such. Wouldn't it be better to see a whole piece covered in a glaze? I'm not sure why manufacturers don't offer this. So we are putting together our own Glaze Gallery. If you have any pieces glazed with one of the commercial glazes we sell, please take a digital photo and send it to us! Some people are doing wonderful things with layering of commercial glazes. Visit the Glaze Gallery

TIP/Project 60: Impressing Words With a Custom Rubber Stamp

This project comes from Kellie DeFries in San Diego, CA. She threw 50 plates for her wedding party, and used a rubber stamp to impress the lyrics to an old hank Williams Sr. Song.


I found these plates very impressive, so I asked Kellie how she made them.

Kellie: "I printed the text in a graphics program called: Freehand. Attached the text to a spiral line. Printed out a laser copy. Sent it to California Rubber Stamp Company. 4 hours and $85 bucks later, I have an AWESOME 8 inch by 8 inch rubber stamp. And I asked them NOT to mount on wood, to be more flexible with the clay, so it is just a piece of rubber stamp material. AND.... it is almost CLEAR, so I can see where to position the stamp in the base of my plate. Once it is placed on, I gently rub with my fingers until all has been smushed into the clay. Lift it off to reveal MAGIC!!

After the wet clay gets dry to the touch I press in the stamp. If it is tooo wet, it smears, if it is toooo dry, it won't press in all the way, and won't show up. Timing is everything in clay! ( I am a fan of the BLOW TORCH for these impatient moments of mine! )"

Then as a final touch, she used ink on the stamp to continue the design onto the packaging boxes.

A few other tips. She used a smooth clay with little grog, which is important to pick up the detail in the stamp. If the stamp got too wet she would simply rinse it off and let it dry. Because she needed a smooth surface on the plate, she used a translucent glaze. Translucent glaze is darker where it is thicker. So it is darker where it pools into the letters. For non-functional pieces you could use stain or glaze and wipe it off the surface, leaving it in the letters only.

Note: Type "custom rubber stamp" in a search engine and you will find many companies selling these types of stamps.

Kellie also made her invitations in clay!
