      Moderators needed!   12/08/2017

      Ceramic Arts Network is looking for two new forum moderators for the Clay and Glaze Chemistry and Equipment Use and Repair sections of the Ceramic Arts Network Community Forum. We are looking for somebody who is an active participant (i.e. somebody who participates on a daily basis, or near daily) on the forum. Moderators must be willing to monitor the forum on a daily basis to remove spam, make sure members are adhering to the Forum Terms of Use, and make sure posts are in the appropriate categories. In addition to moderating their primary sections, Moderators must work as a team with other moderators to monitor the areas of the forum that do not have dedicated moderators (Educational Approaches and Resources, Aesthetic Approaches and Philosophy, etc.). Moderators must have a solid understanding of the area of the forum they are going to moderate (i.e. the Clay and Glaze Chemistry moderator must be somebody who mixes, tests, and has a decent understanding of materials). Moderators must be diplomatic communicators, be receptive to others’ ideas, and be able to see things from multiple perspectives. This is a volunteer position that comes with an honorary annual ICAN Gold membership. If you are interested, please send an email outlining your experience and qualifications to jharnetty@ceramics.org.

Can you remove wax resist from leather hard clay?

Recommended Posts

I have been playing around trying to figure out how stuff works and reacts etc. I brushed some wax resist on a leatherhard ( leaning towards the dryer end of leatherhard) piece of clay. I wanted to practice carving into it to make fine lines and such so I could brush thin underglaze into the grooves then bisque fire. It did not go well the wax just peeled right off when I tried gently carving a line through it. Since it wasn't working I decided to just scrap the whole square of wax off the clay and that got me to thinking... can you scrape wax resist off leather hard clay? I know you have to refire bisqueware to remove the wax but would kind of like to know if this also applies to unfired clay. I was able to remove all of the test patch I did, or at least it appears to be gone as I removed a thin layer of clay during the scraping and now the area is a dull gray once more and water did not bead up when I wiped it with a sponge. So is the wax gone or is it still lurking there somewhere?

The technique you were trying would work using wax resist on bisque, over a glaze and scratching the surface , then sponge on an oxide into the lines.

Wax on wet/leather hard clay will peel off as you describe.

To remove wax, fire the piece up to 500 degrees or a bit hotter to burn off the wax. Or just go ahead an bisque fire it.
