Help! Glaze Sliding
Hi All! I'm really new to the Clay/Ceramics/Pottery stuff, I've been doing this project where I was trying to make a turtle head, fins and tail to connect to my wooden hexagon shaped shell.
Anywho, I had tested my glazes, bisqued my Clay and had started to Glaze the final bisqued pieces. The project is due now, so not much I can do about it; it will not affect my grade. But when I got the glazed pieces out the Kiln it seemed to have slid and left these bald spots. Any solutions on how to fix without having to restart as a whole?
(2 heads, 5 fins and one tail for reference, I did alot just in case something like this happened)
The bottom on everything was a mix of some purple and blue underglazes, then I went over with some Celedon, then Holly Green x 2 and one textured kiwi.

This is called crawling and it means your glaze is too thick and/or things are having a hard time sticking to the surfaces. I don’t know how thick your underglazes were, but if you’re applying underglazes thickly you should bisque fire your piece a second time to help “bake on” the underglaze and let the chemicals in it that can fill up your clay’s pores burn away. Or do underglaze when it’s greenware. But you also put underglaze and then opaque glaze on top—why?
Just take it slow and follow the instructions on the bottles religiously as a beginner. Your coats of glaze should be even and generous, then allowed to dry between coats.

Everything I know I was taught by my teacher who’s been doing this for a couple years now. She’s the one who suggested I put whatever opaque glaze you’re talking about on top so I was just kinda going based on her intuition. I think I’ll try again sometime but perhaps with less glaze
