Why it worked

The video effectively answers a common question about ceramic glazing techniques, providing a clear visual demonstration and explanation that is both informative and satisfying for viewers interested in pottery.

Summary

The video demonstrates a ceramic glazing technique where a portion of the piece is left unglazed to prevent it from fusing to another part during firing. The creator explains that this method works because the glazes used are stable and do not run excessively when fired.

How does the middle glaze not spread and it fires while becoming sealed inside? So cool 🔥🔥 Reply to mcmiller4ever Here's the secret: unglazed

Original caption

The ceramic surfaces that touch are sponged clean of glaze so the lid and tray portions don’t permanently fuse together in the kiln 🔥 The glazes we use are very stable, meaning they don’t run much during firing. This technique would not work with a super runny glaze.
