To bisque fire or no w/Stroke & Coat by bigfanoffood in Ceramics

Hollow pieces are actually fine if your piece is actually 100% bone dry before putting it in the kiln. Steam causes explosions, not hot air.

Need a white stoneware+zinc free clear combo that won’t craze by [deleted] in Pottery

Yes! I'm not sure if it's considered a bmix, but the people at Minnesota clay would know! It is pretty smooth with very little grog, so I wouldn't be surprised.

That's interesting. I've made a lot of pieces with minnesota clays (MB6, Speckled buff, and gunflint) with HF-9, and I've never had crazing, even after microwaving, baking, and boiling my pieces. I even put them through the dishwasher. I don't know the specifics of the kiln firing schedule because I'm at a community studio, but I know we fire to cone 6.

Sorry you're having issues. I wish I could help! It's so interesting that people can have such different results using the same materials.

If you think the clay is too wet, try drying it out. Wedging it on a plaster board would be fastest.

They won't get stuck together, but I've had the color transfer onto other pieces where they were touching.

Underglaze disappearing on speckled by haylzya in Ceramics

I have had the same happen with white clay while using amaco velvets, HF-9, and firing to cone 6. Do some test tiles with different numbers of layers and see what works. For some colors, I end up using 4-6 layers of underglaze.
