Love it
Easier to work than white porcelain. Mixes really well with white porcelain marbling. Makes beautiful pieces.

Smooth black porcelain
Very beautiful and smooth black porcelain clay. I made a mask and it was gorgeous.

Laguna clay
Laguna porcelain cone 5/6 clay has an excellent texture. Easy to throw. Fires perfectly.

Food safe but Cracking Issues
Very pliable and workable. 100% food safe. Issues with it cracking during the “drying out phase” prior to the initial bisque firing, however. Tried Potter’s water to bind slab joints together but it proved difficult.
