What we liked
- + True Cone 10 porcelain, listed as translucent and firing white in oxidation and gray-white in reduction
- + Published specs include 0.3 percent average water absorption, the mark of a dense, vitrified body
- + Laguna is a long-established US clay maker, and the 25 lb bag is enough for a solid run of thrown pieces
Trade-offs
- - Average shrinkage is listed at 14.75 percent, high enough that pieces must be sized up and dried with care
- - Needs a kiln that reaches Cone 10, and it costs far more per pound than the stoneware-based options here
