hard-packed and baked but not solid or rock-like sand. I used fireclay,
play sand and water only, exactly as the book describes.
After re-reading the Gingery section on curing the refractory, it seems
there might be another interpretation. It sounds like maybe "curing"
only drives out the water and then "vitrifying" makes it really solid.
Is that true? Or should I have essentially a millstone when I take it
out of the oven?
Pictures here, the last two items are mainly about the lid.
