The magma vases have a glossy, white top and matte, cracked, white bottom. These are 2nd grade as they are glaze testers. The magma glaze usually has to crack on the bottom glaze, but it does not really do that here.
There are 2 of these.
Size Medium (height about 18 cm.)
The magma vases are on their way back in the range, and therefore the glaze is sometimes tested first. That way I can learn how it behaves in the burning with other vases, and optimize the glaze so that it looks the way I want.
