There are a lot of high temperature porcelain and stoneware glazes 1280-1300 but little in them mid - temp. stone wear range .also some Raku/ soda and raw .... so general covers most areas....
majolica is well covered
seemed quite weighted towards reduction glazes in the high fired range,
but fails to cater for those with electric kilns who wish to fire at mid range stone wear
