Query: a useful reference book of recipies

True, there is little here for cone 6 but the glazes I have tried out of this book are consistent and I have found many to be quite beautiful. I often use it for getting an idea of what properties generally need to go together to get a certain color or finish. I too wish something like this,(recipe type book) would come out for cone 6.
