Dear Friends,
Building up an materials inventory is something we all have to face up =
to if we are determined to be independent of ready made glazes or rely =
on what clubs, schools and other pottery groups provide.
What is purchased will depend on personal aims and objectives. So make a =
list of your goals and devise a list of materials which will enable you =
to achieve them.
Given the aims that I would not imitate anyone or use a ready made =
recipe I could get by with four basic recipe items, a felspar, an =
auxiliary from the group two elements, silica and a clay. From these I =
could achieve about four hundred bases which would vary from transparent =
to opaque. If I wanted to work at a lower cone level I would add one of =
the Borosilicate Frits and have a look for good constant ratio blends =
giving the degree of melting and fluidity I might need which would arise =
form blending that with the felspar.
Then I would select from the eight Metallic colorants, choosing =
carbonates where they are available. Using these alone and in pairs =
gives at least forty four samples which will give an introduction to the =
spectrum.
To extend further I might throw in some Ash and Rock powder .
Glazing...As simple or as complex as you choose to make it.
Best regards,
Ivor Lewis

what is an auxilliary from the group two elements? perhaps whiting, for
example? or neph sy and 'wolly'? -brian
