silkscreening on clay

I have been silkscreening on both clay and glass. Under/overglaze straight
from the bottle (for clay) is what I have been using most recently and with
great success. This is screened onto either a raw or bisque surface. If
raw the pieces are then bisqued and if already bisqued the glaze is applied
and then fired to 1060 degrees C.

I have also used oxides and body stains with borax to lower the melting
temp. for screening onto glass but this mix will work equally as well on
clay. As I fire my glass pieces to 740C I work with a 50/50 ratio of oxide
or colourant to borax which is then mixed in a medium of oil or honey to a
workable consistency ( reached by trial and error). I have also used
this mix on clay.

I buy my screens ready made and coat them with Ulano 925 WR photosensitive
emulsion. I make photocopies of photographs, designs etc. and play with
them, enlarging or reducing until I am happy and then photocopy them onto
overheads for developing onto my screen. I mostly use only one overhead,
although I have been advised to use two but I have not found it necessary
to do so.

I am able to access a machine to develop my screens but am soon to try
developing them in sunlight.

Hope this is of some help
