KERAMIC STUDIO 
If it is a small design in rather fine lines it can be used on 
the glass without giving it any previous preparation. Where 
a good sized surface or very broad bands are to be done in 
Liquid Bright Gold, it is advisable to cover it with a sort 
of paste sizing that can be procured from dealers in glass 
supplies. Give this a light fire, it will shell off leaving a surface 
that will make the Liquid Bright Gold when applied and fired 
a richer, yellower color, almost like a Matt Gold. 
Acid etching may be done on glass, using the acid resist and 
the hydrofluoric acid just as we do the acid etching on china. 
When covered with rich Roman Gold it makes a beautiful border 
for goblets, or any other piece of glass where elaborate gold 
bands are effective. 
I have had letters of inquiry regarding designs for glass 
decoration. Most of my designs are original, but if you look 
through your Keramic Studio you will find many designs every 
month that will give you suggestions for glass designs. I now 
recall one of the very old Keramic Studios where there was a 
whole column of beautiful little borders, among them conven- 
tionalized ears of clover, thistle and nasturtiums; these were 
by Mrs. Robineau. They were very suitable for glass work. 
I have used many kinds of glass colors and glass gold. 
Glass colors will soon be on the market bottled in small vials 
like china colors. Meanwhile very satisfactory glass supplies 
are advertised in Keramic Studio. Teachers can procure them 
in bulk and bottle them to retail to pupils as I am doing. I 
consider firing the most difficult part of glass decorating, there- 
fore, will devote my entire time in my next article on glass 
firing.
