Allow glasses to cool and if you take them out warm, lay 
them over a thick cloth as the contact with a cold body will 
split them at the bottom. 
To make matters more readily remembered, I will resume 
glass firing as follows: 
"Give your standing glass pieces a very flat flooring. 
Crooked flooring will give crooked glasses. 
Draw down your window shades and make the room dark. 
Do this every time you fire glass and you will always fire 
perfectly. 
When the kiln begins to show a little red, watch it. Your 
glasses look now dark, then middle dark, and when you can 
see through them, stop your fuel. Do not forget to open the 
door at once. 
Place delicate stem-ware in the very centre of the muffle 
(middle shelf) and thicker or low shaped pieces elsewhere. 
Gold and enamels require a trifle stronger firing than 
lustres and those pieces may be placed toward the back of 
the muffle or on the low shelf. 
Do not think glass firing is more difficult than china 
firing. It only requires a little more attention and method. 
Fire in the dark is my motto. 
Lest you forget, have the proper equipment. I have ex- 
perimented with almost everything, but found the glass muffle 
a necessity, a great economy in the end. It is a protection 
from the bottom and wall heat. It is clean, easily placed and 
taken out of the kiln. 
My next writing will be on enamels and perhaps on golds, 
all interesting and useful, but do not forget to master firing as 
this is the key to good success in glass decorating.
