I found a website [see below] with very good information. Here it is and I hope it helps you too. It explains more than stained glass cutting.
COMMENT:
Cutting of stained glass is almost a Zen experience. You have to know if the glass is warm enough, know the proper frying bacon sound that the scoring tool makes, and trust that when you flex with your thumbs that you won't sever anything important.
When it works it feels great. When it doesn't you are left with an oddly shaped piece of pricey waste glass.
The physical parts are:
Glass itself is made mostly from silica (sand), sodium oxide (from soda ash), calcium oxide (from limestone), and small amounts of minor ingredients. The minor ingredients give the glass its colour - for example a little bit of gold makes the glass red.
The liquid glass is poured onto a table of molten tin to cool and sliced into saleable pieces
As for turning the glass into a stained glass design, pieces are cut out of the sheets of glass and assembled into a pattern of various colors. The glass is held together by lead strips called "came" then soldered into a finished piece.
