Chemically, most glasses are silicates. Fused silica by itself makes a good glass, but its high melting point (1723°C or 3133°F) and its high viscosity in the liquid state make it difficult to melt and work. To lower the melting temperature of silica to a more convenient level, soda is added in the form of sodium carbonate or nitrate but unfortunately the resulting glass has no chemical durability and is soluble even in water. To overcome this problem, lime, is added to the glass to form the basic soda-lime-silica glass composition which is used for the bulk of common glass articles, such as bottles and window glass. Although these are the main ingredients, commercial glass containg other oxides are used to make special kinds of glass. For example, boron oxide is added to silicate glass to make a low-thermal-expansion glass for glassware which must withstand rapid temperature changes (e.g. Pyrex glass). Also, lead oxide is used in optical glass because it gives a high index of refraction.

What is the first step to make stained glass?
If you mean the art form, the first thing you do is cut the glass. If you mean how to make the glass, you get the colored powder to make it. Unless you have the right equipment and etc, it can be deadly to make.
