Lead, in the form of lead oxide, PbO, is added to glass to stabilize the matrix and improve the working characteristics of the glass. As a flux, PbO lowers the melting point considerably, and it also decreases the viscosity of the material. Additionally, lead oxide changes (increases) the refractive index of the glass.

Lead glass decanters, also known as crystal decanters, can be distinguished from regular glass decanters by their weight and clarity. Lead glass typically contains a higher percentage of lead oxide, making it heavier and giving it a brilliant sparkle and clarity that regular glass lacks. Additionally, the cut patterns on lead glass are often more intricate and defined. Looking for a “lead crystal” label or markings can also help identify lead glass decanters.
Lead glass is made with lead oxide PbO this makes it dense. It also has a higher refractive index than ordinary glass. It is sometimes called "lead crystal glass" and has been used to make cut glass ornaments and decanters. There is a lead poisoning risk from drinking wine that has been stored for long periods in lead crystal decanters.
No, however, newer stained glass utilized non-lead solder, and the lead (PbO, lead oxide) in leaded glass has been replaced more and more by the use of barium oxide, zinc oxide, or potassium oxide. While not banned, lead is used less often today, and the rare lead glass contains 24% PbO or near that amount. It is recommended that any glass suspected of containing PbO should be avoided with food or beverages.
The element that is found in both batteries and stained glass windows is lead. In batteries, specifically lead-acid batteries, lead is used in the electrodes. In stained glass, lead is often used as a component in the glass itself or in the framing to hold pieces together. Lead's unique properties contribute to the vibrant colors in stained glass and the efficiency of battery performance.

When a thermometer is put into the freezer, the sudden change in temperature causes the glass to contract rapidly, which can lead to the glass cracking or shattering. Glass is not very flexible, and extreme temperature changes can cause it to break.
which glass contains lead in it? Crystal glass has lead in it. more about types of glass here: http://www.britglass.org.uk/AboutGlass/TypesofGlass.html
Yes. It is the pottery you can’t eat from because it has a high content of lead. I wouldn’t put depression glass in the microwave though.

In the Townshend Acts, things like lead, paint, paper, glass, and tea were taxed. (The Revenue Act of 1767).
Lead can leach out of glass when the glassware has been treated or decorated with lead-based substances. However, most glass water pitchers do not contain lead and are safe for use with liquids. It is important to check the packaging or product information to ensure that the glass pitcher is lead-free.

Crystal glass contain lead.
Some glass has lead in it, specifically crystal glass. The lead acts as a flux in glass, allowing the grains of silica sand to be melted at a lower temperature. Glasses are generally denoted by their flux, so you get soda glass, flint glass, borosilicate glass, lead crystal etc. Lead also lends crystal the attribute of a high refractive index, making it a very clear glass and also soft. It can be easily cut with designs and polished. George Ravenscroft developed the first viable lead glass.
