Whatever you do, do not throw this glass away. You have what is known as “float glass” and it is identified by the wavy distortions and other defects such as pitting. It was largely replaced by plate glass starting in the 1940′s, and has all but disappeared since the advent of replacement windows. It is also used by furniture makers and refinishers to replace the glass in antique china cabinets, barristers bookcases, and the like.

This glass is highly sought after by home restoration contractors doing business in designated historical districts where the glass is still considered “period” and mandated by regulations.

Every big city has at least one architectural salvage business that will be interested in buying your glass. Other places to check are antique dealers (they will want you to pay them to take it off of your hands), architects specializing in restoration projects, and contractors who do the same. Your local historical society may also offer some leads as to where you might sell it.

In the meantime, leave it in the sash frames so it doesn’t get damaged.

Good luck with your salvage project.

If you have an architectural salvage store in your area you might check with them. Shame to just throw them out!
