Basisflglas

Basisflglas, also known as basis glass or basisflade, is a type of glass used in the production of stained glass windows. It is a thin, flat sheet of glass that is typically 3-6 mm thick. The term "basisflglas" is a Danish term, with "basis" meaning "base" and "flade" meaning "flat."

The glass is made by floating molten glass on a bed of molten tin. This process allows for the creation of large, flat sheets of glass with a smooth surface. The glass is then annealed, a process that involves heating and slowly cooling the glass to relieve internal stresses and improve its strength.

Basisflglas is used as the base layer in the construction of stained glass windows. It provides a stable, flat surface onto which colored glass pieces, known as fritt, can be applied. The fritt is cut to the desired shape and size, and then fired onto the basisflglas. This process can be repeated to create complex designs and patterns.

The use of basisflglas in stained glass windows has a long history, dating back to the Middle Ages. It was particularly popular in the Gothic period, when large, intricate windows were a common feature of cathedral architecture. Today, basisflglas continues to be used in the production of modern stained glass windows, both for religious and secular purposes.

The choice of basisflglas is important, as it can affect the overall appearance and durability of the stained glass window. Different types of glass, such as soda-lime glass or lead crystal glass, can be used, each with its own unique properties and characteristics. The thickness of the glass also plays a role, with thicker glass being more durable but also heavier and more expensive.
