The term stained glass can refer to coloured glass as a material or to works created from it.
As a material stained glass is glass that has been coloured by adding metallic salts during its manufacture. The coloured glass is crafted into stained glass windows in which small pieces of glass are arranged to form patterns or pictures, held together (traditionally) by strips of lead and supported by a rigid frame. Painted details and yellow stain are often used to enhance the design. The term stained glass is also applied to windows in which the colours have been painted onto the glass and then fused to the glass in a kiln.
During the late Medieval period, glass factories were set up where there was a ready supply of silica, the essential material for glass manufacture. Silica requires very high heat to become molten, something not all glass factories were able to achieve. Such materials as potash, soda, and lead can be added to lower the melting temperature. Other substances, such as lime, are added to rebuild the weakened network and make the glass more stable. Glass is coloured by adding metallic oxide powders or finely divided metals while it is in a molten state. Copper oxides produce green or bluish green, cobalt makes deep blue, and gold produces wine red and violet glass. Much modern red glass is produced using copper, which is less expensive than gold and gives a brighter, more vermilion shade of red.

The art of writing is one of the most important developments in human history and the Middle Ages were a period of slow but dramatic changes when it comes to this art and pursuit. In this article I will show you some of the types of writing of the Middle Ages and explain to you some of the changes that took place. While other developments through the middle ages such as art, painting, sculpture and music changed dramatically and rather quickly over the decades and centuries the art of writing did not! It changed very slowly over the course of centuries. Part of this is due to the fact that it in itself is a skill of conservation. Once a writing style or script had become popular it could become firmly entrenched and remain unchanged for centuries.
