GLASS COLOURING HISTORY THEN AND NOW

Around 3500 BC, the first real glass was produced in Mesopotamia and ancient Egypt. Some of the first coloured glass objects were beads and small jars. These early glassmakers discovered that adding different substances to the melt would change the resulting colour. Once methods of making coloured glass were discovered, an explosion of experimentation began. The aim was to find substances that would produce specific colours in the glass.

In the eighth century, the Persian chemist Abu Musa Jabir ibn Hayyan, often known simply as ‘Geber’, recorded dozens of recipes for making glass of specific colours. Geber is often referred to as the “father of chemistry”, due to his recognition that metal oxides were a key ingredient for colouring glass.

Today each glassworks has its own traditions and its own secret recipes for creating a range of colours. So don’t expect exact recipes for specific shades, each glassmaker guards the exact recipes like an eye in the head. What we can reveal to you, however, is the dyeing process. And there are curiosities, such as the use of uranium oxide or the use of cow poop to dye glass.

Process goes like: The natural colour of the glass is greenish. It must be de-coloured. For this, sodium nitrate or manganese dioxide is used. Once the colourless mixture is ready – which is the standard – it is ready to start.

Mix the solids

Although the following description may seem simple, it is definitely not. Painting glass is a precise job, so it is important to measure, prepare and plan everything carefully. The metal oxides used to colour glass are stored in bulk form. These oxides are added directly to the bulk mixture of the glass strain and everything goes into the mixer. The mixture must be absolutely homogeneous, so no expense is spared in mixing.

Put it in the pan

The perfectly homogenous mixture is then loaded into a huge melting pan and melted until it forms the melt that is formed into the crystal products as we know them.

It must be accurate

Each time the colour is mixed in, the shade must be tweaked to match one hundred percent. With the finest glassworks, it is not possible for individual batches of coloured melt with the same name to vary by even half a shade. Therefore, each time the paint is mixed, a “control log” is first created to assess whether the paint is mixed correctly. Because if the paint is not mixed exactly right, the whole 350 kg batch goes to waste and that is a shame.
