See How Some Of The More Attractive Decorative Items Are Produced.
It is difficult to believe that for hundreds of years, the production of seed beads has been covered in secrecy. Boasting about the techniques would have cost a Venetian bead maker his life a few hundred years ago and, even today, the Japanese closely protect some of the methods involved in seed bead production.
The term ‘seed beads’, refers to the small beads used in bead jewellery and textiles, which are also affixed to accessories like handbags, shoes, lamp-shades and other decorative items. We like to see them incorporated in our Christmas village collections. They are finicky to work with and can send you scuttling off to the optometrist, but they produce some of the most exquisite, intricate beadwork.
Seed beads come in just about every shape and colour imaginable and may be transparent, foil lined or opaque. Although they are occasionaly made from plastic or metal, they are normaly made of glass. The glass beads produce the best results in christmas villages. You can find some fine examples at Christmas village collections. Understandably, every country involved in making seed beads has their own methods but certain elements of the production processes are similar. For instance, the first step in the process is liquefying silica sand.
While the French heat the silica sand to temperatures above 1200ºC, over a number of weeks, the Japanese heat it over one day. It is at this point, in both cases, that the desired colour is added. Once that is done, part of the molten mix is released from the cauldron, and an air bubble is blown into the molten glass either by mouth or with a shot of compressed air. Either way, this step forms a space inside the molten mix and the mix forms a long, hollow tube of glass, known as a cane.
Once cooled, the canes are cut into ‘beads’, although at this stage, the beads do not resemble the end product; they are dull with rough edges. The beads are then put into a mixture such as clay and charcoal and carefully tumbled, to smooth and shape them. They are then reheated to temperatures between 500ºC-800ºC, depending on where they are made and the type of seed bead the manufacturer is producing. This process burns off the abrasive mixture and adds a yet unseen shine to the beads. They are then washed and dried and finally reveal their true colour and lustre.
