Glass beads making is one of the world?s most ancient arts that are still practiced all around the world. Glass beads are classified on the basis of the method of manipulating the glass. Most beads fall into three main categories:
1. Wound
2. Drawn
3. Molded
The earliest beads were formed by the winding method. Beads created by this method were called as wound beads. Wound beads were created by heating the glass at a very high temperature and then molded around a steel wire coated in clay slip. The process is termed as marvering, derived from the French word "marver" which translates to "marble?. These are the types of lamp work glass beads.
