Bead - technique to produce
Egypt; New Kingdom; 15th c. BC
This is a rare example showing all the characteristics of early glass production, using the cutting technique to produce a ribbed effect, in combination with core-forming. This continued to be the most important technique of glass production until the introduction of glass blowing.
The colours used in early glass production were an attempt to parallel those of semi-precious stones (especially lapis lazuli, turquoise and malachite), and the glass mixture itself was highly prized. The combination of white and blue was for the next two centuries central to the decoration of core-formed glass where thin threads of glass contrasted to the ground colour.
