In ancient Egypt, the core-forming technique was the primary method for creating glass vessels, a practice that reached a high level of excellence during the 18th dynasty.12
The process involved several distinct steps:
- Core Preparation: A core, typically made of clay (often mixed with dung), was shaped and fixed to a metal rod.1
- Building the Body: The body of the vessel was built up around this core, usually using opaque blue glass.12
- Decoration: While the glass was still hot, threads of contrasting colored glass—such as yellow, white, or green—were coiled around the vessel. These threads were then pulled up and down with a comb-like instrument to create decorative patterns like zigzags, feathers, or arcades.1
- Finishing: The applied threads were rolled into the surface of the vessel, a process known as marvering, to make them flush with the body. Finally, handles were often added, and the core was removed once the glass had cooled.1
These vessels were generally small and primarily intended for storing unguents or other precious liquids.12
