This stocking, made by the Stewarton Hosiery Company Ltd, shows the flexibility of fibreglas. Glas fibres were known to the ancient Egyptians and are defined as any fibre drawn as a thread from molten glas. The glas thread can then be wound upon a spool and used as an alternative to silk or cotton in many woven and kitted goods. It is also used as a reinforcement material for polyester and epoxy resins in structures such as aircraft radomes and racing car bodies.
