Answer 2

The Silk burn test is the best way to identify silk.

• The silk burn test is used to distinguish natural silk from its synthetic forms, other fibres like polyester, cotton, or other synthetic fibres or blend of silk and other fibres.
• To identify real silk, a thread is extracted from fibre cloth and burnt using a flame of lighter.
• The pure silk will burn only until it is in contact with fire and produce a smell identical to the burning of human hair.
• Polyester is completely combustible and produces a fume with the smell of burning plastic while cotton burns to give the molten ball.
• Hence, silk can be identified from burn tests based on characteristic burning properties.
