In addition, Thai silk has a unique lustre, with a sheen that has two unique blends: one color for the warp and another for the weft. Color changes as you hold the Thai silk fabric at varying angles against light.
Moreover, Thai silk smells like hair when burned, a testament to the natural fibre that comes from the silk worm, which is similar to the composition of human hair and fingernails. If you move the flame, Thai silk immediately stops burning. Artificial silk smells like plastic when burned.
