The Agriculture Ministry will use a peacock emblem bestowed by Her Majesty the Queen to authenticate Thai silk and protect the reputation of the fine cloth from imitation fabrics. The Queen has spent years trying to preserve traditional methods of weaving silk that are considered part of the national heritage, caretaker Agriculture Minister Sudarat Keyuraphan said.

The quality of Thai silk had not previously been certified officially. This lack of standardisation had made it hard to maintain quality. The peacock emblem would be a guarantee of quality, make Thai silk more competitive globally and protect silk farmers from exploitation.

The national silkworm commission will scrutinise new criteria dividing Thai silk into four grades based on specific silk types and production processes, including weaving and dying, she said.
The oval peacock emblem will be in four colours indicating quality _ gold (premium, traditional methods), silver (classic Thai, specific silkworm breeds), blue (Thai silk, allows chemical dyes) and green (blends with other fabrics).
