The Ultimate Guide: How to Identify 100% Genuine Mulberry Silk vs. Synthetic | LUME SANCTUARY

The Science of Silk: 5 Professional Ways to Spot Fake Silk

In an era of clever marketing, "silky" and "satin" are terms used to disguise cheap polyester. But synthetic fibers lack the breathable, skin-loving properties of real silk. To protect your skin and your investment, LUME SANCTUARY shares the definitive guide to identifying 100% genuine Mulberry silk.

1. The Burn Test: Protein Doesn't Lie

Real silk is a natural protein fiber. When a small thread is burned, it smells like burning hair and the flame is easily extinguished. The ash is black, brittle, and turns to fine powder when crushed. Synthetics, however, melt like plastic and leave a hard, uncrushable bead.

2. Multidimensional Luster

Synthetic fibers produce a static, white shine regardless of the light angle. True silk has a triangular prism-like structure that refracts light, creating a pearlescent shimmer that changes hue subtly as you move. This is the unmistakable glow of quality.

3. The Static Check

Natural silk is an excellent insulator and holds moisture well, making it naturally anti-static. If a garment clings to your skin or crackles with static electricity, it is a clear sign of synthetic material.
