Real Silk or Fake: How to Verify Upon Delivery
Shop the Silk Pillowcase →The Burn Test, the Most Reliable but Destructive
An isolated thread of real silk burns slowly, gives off a smell close to burnt hair, and leaves a crumbly ash that crushes easily between the fingers — a synthetic, by contrast, melts, smells like plastic, and forms a hard bead as it cools.
Three Simple, Non-Destructive Tests to Do Upon Delivery
Rubbing the pillowcase between your hands generates a slight, noticeable warmth with real silk (unlike polyester, which stays cold), the fabric produces no rustling sound, and a quick pass under water makes it noticeably softer, never sticky or plasticky.
"The simplest test that damages nothing: run the pillowcase under cold water for a moment — real silk becomes even softer when wet, while a synthetic stays the same or even feels slightly sticky.
"
| Test | Real Silk | Synthetic (Polyester Satin) |
|---|---|---|
| Warmth on rubbing | Noticeable | Stays cold |
| Noise on movement | Silent | Rustling/crackling |
| Contact with cold water | Softer | Same or sticky |
Three Senses Engaged Beat a Label Alone
Combining touch (warmth, softness), hearing (silence), and quick contact with water gives a reliable verification in seconds, without needing to sacrifice a thread for the burn test.
