Learn about turquoise tannins and identification


Tannin is a common optimization method for turquoise. It is also the traditional process in the processing of turquoise. It is to immerse the turquoise raw material in the rubber to strengthen its structure to avoid fragmentation during processing and ensure the yield.

Compared with the past, the current silicone technology is more mature, mostly using transparent synthetic resin, so the color of the turquoise raw material will not change in the process of silicone, but the color will be deepened, because the turquoise is after the silicone. The density and structure are optimized, so the hardness is also increased, and some can also be used to scratch the glass after the product is produced; in addition, the turquoise after the rubber is burned and the odor is small, similar to rosin, we can use this to identify. The above is a brief introduction to turquoise silicone, I hope to help everyone identify natural turquoise.

Also called a medical mask, a surgical mask is a loose-fitting disposable mask that protects the wearer's nose and mouth from contact with droplets, splashes and sprays that may contain germs. A surgical mask also filters out large particles in the air. Surgical masks may protect others by reducing exposure to the saliva and respiratory secretions of the mask wearer.

At this time, the U.S. Food and Drug Administration has not approved any type of surgical mask specifically for protection against the coronavirus, but these masks may provide some protection when N95 masks are not available.
