Tempered or stressed glass, ie, it has a mechanical shock resistance up to five times more than any other untempered glass. Tempering is a treatment that is applied to the article during manufacture. This is a complete tempered, ie, both inside and externally.
Being temperate, the vessels offer a resistance to mechanical shock which lengthens life up to 5 times more than in non-temperate products.
Also resist temperature shocks or thermal shock (temperature change) of 135 degrees, so they can move from one oven to contact with cold water without breaking.
In the case of breakage, it is tempered, the glass breaks into small pieces less sharp.
