Glass Cups

We supply glass cup by soda lime and borosilicate, made by handmade and mouth mlown.

A good glass product must go through the process of hot processing (preform, blowing), annealing (120-180 minutes, stress relief), cold processing

(incising, grinding and baking), and deep processing (engraving, sandblasting, decal, gold decoration and color decoration).

The soda lime cups are pretty glossy and transparent. The borosilicate cups usually with liners like scratch.

The borosilicate cups are lighter but stronger, they will not break like soda lime ones.
