Running 3 furnaces which flow into 9 production lines, we produce 3,600,000 pcs each month. Borosilicate glass is manufactured to handle large immediate changes in temperature without shattering. It can go directly from the freezer into a 350-degree oven, and after heating, can be put directly into a sink full of water without worry that it will shatter. It is non-porous, won't absorb food odors, flavors or stains, is highly hygienic and will never go cloudy even after years of use.
