It is made of 100% borosilicate glass and is guaranteed to withstand temperatures of up to 350?C.
It is 100% flame proof and can be used directly on the flame.
A practical twist to the original Classic Jar, the square-shaped variant is designed to save precious space in your kitchen. Use it to store pulses and grain, or dry fruits and snacks - the inert borosilicate glass ensures that your food stays 100% pure. In fact, some of our Borosil users even use the Stack N Store variant to freeze breastmilk! Since the jars are flameproof, it is easy to thaw the contents.
