HercuGlass - Ultra Break-Resistant Real Glass


Have you done all the work of canning your favorite fruits or vegetables and then had the glass break??  No more!   Our HercuGlass-treated home canning jars are as close to unbreakable as you can get with glass.   In tests, our HercuGlass treated 8 oz. glass bottles and jars have withstood multiple drops from up to 8 feet without fracture.   Just how much abuse the glasses withstand depends on the size, weight and capacity, but all are the strongest canning jars you can buy, and we guarantee substantially reduced breakage rates.   

NOTE:  All HercuGlass mugs are "thermal shock resistant".  You can pour boiling water, cider, coffee, etc. into a cold cup and they WILL NOT fracture.  We will replace any such fractured mug free.  All you need do is send us the mug - we analyze to see how it broke, so we can learn more about our process and how to improve it even more.

We have most of the popular sizes and styles, but if you don't see what you want, let us know and we'll try to get it for you.
