Hey great information on the different grades of wood stove glass...but come on let's mention the overseas country and those big box stores we get the lower grade glass LOL

Corning which developed the Product and the Copywrite, usually does not manufacture their own Glass. What they do is sell the license to manufacturers to make it under their name. So the East Coast of the US will get the glass from France. West Coast and Canada get it from China. However, China does not have the License. Japan outsources it to China. Pyroceram III from France now only does the rolling of the product, but now it's sent back to the US for Annealing, which is needed to allow cutting of the glass. Robux, Neopream, are the names of the products from China.
