If you go to www.glass-smart.blogspot.com and look at the left side you will find 22 links to manufacturers you have never heard of. Over the next year I will be growing this number to about 60 links. As I have started to do with the last post written for the 2018 IWCA convention I will be writing about all of them. They all have very unique products. Hundreds of different products. Which I will be writing about in “Product Reviews”.
