I was wandering the internets looking for glass tiles and came across a great site where they make glass tiles out of 100% recycled glass. It’s Glass Roots of Montana. Not only is their glass recycled but they utilize solar energy to get the job done. Super cool! And they have a description of the colors available and the bottles they come from. Very inspiring…I’ve been playing with bottle glass lately and the colors are just so beautiful. But always remeber if you’re going to use bottle glass that ou only use it with itself…no mixing. They may not be compatible and if you mix them in the torch or the kiln you may end up with broken and no one wants that.
