Collectively, Nathan Allan Glass Studios Inc. is an artist, and glass is their canvas. The Canada-based company produces glass in dozens of unique textures, and the company's focus on R&D aims to retain an innovative and competitive edge by coming up with surfaces that others cannot.
Their latest finish, Crackle (directly above), was formulated for the Rockwell-Group-designed Maboussin USA flagship store in NYC. In grossly oversimplified terms, Crackle is produced by melting glass shards to a substrate and laminating that to a mirror. (The actual production reality is a bit more complicated, but unsurprisingly no detailed instructions have been made public.)
Crackle is just one of the more than 65 types of glass Nathan Allan can produce. Take a look at the varieties here.
