Ian Gonzalez founded La Casa Cotzal and is the protagonist of tranSglass™, a Guatemalan artisan group of La Casa Cotzal. The group collects donated recycled bottles and transforms them into collectible art pieces for client Artecnica. La Casa Cotzal is literally turning "garbage" into a work of superior craftsmanship and design.

The La Casa Cotzal employs 22 Guatemalan artisan women and men who, prior to their work producing tranSglass™, were either unemployed or working as laborers. Now they have learned a craft and take great pride in their ability to work as a team to cut, shape and polish the recycled bottles into art pieces.
