It was designed by me in my SC studio. I am a glass artist and have knowledge of the correct compatibilities of glass. I have worked with glass for 29 years now. All of my pieces have been made using the correct glass and fired in my kiln up to 1480 degrees and then cooled using an annealing program for cooling down and takes up to 24 hrs...annealed for added durability. Made in the USA.
