This JMass X SPG Mug is a collaboration between JMass and SPG. This mug is made from “Pink Slyme” colored borosilicate glass.
Texan artist, Jay Massey, has been blowing glass since 2006. He helped to build Austin Flameworks out of Austin, TX, and is known for his spore rig style. You can find him on his Facebook.
Yet another artist out of Austin, TX, SPG or S. Pierce Glass was founded in January of 2012, and has been making awesome glassware ever since. While he is probably more well known for his tubes, the shape of this mug is definitely all SPG. You can catch more of his work on his Instagram.
