Sovereignty Glass was started in 2007 by Steve (Machine Maker); a California native who began working with glass in 2000. Steve has engineered some of the most progressive percolator designs in functional glasswork such as the pillar, proprietary StemLine, and gridded G8, Stem8 and Recycler percs. Steve has also produced some awesome Heady collaboration rigs with his glassblowing peers. Sovereignty Glass Bongs and Dab Rigs remain one of the most popular and sought after pieces within the glass community.
