Synthesis Glass creates hand blown glass creations in Portland, Oregon. The first time I saw a Synthesis Glass hand blown glass hand pipe I knew I had to add them to the Smokin Js product line-up. What Synthesis Glass lacks in product variety they more than make up for in design and quality. Synthesis Glass creates amazing color changing glass pipes with three dimensional effects unlike any other glass blower in the industry. Each glass pipe features the hand blown fuming work that has become famous to Portland, Oregon.
