Logjam Glass is handmade in Colorado. He is best known for creating the dab rig design known as the "Swiss Stack", also known as the "Mutant Egg". It's basically a cylinder shaped version of the very popular Mothership Glass design known as the "Faberge Egg". The Swiss Stack vapor rigs by Logjam Glass display very intricate scientific glassblowing techniques. It takes a very skilled glassblower to execute these techniques well. And as you can see below, Logjam Glass is one of those glassblowers. These pieces function great, especially when paired with a "banger" style domeless quartz nail. They are also VERY well priced in comparison to other similar American glass designs, so add one to your wish list or snag one we have for sale now!
