Popular water pipe materials include glass, acrylic, ceramic and silicone. Glass water pipes are the most popular material on the market since they provide the cleanest and purest taste and glass on glass is the most popular style. Water pipes made from borosilicate glass contain boron trioxide, which has a very low coefficient for thermal expansion. This means it’s incredibly durable and will not crack under extreme temperature changes like regular glass. Compared to hitting a joint or smoking from a bowl, water pipes provide a smoother toke thanks to water (and some ice cubes if you’re feeling jazzy) since there’s no dry heat.
