One of the biggest advantages of pipes is that they can be made out of practically anything. Traditionally pipes have been made from wood, bone, or ivory. These days, however, you’re much more likely to come across pipes made out of glass.
Glass is a fantastic material. It’s cheap, easy to shape, can be stained a huge range of interesting colors, and best of all; it can be treated to be heat resistant. Glass pipes are popular because of their superior cooling and non-reactive nature which provides fantastic hits.
Metal pipes are also incredibly popular, thanks to their rugged design and great cooling abilities. Silicone and plastic pipes exist, however buyers should be careful to choose these pipes from reputable brands.
Wood pipes also exist, but they tend to be rarer collector’s pieces.
