Pipes made from silicone can offer the best of both worlds: an interesting and unique shape as well as something unbreakable and dishwasher safe. For those looking for an elephant pipe but has heard they are too fragile to use often, then a silicone version would be the next best thing. On the other end, for those looking for intricate pieces, glass sculptures, then note that glass can be made into more complex and rich textures and colors than silicone.
