Criminals beware, the Dark Knight hero is on the scene and ready to smoke you out of your mind and into Arkham! Our Dark Knight Dichro Glass Pipe by Chameleon Glass is made from high quality dichroic glass. The sophisticated design starts with the pipe graduating from black into a fritted gray bowl head. Dichro glass contains many micro layers of metal oxides, which provide the glass with dichro properties. The process of creating a dichro label, starts by removing the dichro coating from the glass. Next the label is trapped between two layers of glass, which enhances the image and creates an exact copy of it. This process was used to create the shiny blue Dark Knight label, that proudly lays across this pipe!
