Abstract

A bowl for evaporation of a substance for inhalation comprises a cylindrical wall attached to a base. The bowl is made of a colorless single-crystal material selected from the group consisting of: alumina, magnesium-alumina spinel, yttrium-aluminum garnet, and cubic zirconium oxide. The bowl can have any desired color by doping the colorless single-crystal material by a transition metal. The transition metal is selected from a group consisting of: titanium, vanadium, chromium, iron and cobalt. The substance for evaporation can be positioned inside the bowl. In one embodiment, the bowl comprises a tapered cylindrical wall attached to a base. The tapered cylindrical wall can preferably be in shape of a truncated cone to which the base is attached.
