word:     Sandblasted

Sandblasting is a style of glasswork characterized by a matte, opaque finish, and a rougher texture than most glass. The finish is made by literally blasting the glass with sand using a blowing tool after the glass is shaped and cooled. The texture gives sandblasted pipes a pleasant handfeel, while the interior of the pipe is still smooth to avoid clogging with tar.
