GLASS MANUFACTURING UNIT

PROBLEM TO BE SOLVED: To provide various units used for glass manufacturing processes which are hardly abraded by molten glass and capable of stably supplied. SOLUTION: Disclosed units are a melter, a refiner, a throat, a forehearth, a feeder and a fusion cell which are used in glass manufacturing processes and brought into contact with molten glass, and each equipped with a thermally sprayed coating film of platinum or platinum alloy formed on a core material of sintered brick. For example, the melter 10, the refiner 20 and the throat 50 are manufactured by combining blocks 11, 21 and 51 comprising sintered bricks formed into prescribed forms, respectively. In these embodiments, contact faces 12, 22, 52 of these blocks with molten glass and mating faces 13, 23, 53 of the neighboring blocks are each formed of a platinum thermally sprayed coating film.
