Lit. salt glazed tile. A process used to frost-proof
roofing tiles. A small quantity of salt is thrown on to the exceedingly hot, baked
tiles (biscuit ware) from which steam is emanating. The combination of salt and
steam produce a rich alkaline glass coating over the tile. Because this glass
coating has a low moisture content, it is unlikely to be damaged by frost. Tiles
of this type are common to folk dwellings in cold areas along the Japan Sea and
throughout northern Honshuu 本州. The majority of red tiles produced in Aichi prefecture
use this method. |
