Jewajang refers to the skill of making roof tiles, or to an artisan with such a skill. Roof tiles were used to make the buildings look better, in addition to their inherent function. In olden days, they symbolized the authority and wealth of the building’s owner.
Roof tiles are divided into convex and concave types. Ancillary ornamental tiles include convex roof-end tile, concave roof-end tile, roof tile with demon face design, dragon finial, and tiles placed at both ends of the top ridge.
Looking at how roof tiles are made, sticky clay mixed water is put into a wooden mold. After a period of drying, the clay is cut to an appropriate size and pattern and then put into a kiln, which is heated to a temperature higher than 1000℃. Adequately baked roof tiles are black or silver gray in color.
Each region developed its own unique roof tiles, but concrete or slate-roofed buildings have lately pushed aside buildings with roof tiles. At present, roof tiles are produced only in Ulsan and Jangheung, Jeollanam-do.
