Vaeieties of Tiles.
The varieties of tiles as now made may be classed
according to their manufacture, irrespective of form or
use, as follows :—
1. Plain tiles, unglazed, glazed or enamelled, in colors.
2. Encaustic tiles, unglazed or glazed.
3. Majolica tiles.
4. Enamelled, decorated or painted tiles.
The plain tiles are usually made from natural clay mix-
tures, selected with reference to their colors when burned;
or coloring substances may bo added. The color pervades
the whole tile like a brick, not being, as in the case of an
enamel, merely superficial. The addition of a transparent
glaze makes the color more brilliant, and gives a smoother
surface. The general colors of both the plain tiles are
black and white, red, chocolate, salmon, drab and buff.
But almost any desired color can be given to plain tiles,
by enamelling them upon the surface with opaque enamels.
For this process the plain white, buff or red tiles are
taken. Bright reds, crimson, purples, blues, greens and
browns may thus be obtained. These enamelled tiles, like
the glazed, have a smooth glassy surface, and are more
appropriately used' upon walls than in pavements, where
the attrition would soon destroy the gloss of the enamel
and produce scratches. The smooth surface is also rather
slippery and dangerous to walk upon. For these reasons
