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
