Because genuine clay brick is
made from natural materials.
Brick
made from clay and shale-some of most abundant, natural materials on earth-and
then fired through a kiln at up to 2000 degrees. The reason the brick turn into
such a durable material is that the clay/shale unit actually goes through a
vitrification process in the kiln, which enables the clay particles to fuse
together.
Many
people may confuse clay brick with “brick” made from other materials. For
example, concrete units rely on a cement paste to bond the materials together.
Moreover, concrete units inherently a grayish color, which means that users
must inject color pigments before the
setting process and use color sealant afterwards to have a color affect.
