were hand-mounded from moist clay and
then sunbaked, as is still the practice in certain arid climates.
The firing of clay bricks dates back well over 5000 years and is
now a sophisticated and highly controlled manufacturing
process.

A

BRICKS AND BRICKWOODS

18

BITUMEN

24
Q

refers to materials which act as adhesives.
- is a binder, a chemical substance used for construction that
sets, hardens, and adheres to other materials to bind them
together.
