The video link below shows how firebricks are cemented together at the
Paragon factory. We don't dip the bricks in water, because the moisture
in the kiln cement is not given enough time to absorb into the bricks.
Rows of bricks are dipped into a pan of cement and then immediately
pressed against the next row of bricks.
Also, the cement has to be mixed to exactly the correct consistency. It
has to be as creamy as freshly stirred almond butter.
