What is a common result of improper venting during the installation of plastic fire clay?

Improper venting during the installation of plastic fire clay can lead to structural failure. When fire clay is improperly vented, it can trap moisture and gases that need to escape during the curing process. This trapped moisture can create pockets of steam, which may cause the clay to expand unevenly. As a result, this uneven expansion can weaken the overall structure of the installation. In extreme cases, if the moisture or gases do not escape properly, the material can crack, warp, or even collapse, resulting in a failure of the structure. This emphasizes the importance of proper venting to ensure that the material cures correctly and maintains its structural integrity.
