How long does a forge liner last?

The lining is composed of two different materials. The walls and top are made of ceramic fiberboard and the hearth brick is made of high temperature fire clay. In addition to the high heat of a Forgemaster and normal wear and tear, there are two things contribute to the breakdown of the lining materials; vibration and moisture. To increase the life of your Forgemaster liner, avoid damage while traveling by securing the forge so that it cannot bounce and slide around in your vehicle. Protect the forge from the elements. Left outside, the forge will be damaged by rain and snow. The moisture will rapidly breakdown the Ceramic Board, and renders the forge useless.
