Abstract
A hinged protective collar for a kiln with rigid first and second body portions, each with a shape and size corresponding to the shape and size of a portion of a peripheral edge surface of the kiln sidewall and a hinge structure that pivotally couples the first and second body portions so they can be pivoted from a collapsed configuration to an expanded, use configuration. For a kiln with a faceted shape, each of the first and second body portions has a given number of corresponding facets. The hinged protective collar can span a portion of the periphery of the kiln, or the hinged protective collar could span 360 degrees and could have first and second hinge structures coupling the first and second body portions. The first and second body portions can have upturned proximal and, additionally or alternatively, distal end portions to prevent damage to kiln brick.
