Ceramic School Trophy Glaze Crazing: Record Surface Lines Before Cleaning or Display
Intent: research — ceramic school trophy glaze crazing describes a network of fine lines in the glaze surface of a ceramic award — a condition that may be intentional, age-related, or both, and that looks markedly different from a crack through the ceramic body, a loose patch of separating glaze, or an old adhesive repair join. Recognition-program staff who encounter these surface lines on a historic ceramic plaque, tile award, or decorated trophy need one thing first: a documented intake record created before the trophy is cleaned, repositioned, or placed in a display case. The Canadian Conservation Institute’s guidance on ceramics and glass preventive conservation makes clear that handling and condition decisions for ceramic objects require careful visual assessment — and that probing, flexing, tapping, or wetting a surface cannot substitute for that assessment. This guide explains what to look for, what to record, and when to stop and seek conservator guidance rather than proceeding with cleaning.
