Ever break a plate from a valuable dinner set or grandma's heirloom china? Looking at the shattered remains of a favorite place setting can be a heart-breaker. All too often we're too quick to throw away a broken piece before attempting a professional-quality repair. Do what pro restorers do to get the job done: First, soak everything in a solution of 1-half-cup household bleach and 2 quarts of water. Wash carefully to remove loose debris, and let dry. Then make a mold of the largest unbroken section out of heat-softened paraffin. Press it over the bottom, and when hard, remove and arrange under the broken area; start fitting and gluing with waterproof epoxy. Carefully do only a few pieces at a time as it sets, then slip a sharp knifepoint under excess glue and slowly peel it away. And that's the On The House tip for today.
