Ceramic plates often carry sentimental as well as physical value. Breaking a plate from a set does not have to be a big deal anymore. By following a few simple steps, anyone can repair their broken or cracked plates. When a plate breaks, gather all the pieces and store them in a safe place until they are repaired. This method works best on plates that crack in half or break into a few large pieces. Shattered plates broken into many different shards should not be repaired using this method.
Clean the surface of the broken plate using a mixture of dishwashing liquid and warm water. Scrub away any stains using a scrubbing sponge. Allow the plate to dry completely.
Paint both edges of the broken area with PVA white glue using a small paintbrush. Use only the amount necessary to coat the broken edges. Too much glue can make it difficult to fit the pieces together evenly, while too little glue may create a weak bond.
Join the broken edges together, pressing firmly to ensure the bond holds tight. Hold for at least one minute.
Fill a shallow container with uncooked rice or beans, and place the repaired plate into the container on top of the beans. This creates a bed that allows the adhesive to continue drying and prevents the plate from shifting or re-breaking. Allow the adhesive to dry for one hour.
Scrape any excess glue from the plate's surface using a razor blade. If the glue does not come off easily, dip cotton swabs in warm water and use them to remove the extra adhesive.
Place the plate back into the shallow dish and allow it to dry for 24 hours.
Protect yourself when handling broken pieces of pottery by wearing sturdy gloves, as serious cuts can result from sharp edges.
