Ceramics
Includes pottery, porcelain and stoneware. Ceramics refers to any item made from clay and fired in a kiln (from the Greek keramos meaning clay).
Cleaning
Generally clean with a soft brush. For bad areas gently clean with warm water (and preferably distilled water) with a small amount of washing-up liquid.
Apply with slightly dampened cloth or use cotton wool or a cotton bud. Also, an artist's brush should be used to clean intricate and delicate pieces.
Wash one item at a time preferably using a plastic bowl for protection.
For delicate pieces, clean only small areas at a time and dry immediately.
Do not immerse in hot water, do not use dishwashers, do not scrub and do not use strong abrasives or detergents. Detergents may expose and damage repairs if present.
Note, unglazed pieces which are absorbent, should not be exposed to water.
Repair
Do not paint, glue or attempt to repair broken ceramics yourselves. Consult a professional conservator.
Treat all ceramics that have repairs with special care. Heating, even gentle washing, etc., can easily expose, weaken or stain the more porous repaired areas.
Minor stains can be treated with a solution of hydrogen peroxide with a few drops of ammonia using a cotton swab.
Display
Display cabinets are generally the most suitable display media for ceramics (the greatest danger for any ceramic are cracks or breakage)
Avoid areas prone to vibration and unstable shelves that can be easily jarred or "knocked".
Plates can be displayed using plate stands but ensure that these are of the correct size, are robust and stable and sufficient space is provided between each item on display.
For best protection, free standing items items can be placed on a piece of felt, cut to size to fit the base, but do not glue felt to the item.
Wire wall mounts for plates are not generally recommended, but if you feel you need to display plates on a wall use plastic coated wall mounts of the correct size.
Ceramics can also be affected by sunlight, rapid variations in temperature and humidity and smoke so avoid direct sunlight and areas prone to coal or cigarette smoke.
Handling
Always hold with two hands, support by the base and set down gently.
Preferable wear white cotton gloves. Fingers can leave greasy marks that eventually may also stain.
Do not hold cups, vases or pots by their handles. These areas are often weakened by age.
Always be aware of loose pieces such as lids etc. Remove these pieces and carry separately.
Storage
Always store by wrapping in acid free tissue (newspapers are very acidic).
If storing more than one item make sure that they do not touch.
Always pack firmly (but not over tightly) to ensure that there is no movement.
Clearly label packed boxes.
