In Response To: How to clean parian... (Jude Hubbard)

First you need to determine if the item is unglazed vitrified porcelain, unglazed non-vitrified pottery, underfired porcelain or soft paste porcelain. The reason being is that porous bodies will absorb soluble cleaning compounds(like detergents)which will re-emerge with potential problems later on. Determining the manufacturer is often the best clue or conducting an absorbtion test. If the item is vitrious, you can use a tooth or stencil brush with an enzyme detergent like Bio-Tex or a mild dish washing liquid (not dishwasher!). Cover up the metal ferrule on a brush with tape to avoid metal markings. Metal markings can be removed by using an ink eraser. For greasy or very dirty vitrious objects, you may need to let it soak for several hours. Use plenty of fresh water to rinse the object and dry with a clean white towel. Avoid the use of abrasive materials which may scratch the surface. Steam wands are also very useful in cleaning parian. If the object is porous you may wish to let a conservator/restorer clean it for you in order to avoid potential problems.
