Dear colleagues, I am a Masters student studying the potential effects of biological washing powders on porcelain. Biological washing powders, as a cost effective and readily available source of enzymes, are commonly used for cleaning organic staining from high-fired ceramic objects. The last conservation research into the general components of biological washing powders and their potential effects on ceramic was published in 1993, therefore, a more accurate picture of their use and current effects can be gained through a contemporary investigation.
A preliminary questionnaire that was sent to a small cross section of conservators including private and public sector revealed that the washing powders can “etch” or “leave deposits” on glazed surfaces which can be difficult to remove, even on porcelain. The aim of this study is to determine the circumstances in which this phenomenon occurs and to find safe working parameters for the use of biological washing powders in ceramic conservation. This questionnaire will help to give a better idea of how biological washing powders are being used in industry and may indicate the frequency and circumstances in which this phenomenon occurs. Please take a few minutes to fill in the questionnaire which can be found via the link below. Your input would be greatly appreciated.
