On a New Porcelain Filter [PDF]
Journal of Hygiene, 1906 The use of earthenware as a filtering material for the purification of water is probably of very ancient origin, but the modern modification, the porcelain filter, according to Gautier (1890), is due to Nadaud de Buffon (1861). Earthenware filters in general serve the useful purpose of aërating the water and retaining suspended matter and are therefore

Waste glass in porcelain [PDF]
Materials Research, 2005 In this work, the feldspar used as a flux in typical porcelain was replaced by waste glass, and the resulting batch composition contained 50% kaolin, 25% quartz and 25% waste glass. The properties of this porcelain with glass powder (GP) were compared to traditional porcelain (TP), which utilizes feldspar.
