Pitchers (ceramic material) : ウィキペディア英語版 | Pitchers (ceramic material) Pitchers are pottery that has been broken in the course of manufacture. Biscuit (unglazed) pitchers can be crushed, ground and re-used, either as a low-percentage addition to the virgin raw materials on the same factory, or elsewhere as grog. Because of the adhering glaze, glost pitchers find less use.〔''In USA, Lower Limits For Leaching Of Lead From Ceramic Pitchers. Industrial Ceramics''. No.840,1989,p.517〕〔''Dictionary of Ceramics'' 3rd edition. Dodd A., Murfin D. The Institute of Materials. 1994.〕 The crushed material can also be used in other industries as an inert filler. Archaeologists call ancient pitchers sherds or ostracons ==References==
