Galena Research Papers

A historical misfired lead glaze produced with galena is also studied. The presence of galena, lanarkite and mattheddleite Pb10(SiO4)(SO4)2Cl2, is determined and discussed in terms of the composition of the galena mineral used and the firing conditions in light of the high temperature transformations previously obtained. ...
