Chat Online· Feldspar is apparently in largest quantity and is composed of both potash and plagioclase species. Occasional grains of micro- cline are recognized which show the characteristic microcline twin- ning. The unstriated feldspar grains so strongly resemble quartz that it is impossible in many cases to distinguish them without the
Chat Online· Potash feldspar has the lowest temperature of fusion a desirable property for its use in pottery manufacture the fusion is still lower if a small percentage of soda is present. Albite is sometimes mixed with a pure potash feldspar to lower the melting point. Lime in feldspar causes a higher melting point and it also causes the articles to
