1.	Why is lead used in ceramic industry?(a) To increase strength(b) To increase water resistance(c) To increase lustre(d) To increase electrical conductivityI had been asked this question in unit test.This is a very interesting question from Lead in chapter Metallurgical Industries of Chemical Technology
Answer» The correct option is (c) To INCREASE lustre To explain I WOULD say: Lead compounds impart low surface TENSION and low viscosity over a wide TEMPERATURE range which results in smoothness and ADDS lustre.
