R. W. Pope: The old Boston and Albany line was insulated with what my brother called white flint insulators, and he considered those insulators very much better than glass. That was as far back as '58 (1858). They were abandoned I believe because glass was cheaper and served the purpose. I have never seen any reference to that material, but I remember how those insulators looked at that time, and I have had an idea that they might have been quartz, and their manufacture a lost art.
