ELASTIC GLASS.
Two Austrian chemists have invented a substitute for glass, which because of its likeness to opal, they have called "poll-opas." The new substance can be worked on a turner's lathe at a much lower temperature than glass, and is one of the most elastic subtances hitherto discovered. It is much softer, and does not keep out the violet rays of light, and so should be of the greatest use as window glass for hospitals and hothouses. It is easily dyed, and solutions of it can be applied to cloth that will give it a stiff and shiny surface and will not wash out.lt will serve as a binding material in connection with printers' dyes and in the textile and paper industries, and will also be of the greatest importance in colour photography. Poll-opas will probably be manufactured on a large scale in the next few months.
