Unsplinterable Glass

There was a rare scene of glassbreaking at the Criterion Restaurant, London, one day lately, pane after pane being attacked with 1 joyful persistence. The factis that a new safety glass has been invented. It will neither break nor splinter, nor leave the jagged edges that add alarmingly to the dangers of motoring. The glass is an amalgamation of three transparent bodies —glass, glucose, and xylonite. A thin lough sheet of the last named substance is placed between two sheets of glass, with glucose as the adhesive, and welded together under enormous pressure. The result is a product as transpariit as ordinary glass and just a trifle more expensive. The new glass is safe from the attack of the burglar's diamond; it is also soundproof, and is . regarded by experts as being far superior to any form of fortified glass yet invented. The railway companies are experimenting with it, and it is stated that Scotland Yard is watching the results of the demonstrations .with a view, it is believed, of requiring the adoption of the glass on public vehicles. Some of the experiments to which the glass has been subjected have been very severe. An iron ball suspended from -a cord struck a pane of glass with a force equal to that of an ordinary stone weighing one pound thrown at a motor car travelling at forty miles an hour. The galss was starred only one per cent being scattered, and that in the form of powder. A pistol shot was fired at an angle of twenty degrees. The bullet glanced oil 1 the surface of the glass, causing it only to crack.
