The Unbreakable Glass

The French papers speak of the new Bastie glass as an articlo of nndonbted value, capable of many importaut applications. It is tougb as well as hard, resisting the action of fire, and can be made specially serviceable f or water conduite and a variety of oulinary utensils, instead of the enamel or the leaded tin now so much employed in certain departinents of hardware trade. An account is published of some additional experimenta made in Paris to test the value of the article, the resulta appearing to have been remarkably aatisf actory. Thns, thin platea of the material were thrown on a tiled floor from a height of three metres, that is, a little more than nine feet, without injury ; they were then hurled with violence about the room and against the walls, and held over gas jets, a weight of one hundred grams being also dropped on them from a height of three metres, but all without any effect. As is well known, the resisting temper of thia new kind of glass is obtaiued by means of a chemical bath, to whicli it is subjected when hot from the furnace. In these experimenta some of the specimens showed more resisting power than others ; those which yielded to the blows which they received only broke in the spots where they were hit, and there was a remarkable absence of continuous craclia - wherever the hammer took effect the glaas lost cohesión and tranaparency, and was reduced to granulous particlea.
