A Prague correspondent writes:
The firm of Kavalir, who have glass works at Saxava, and also in the neighbourhood of Karlsbad, a firm which is well known in England, after some years of experimenting, have recently perfected the manufacture of glass utensils of every description, for which. it is claimed that they are unbreakable and can be utilized not only for the table and ordinary purposes but also as cooking utensils. Dr. Horak, the manager of the Kavalir Works and Secretary of the Associated Glass Manufacturers, recently gave a lecture on this subject. He placed -some tumblers on a red-hot stove, each of them one millimetre in thickness, and put some wood into them. The wood became charcoal, and the tumbler remained absolutely without blemish. The temperature must have been at least 300 degrees Reaumur. Dr. Horak also placed in the tumblers some tin, which was melted without harm to them. As every description of cooking utensil can be manufactured from this glass, it is quite probable that on account of its durability, cheapness, and cleanliness a reformation in the articles at present in use may take place. With regard to table glass, tumblers were thrown heavily on the floor and received no injury. International capitalists are, I understand, interesting themselves in this remarkable invention.
