GLASS BRICKS

CHALLENGE TO THE KILN PRODUCT Although it is questionable whether costs of production are sufficiently low to bring glass bricks into serious competition with the familiar products of ohe kiln, it is conceivable that traditional ideas will be greatly modified as the new material passes through the experimental stage, it is claimed, however, that the glass brick is destined to play an important part in the revi.al of structural developments, and may radically alter building designs and styles. Apart from the beauty aspect of glass, it is said that the glass brick has proved of tremendous value in transmitting and diffusing tight. One manufacturing firm in America has produced a glass brick, and is constructing a two-story laboratory entirely of the material. The building will bo without windows, and will be air-conditioncd. An improved glass brick or block, which reduces heat flow, deadens sound, transmits and diffuses light, deflects sun glare and resists fire, and can be laid in practically the same way as any other bricks used in standard building construction, has already appeared on the market. It is treated by a special process or enamelling and sanding, and the mortar is so bonded as to prevent water _ leakage. The adhesiveness of the brick is obtained by an application immediately alter it comes from the oven of a special enamel to the side which fits against the mortar. Another coating of enamel is applied to thicken it in preparation for a dressing of sand. The finished mortar-bearing surface is rough TRAINING YOUNG CRAFTSMEN. According to an article in London ‘ Jing ; ineoring,’ the building industry in parts of lingland is experiencing difficulties in obtaining and training craftsmen. A recent expansion in activities, it was explained, had not been followed by an increase in the number of apprentices attending technical schools. These, however, might consider how far they might improve their methodsof instruction and practical tuition. New materials, now supplementing those formerly in use. should he utilised in training schools, and the scientific aspects given greater attention. Thus the young craftsman would be able to avoid the pitfalls of faulty work. The prevailing demand was for economical and sound construction, which was dependent upon the skill and knowledge exhibited in architectural and building practice.
