GRAMOPHONE RECORDS.
USE OF NEW MATERIAL. REMARKABLY LIGHT AND HARD. Gramophone records from a new flexible material, dtirium, itavc arrived ill Auckland. Made of flexible cardboard, the disc is surfaced witii the new material, which is of remarkable hardness and durability. The records are said to be unbreakable, and it is claimed for them that they will not scratch. A test for quality and tone was made with a sample record recently, and it was found that remarkable richness and depth was reproduced. Dtirium, the new material, is a synthetic chemical compound, first produced iu lf-7. It is hard and smooth as a diamond, yet a thin sheet of it is surprisingly pliable, it is non-iiillaminable, waterproof and extremely light. At a certain stage of its manufacture, it sets instantaneously, and retains ifs impression precisely under all conditions of heat and cold. The result is that it becomes possible to make gramophone records of qualify with heretofore unknown speed.
