This week we plan to tell the story of how Emile Berliner and Fred Gaisberg set up their record company in America. Seven blog entries on seven days. This is day #4. We’ve reached 1895 and whilst Gaisberg and Karns are on the road trying to find investors for the new gramophone business, Emile Berliner is busy improving the quality of the new-fangled recording discs.
Gaisberg later recalled how Berliner worked on the discs. “Berliner had been using “ebonite” or vulcanised rubber for pressing records. Ebonite required a great deal of pressure and would not retain the impression permanently. Pondering over this, he remembered that the Bell Telephone Company had abandoned vulcanised rubber and adopted a plastic for their telephone receivers.
The Durinoid Company of Newark NJ were button manufacturers who undertook to furnish pressings of a similar substance from the matrices supplied by Berliner. The new substance was a mixture of powdered shellac and byritis, bound with cotton flock and coloured with lamp black. It was rolled under hot calenders into “biscuits”. when heated these “biscuits” were easily moulded under pressure and when cooled they retained the impression.
I was present when Berliner received the first package of gramophone records from the Durinoid company. With trembling hands he placed the new disc on the reproducer, and sounds of undreamed quality issues from the record. It was evident that the new plastic material …had under pressure poured into every crevice of the sound track bringing out tones hitherto mute to us. Berliner shouted with excitement, and all of us including the venerable Werner Suess, our seventy eight year old mechanical genius…danced with joy around the machine.”
According to Gramophone Magazine “Shellac continued to be the basis of all gramophone records for nearly 50 years (until vinyl records appeared during the 1939-45 war) except for such odd novelties as edible ‘chocolate’, and celluloid faced postcards. Record diameters increased from a tiny 125mm (5 inches) through 175mm (7 inches) to the eventual 250 and 300mm (10- and 12-inch) standards, giving playing times of 1, 2, 3 and 4-1 minutes respectively. Double-sided records came in at the turn of the century.”
