employees, such as Mr. Storms, in order to learn their secrets. Unfortunately for Columbia, the names of the components used by Edison were not labeled with ingredients but were instead indicated by number (i.e. 1, 2, 3) keeping the identities of these components a secret. Paraffin, ceresine, and ozokerite all look similar, making the tempering agent even more difficult to identifify by the wax mixer. Wax mixers were given instructions on how much of each numbered component to put in the mixture, and how to process it, but no idea as to what the ingredients actually were. It took over a year for Columbia to come up with the formula for cylinders. Columbia placed an ad in the Soap Makers' Journal for a practical man to work with metallic soaps. Adolph Melzer, a soap manufacturer from Evansville, Indiana took the job. Melzer devised a formula comparable to Edison's with the exception of the tempering agent (using cocinic acid, derived from coconut oil instead.) In 1901 The Gold Molded (originally spelled Moulded) process was perfected for commercial use by Thomas Edison and Jonas Aylsworth (Edison's Chemist) with input from Walter Miller, the Recording Manager of Edison Records. This discussion was gleaned from facts provided by Walter Miller, Jonas Aylsworth, Thomas Edison, Adolphe Melzer, and Charles Wurth. At first, no method of mass production was available for cylinder records. Copies were made by having the artist play over and over or by hooking two machines together with rubber tubing (one with a master cylinder and the other a blank) or copying the sound mechanically. By the late 1890s, an improved mechanical duplicator, the pantograph, was developed which used mechanical linkage. One mandrel had a playback stylus and the other for recording, while weights and springs were used to adjust the tension between the styli to control recording volume and tracking. The Edison team experimented with Vacuum Deposited Gold masters as early as 1888, and it has been reported that some brown wax records were molded, although this is unproven. The Edison Record, "Fisher Maiden", was an early record that was experimented with for the process. The 1888 experiments were not successful due to the fact the grooves of the cylinders were square, and the sound waves were saw-tooth-shaped and deep. The records came out scratchy and it was very time-consuming. The Gold Molded process involved taking a wax master and putting it
