[NB050095], Technical Note, Jonas Walter Aylsworth, December 6th, 1888

Editor's Notes

On Preserving Records of Sounds on Wax Cylinders##The idea is to coat the cylinder with a thin film, that will not wear under the influence of the (receiver or reproducer) stylus, or by handling ect. Such a film might be a separate compound as colodion, varnishes, silicates (soluable). The might be applied by brush or by dipping in solution of the film required, the solvent afterward draying and leaving the film on surface of wax. Or the cylinders might be composed of asphalt compounds or something which when after ward treated would become hard on surface. This might be done by pentichloride of antimony and other chemicals.
