December 19, 1891. John Kreusi, Esq., Gen’l. Manager, Schenectady Works, Edison Gen’l. Electric Co., Schenectady, N. Y. Dear Sir:- We will express to you to-day fifty lbs. of white compound for trial; included in the same package will be a sample of the same compound applied to wire by hand. This compound is made a little more flexible than the large #1 samples of wire and not quite so soft as sample #2. It is intended to be applied to the wire in a molten state, in about the same manner as your grade #1 wire is made. This compound can be made for 9 cents per pound. It requires no drying or seasoning and is ready for packing as soon as the wire becomes cold. Directions as to heat etc. Will be found on the attached sheet. Hoping that this compound will prove satisfactory We are, yours truly, THE EDISON LABORATORY By Thomas Maguire DIRECTIONS FOR WORKING WHITE COMPOUND The white compound should be melted in a tinned copper kettle, or in an agate glazed iron kettle as it is apt to be discolored by an ordinary iron kettle. The heat should not be raised any higher than just sufficient to melt the compound, which should be constantly stirred while on the fire. This can be conveniently done in a steam-jacketed kettle in practice. When the mass has become fluid enough to run, it is ready for passing the wire through. The wire is passed through in the same manner as grade #1, and when cold, burnished in the usual way.
