AFTER an electrotype is removed from the depositing solution, it is "finished;" that is, trimmed, backed, and mounted, if it belong to the printing class, or trimmed and joined to its corresponding section if it belong to the art electrotype order. The finishing of printing electrotypes is by far of the greater importance, and requires the exercise of the best skill; it generally is, and always should be, a distinct operation, performed by special workmen trained to it. In most cases the finishing and correcting of printing electrotypes demands the attention of more than one special workman, as will be judged from the condensed description of the whole process given herewith. Finishing of Print1ng Surfaces.--When the electrotype is judged to be thick and rigid enough (-jijnd of an inch for backed work), the mould is removed and well washed. It is laid electrotype upwards and hot water poured upon the latter; this has the effect of softening the wax and freeing the shell. When any fragments of the shell hang over the edges of the mould they should be clipped off previous to heating. A minute examination should be made at this stage of the face of the shell in order to find any defects that may exist, especially pinholes. Tinning.--The backing process is preceded by that of tinning, in which floating or tinning-pans and the backing metal bath mentioned at p. 137 are employed. The tinning-tray is first floated upon the molten metal until quite hot; the electrotype is laid upon it, face downwards, and a quantity of hydrochloric acid, in which zinc has been dissolved to saturation, thoroughly brushed over its back. This solution of zinc is usually called tinning or soldering fluid, and should be kept...
