Publisher's Synopsis
Excerpt from Knowledge, Vol. 8: An Illustrated Magazine of Science Plainly Worded Exactly Described; July to October, 1885
The electricity necessary for the gilding is derived, in some cases, from the well-known Daniell battery, and in other from dynamo-electric machines. There is little doubt that the great amount of attention recently bestowed on dynamos for the purpose of electro-deposi tion will speedily result in.the exclusive use of those machines in places where a considerable and steady ?ow of 'work has to be got through. It is stated that the works of every thousand watches absorb in the gilding processes eight to ten pounds' worth of the precious metal. As our readers are doubtless aware, the gilding solution is of a highly poisonous nature, and the fumes or vapours arising therefrom are none of the healthiest. To get rid of these, an exhaust-fan is provided to free the room of such impurities.
