The above is the title of a new process for tinning iron articles lately patented in France, and invented by M. Mare, of Nantes. The articles to be tinned are first scoured with diluted sulphuric acid, and when quite clean are placed in warm water, alter this they are dipped in a solution of muriatic acid, copper, and zinc, and, lastly, plunged into a tin bath to which a small quantity of zinc has been added. When the tinning is finished, the articles are taken out and plunged into boiling water The operation is completed by placing them in a very warm sand bath. This last process softens the iron.
