What we claim as our invention, and desire to secure by Letters Patent of the United States, is.:-

1. The process of coating paper, glass or other material with a mixture of collodion solution and powdered metal which consists in applying said mixture to the material, passing the coated material through water, whereby the solvent is absorbed by the water and the residual coating fixed, and subjecting the coated material to pressure.

2. The process of coating paper, glass or other material with a mixture of 'collodion solution and powdered metal which consists in applying said mixture to the material, passing the coated material throu h water, whereby .the solvent is absorbedgr by the water and the residual coating xed, and subjectin the coated material to pressure while un er water.

3. The process of coating paper, glass, cr other material with a mixtureof collodion and powdered metal, which consists in applying said mixture to the material, causing the latter to travel during the application of the mixture, subjectin the coated material to the action of co1 water flowing in the opposite direction to the direction of movement of the material and in contact with the material whereby the solution will be absorbed and the residual coating fixed and finally subjecting the coated material to pressure while under water.

In witness whereof we have signed this specification in the presence of two witnesses.
