Fill a large hand basin Oldish with water, and immerse the photographs in it for a few minutes, allowing them to drain slightly after removal, and then place them with the image downwards on a sheet of glass. Lay over them a few thicknesses of blotting paper and rollout excess of moisture. Now brush over the top one with some Biggins' photo mountant or fresh starch paste, lift it carefully by the; corners and lay in position, cover with fluffless blotting paper, and with a squeegee roll gently twice, if the photographs are to be mounted in an album, wet mounting may cause cockling, and in such case an alcoholic solution of gelatine should be used: Nelson's No. 1 gelatine, loz.; water, 3 oz.: glycerine, 2 dr.; methylated alcohol, 10dr. Dissolve the gelatine in the water, then add the glycerine and alcohol last. In this case the position the print is to occupy is marked on the leaf: and, the print having been dried in contact with glass, a thin coating of solution is run rapidly round the edge of the print or within the line on the leaf with a small brush and the print rolled into contact.
It is always advisable for a beginner to gain skill and experience by practising on wasters or spoilt prints.
