CHAPTER XXV.

ENAMELLING PRINTS.

There are several modes of enamelling prints, but there is none better

than that described by Mr. W. England, which we quote in his words.

"I have a glass having a good polished surface (patent plate is not

necessary), and rub over it some powdered French chalk tied up in a

muslin bag. Dust off the superfluous chalk with a camel's hair brush,

and coat with enamel collodion. I find it an improvement to add to the

collodion usually sold for the purpose 2 dr. of castor oil to the pint.

When the collodion is well set, immerse the plate in a dish of water.

When several prints are required to be enamelled, a sufficient number

of plates may be prepared and put in dishes; this will save time. Now

take the first plate, and well wash under a tap till all greasiness

has disappeared; place it on a levelling stand, and pour on as much

water as the plate will hold. Then lay the print on the top, squeeze

out all the water, and place the plate and print between several

thicknesses of blotting-paper to remove all superfluous moisture. The

plate, with the print in contact, should now be placed in a warm room

to dry spontaneously, when the print will come easily from the glass.

Care should be taken not to attempt to remove the print till quite

dry. If the pictures required to be enamelled have been dried, it

will be necessary to rub over them some ox-gall with a plug of soft

rag; otherwise the water will run in globules on the surface, and make

blisters when laid on the collodion.

"I may mention that prints done in this way lose their very glossy

surface on being mounted, but retain their brilliancy, which I think is

an improvement, as I dislike the polished surface usually given to the

print when gelatine is employed."
