Mounting French Crystals
The glass for mounting, whether flat or convex, should be the same size
as the picture. It should be dipped in water and permitted to drain
off, but do not dry it; pour a little of the compound on the side
against which the photograph is to be placed--the hollow side, if the
glass is convex--let it drain off and lay the picture face down upon
it. With the thumb and finger commence at the centre of the photograph,
smoot
ing it down close to the glass, forcing all the air bubbles out
to the edges, thus continuing until the picture is entirely smoothed
out, and at every point in actual contact with the glass. During this
process hold the glass at an angle, so that you can see if there are
any air bubbles or glistening places in it by examining its face
occasionally; and always let a little of the compound get on the back
of the photograph, as it allows the fingers to glide over it more
easily and lessens the chance of tearing it. Now take a second glass
the same size as the first, and having thoroughly cleaned it, fasten it
to the back of the other by small strips of gummed paper. Then place a
piece of card-board of the same size on the back of the two glasses and
fasten the three together also with small strips of gummed paper;
finally securing the whole firmly together by binding it with some
large strips, and your picture is ready to frame. In case you do not
care to frame it, cut out a piece of some dark fancy paper, a quarter
of an inch on each edge larger than the picture, and fasten it, dark
side out, on the back, allowing the quarter of an inch to lap over and
be pasted on the face, after which straighten the edges with a ruler
and sharp knife.
