PHOTOGRAPHY ON OPAL GLASS.
To the EDITORS.
GENTLEMEN,--I have been much amused to see in your description of the "Toovytype" an exact description of the process of printing upon opal glass that I brought under the notice of the Liverpool Photographic Society many years ago, the only difference being the: use of albumen instead of chlorodised collodion.
I think it would be a great improvement if the picture was printed in carbon, and afterwards vitrified by the means of a layer of flux or soft glass.
I have seen some very beautiful specimens in this direction by Mr. William Gardner, of St. Helens, quite equal to any silver print I ever saw, and thoroughly burnt into the body of the glass.
I see no difficulty in constructing a gas apparatus at small cost for the purpose of firing the glass when printed and coated with the flux.
The public are quite prepared to show their appreciation of a thing of sterling permanence, and I doubt much of the success of a gallery of celebrities unless thus vexed question of permanence is settled.--I am yours, &c.,J.A. FORREST.
58, Lime-street, Liverpool, Nov. 29, 1864.
