Examples

• A clean plate of glass is coated with collodion sensitized with iodides of potassium, etc. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• M. Le Gray, of Paris, was the first to suggest collodion for this purpose, but Mr. Scott Archer, of London, in 1851, was the first to carry it out practically. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• Scott Archer’s Collodion Process in Photography. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• Collodion emulsion with bromide of silver was invented by Sayce and made known in 1864. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• In 1856 Norris produced sensitized dry films of collodion or gelatine (British patent No. 2,029, of 1856). Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• Besides its use as an explosive, gun cotton when dissolved in ether has found an important application as collodion in the art of photography. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• Albumen has, however, been supplanted by collodion--a solution of gun-cotton in ether--which is found to be peculiarly suitable for the reception of the sensitive preparation of silver. Frederick C. Bakewell. Great Facts.
• In conducting the collodion process, the collodion is first iodised by adding to it iodide of potassium and iodide of silver, dissolved in alcohol. Frederick C. Bakewell. Great Facts.
• The pictures produced by the collodion process are negatives, which serve admirably for transferring positive pictures on to sensitive paper. Frederick C. Bakewell. Great Facts.
• In his method of doing so, he covers the steel plate with a solution of isinglass and bichromate of potass, and placing a collodion negative picture upon it, he exposes it to the action of light. Frederick C. Bakewell. Great Facts.
