The Journal of the Board of Arts and Manufactures for Upper Canada, July 1867
To some thick spirit varnish add a small quantity of iodine, sufficient to render the varnish of the requisite deep color. When a glass is warmed, and a coating of the varnish applied, it will be found to be beautifully transparent. In the case of a globe for a lamp or gas it should be warmed, and a little of the varnish poured in and turned round before a fire till properly covered.
