1l liter of wet plate developer: Ferrous sulfate, nitric acid and potassium nitrate. This developer wil produce images with a more controlled contrast and cooler, more metallic tones. It is recommended to add a few drops of the silver nitrate bath to the developer just before pouring it on to the plate if we want to increase the metallic effect of the developer

100g of pure silver nitrate.
Silver nitrate is used to sensitize wet collodion plates in 9% a solution.
Silver nitrate is a corrosive heavy metal salt and it can cause burns in contact with your skin or any other mucous membranes of your body. Handle carefully and wear gloves and goggles.
250ml of sandarac varnish. Sandarac is the most commonly used varnish for wet plate nowadays. This is the classical gum sandarac formula but filtered with activated carbon to lighten its color. The result is less darkening and a more similar color to the unvarnished plate.
The use of alcohol based varnishes is suitable for freshly made collodion. If your plate has been shot with an old collodion we recommend you to choose an acrylic varnish to prevent dissolving the image. You could also seal your plate with a glass dome and Canada Balsam.
Our varnishes are sold in borosilicate glass bottles, which are easy to clean and more resistant than regular glass to impact and temperature changes.
If you have trouble with this varnish dissolving your images, adding a few ml of distilled water to the varnish could solve this problem.
480ml of collodion. All of our collodion formulas are supplied inside wide-mouth borosilicate bottles to allow an easier pour and avoid the aging of the collodion as long as possible.
The Old Workhorse formula contains 2 salts: Potassium iodide and cadmium bromide. It has a great tonal range, similar to the Quick Clear and a long shelf life, but It’s one stop slower than Lea #7.
It is cloudy when mixed and needs between a week and a month to rinse and for impurities to precipitate to the bottom of the bottle. Decanting is necessary: you may want to buy a 500ml bottle for this purpose. It can be used shady without too much trouble.
All our collodions are freshly mixed when we receive an order.
