240ml of collodion. All of our collodion formulas are supplied in 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.

This formula is cloudy when mixed. It will take at least a week to clear out. Although we recommend you to let it ripen and let the salts precipitate to the bottom of the bottle, it could be used before it’s completely clear. We also recommend you to buy a 250ml bottle to decant the solution.

All our collodions are freshly mixed when we receive an order.
