240ml of collodion (Quick Clear)
0 out of 5
37,00€
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 Quick Clear formula contains 2 salts: ammonium iodide and cadmium bromide. It has a great tonal range, similar to the Old Workhorse, but it’s one stop slower than Lea #7 and It also has a shorter shelf life.
This formula is completely clear when mixed. It could be used next day, even hours after mixing it, although we recommend letting it ripen for a week.
All our collodions are freshly mixed when we receive an order.
