**Ready to Use Collodion ages on the shelf regardless if it is being used or even opened**
We mix Ready to Use Collodion upon ordering to ensure the longest shelf life for the salted collodion. Ready to Use Collodion will continue to age once mixed and continues too regardless if the bottle has been opened or in use. The older the collodion the slower it is. If you are not shooting immediately we recommend buying the two part kit and mix it yourself to avoid over aged collodion.
Cadmium-free collodion is considered a safer alternative for classrooms and workshops, as well as those who are on a septic system. Similar in speed to our Old Workhorse formula.
