For those people working with wet plate collodion and using KCN as fixer (please do not start debating on KCN, that is another thread/story) I have written up and attached a simple and cheap procedure to destroy your exhausted KCN fixer.

Included is a recipe for an indicator solution to test for free KCN.

It is not my finding although I tested it and wrote it up. Obviously I can not be held responsible.

Enjoy,

Cor

"Pour it into your neighbors pool..." ?!

Just kidding, thanks for providing this.

Which (the pool) will likely contain sodium hypochlorite (NaOCl) if they keep it sanitized.... ;-)
