Use of crocian scarlet to spot negs : LUSENET : Large format photography : One Thread

Dick Arentz mentions using crocian scarlet (spelling?) to spot negs in his book on Platinum printing. I had never heard of it before, but then saw and bought some at a store over the weekend. The entire sum of Kodak's included instructions for the use of this chemical, sold in dry form, was "Don't eat it." While this seems a sound basis on which to build, it's somewhat less in the way of user support than I might have hoped for. What sort of dilution does one tend to start with? Any special hints/concerns/issues? Anything special about using it for Platinum versus silver (I'll be using it on negs for both)? Can it be washed off easily if I overdo it? Toxicity (if not deliberately ingested straight from the bottle)?

Thanks in advance for your help!

Get a hold of Looten's On Photographic Enlarging for the definite before-we-had Photoshop take on crocian scarlet!

Second that Looten's -- He looks like Danny Kaye, but he made me almost want to buy a bottle -- well 6 bottles, but I'm too clumsy. Dean
