[pure-silver] Re: Kodachrome

Hello Myron,
One can develop to a negative with ordinary b&w chemicals, but the CLS (Carey Lea Silver) layer will remain, which is difficult, but possible to print through. Kodachrome develops quite well in b&w reversal chemicals. The only unusual chemical in reversal is the bleach (if you re-expose) which is either permanganate or dichromate in sulphuric acid. The CLS layer is removed in the bleach step. I have used both. It is not difficult. They both work well. I prefer dichromate. Of course there is always Dwayne's if you want colour. 

Cheers,
Clarence

A simple search of the archives didn't turn up anything, although I seem to remember this being discussed in the past:
Can Kodachrome be developed to produce a usable monochrome image by means of any more-or-less ordinary b&w chemistry?
I have a few rolls of exposed 120 in the freezer (and a few unexposed ones as well).
