Mixing chems., & paper quest.greenspun.com : LUSENET : Black_and_White_Photography : One Thread |
1-Where can I buy chemicalas by bulk to mix myself? The only place that I have found so far is Artcraft. I'm in Canada, and I don't know where to look aside from "chemical supply houses". does anyone have any good recommendations? 2-I boguht 100 sheets of Agfa paper, MCP310 RC at 5x7. The paper was sipmle enough and I only had problems that were self-made. Now I have bought 100 sheets of the same paper in the 8x10 size and when I squeeze both sheets together I find that the 8x10 sheet is extremenly thin, much thinner then the 5x7. Whats going on? Nothing on the label, nothing I read, or expected...is it always like this? 3-Does anyone here use Pyrogallic Acid? 4-Can you recommend a COMPETENT, RELIABLE, MODERN book on mixing formulas made by scratch, a good/great cookbook? I'm trying to write as small as possible. Sorry if my questions are out of place. Thanks.

No apologies needed - this is the perfect place for your questions.Regarding the Agfa paper thickness discrepancy, is it possible that you bought the 8x10 in single weight and the 5x7 in double weight? I don't use Agfa myself but many papers come in different thicknesses (weights) but are otherwise "the same", though I don't see this as often with RC as with fiber papers.
A book that might fit your needs for chemical formulas is "The Darkroom Cookbook" by Stephen G. Anchell. Focal Press, 313 Washington St., Newton, MA, 02158. ISBN 0-240-80196-2, soft cover, $24.95. I haven't read the book, but a review in Shutterbug said it has 150 formulas, both modern and classic, as well as discussions on lab eqpt., conversion tables, percentage solutions, etc. The reviewer thought it was a must-have for B&W photographers (I don't have it...).
Another book that was reviewed was "The Book of Pyro" by Gordon Hutchings, Bitter Dog Press, Granite Bay, CA 95746, soft cover, 100 pp., $29.00. It supposedly gives info on both classic and modern versions/uses of this developer - mixing, fixing, toxicity etc. Again I haven't read the book but it might give you the info. you're looking for.
Good luck!
