Thanks for your incredibly thorough tutorial - currently have a cyanotype jelly cooling in my fridge. Have been having a tricky time with cyanotype on porcelain (was just using a gelatin sizing/subbing layer) giving inconsistent results so I’m going to try moving to your method and see if it will work for porcelain. I noted in your pdf you said don’t heat the gelatin above a very specific temp but in the tutorial you said until it’s ‘steaming’ - you just work by feel rather than with a thermometer? Mine seemed to reach the recommended temp before it was ‘steaming’. Also, was wondering how safe it really is to be heating ferricyanide? A respirator perhaps? Thanks again for an amazingly in depth tutorial and associated resources!
@JosephJMcAllister

I mainly work by feel, but I put a specific temperature in to try to help people who would rather work with temperatures. It should be approximately about the same as when it's about to steam. Heating ferricyanide is a bit of a concern but I've never had any problem with it. Putting a finished plate into a weak acid or potassium cyanide will release all the cyanide gas instantly. You will have a metalic smell/taste, feel a little light headed and my have tingling in the eyes, and fingers, and a sense of anxiety. I also make 5 gallon buckets of cyanotype and process 10 ft prints. So I have had several light exposures. Even in massive quanities the exposures have been minimal. But only when I make a mistake. Just dont add mild acids to it.

Mild Acids or Potassium Cyanide will break the molecular bonds of the ferric ferrocyanide very easily. You will see a clearing. The blue disappears and turns clear. This is how you know the cyanide has been released. Or a faint metallic taste/smell, lightheadedness, cold clammy hands, anxiety, shortness of breath, ear ringing, stars, tingeing in the eyes, fingers, chest, or nose. I've never seen clearing from heating the gelatin, or had any problems. I only heat it until a slight mist can been seen leaving the top of the gel as it's heating, never boil. This is most likely water vapor, and not a breakdown of the ferric ferrocyanide. Some small amount of cyanide gas may be released. I would recommend your dark room being at least the size of a duel car garage, or ventilated. An M3 painters respirator mask will remove 95% of these fumes if you are concerned. People are concerned with the various subtle exposures from Alt Process. But we are exposed to fumes and chemicals ever day. (Smog, fluoridated water, car exhaust, Acetone: (Paint, Varnish), Ether, Clorox, Ammonia: Windex, fiberglass insulation, plaster dust: Drywall, Chlorine, Alcohol, Tobacco, glycerin glycolic: Vape). To me, it's just being aware of the chemicals we are using, knowing the MSDS data, minimizing exposure, protective equipment: M3 Mask, Gloves, Safety Glasses, and accepting the risks of the chemicals you choose to be involved with. Good luck with your photography work. Joseph.

Hi Joseph, two months trying to make cyanotype on the glass in your recipe. But I have problems with the drying of the emulsion on the glass, it cracks and does not stick to the surface when washing with water at the last stage. No good grip. I tried to decrease with glass cleaner, but it did not help. At 12 minutes you talk about rottenstone glass, maybe the fact is that I do not use it. Maybe you could remember the analog of this substance? I live in Russia and wanted to find an analogy here. Thank you for the video and your time, Maria)
@JosephJMcAllister
5 жыл бұрын
I would never use Rottenstone cleaner for anything. The problem is not that the glass is dirty. It's the emulsion is going on to the plate too thick. When it dries it will crack and peel off the plate. Make sure the emulsion is steaming slightly with a subtle mist just before poor it onto the plate, then stand it vertically, and drain it as much as possible before drying it vertically. Only the thinnest coating will work.

Hello J.J. McAllister. This is a fantastic tutorial, thank you! I've made two emulsions now that have yielded some beautiful results. I have one question about timing; how long (even a ballpark) would you say you're exposing for with the tungsten lights please? I'm having a hard time nailing down exposure times using this method. PS - I also tried red chameleotyping, so COOL!
@JosephJMcAllister
5 жыл бұрын
Thanks. I use 500 watt tungsten Fresnel lights, focused tightly, at 3' ft from the plate, for 45 minutes. Some people use a light box at 1.5" in. for 45 min. In the summer, mid day, at 80-90 degrees, maybe 5 minutes. During the winder, mid day, could take all day. Visually, the plate starts green, then phases green and blue repeatedly as it builds up the density of the image until it is a dark blue. It's hard to gauge, so I usually do 8 at a time, expose, then switch off the light, and test one to see if they are ready. I don't get all 8. Maybe 4-6 turn out in a session. Maybe 2 are perfect.

I use glass from the $1 store. I just buy 8x10" frames and toss the junk plastic frame, which usually falls apart when I open the package. Then I debur the edge of the glass. Then wash the cutting oil off with a sponge and hand soap. The glass is 2mm (1/16") thick. I've never had any problems with it. I have never used any hardeners. The gel becomes stronger as it ages. Like 3 months. It's also stronger if your using a light source that heats it up a bit as it exposes, thus drying the gel. Too much heat will ruin it as well. You can try hardeners, but don't use formaldehyde. It fumes as you reheat it, and will poison you. It also may break down the ferric & cyanide bonds and release cyanide gas. For a harder emulsion, you may want to try auger, which has a higher bloom strength. I have never used it, but I know a guy that does. I don't know the ratios for auger. He doesn't seem interested in telling people his formula at this time.

Photographic grade cannot be removed form a plate for reuse, is why I don't use it.
