Hmm - I had Jaquard chemistry in pots mixed up the first batch probably 3/4 months ago - all good. Then I mixed up another batch from the same pots and when mixed it was going viridian which it hadn’t done before. It still worked but I do think the staining got worse. We had a heatwave and my...

Yes I have been using her book for reference. Seems in the U.K. the Jaquard chemistry is the most readily available. It’s working well. I’m kind of going one step at a time - started very amateur and am building on those basics adding acid development etc. it would be nice to lower my exposure...

Have you ever toned the Canson? Just wondering because I tried Arches Aquarelle HP and it soaked up botanical toning so badly that I rejected it outright because it went very stained. At least HPR stays relatively clean where there has been no sensitiser applied. Be interesting to know how...

Can I ask what dilutions of solution you are using (assuming classic cyanotype)? Previously I was just following Jaquard’s instructions on their tubs of chemistry but have realised it gives a very strong FAC solution which is over 20%. Quite possibly one of the contributing factors to staining...

Perfect, thank you! I have just recently started to neutralise my water with acetic, (too much of it and I got quite blue highlights) but I’ll get myself some citric acid. I’m going to experiment with Christina Andersen’s suggestion of a 10%|10% sensitiser, less FAC will hopefully help some way...

This morning I noticed a blocking density test that made about three days ago, it had another sheet of paper lying on top of it, which, when removed, left a white patch where other areas of ‘paper white’ had subsequently turned blue when left out in the light. This area had had a sheet of black...

Great reply - you have understood my dilemma perfectly. It’s very light blue residual solution that really stains bad when toning. I will try some red paper. Rubylith seems next to impossible to obtain in the U.K. and what’s available is crazy expensive for what it is. Also I noticed that using...

Hahn’ platinum rag which I assumed was kinda pretty good given that 99% of people seem to recommend for alt process.

Hi All, hopefully someone here will know something about my question: I have been trying out cyanotype using QTR and Quadtone Profiler DN - seem to have landed on an ink blocking density of K35 and have linearised a profile. I made a special blocking density file with no black lines between my...
