Jacquard Cyanotype Sensitizer Set

I used this type product a little over 40 years ago. Yes, 40. Back then a lab had to make kodalith negatives; now, just printers & transparencies are needed. I followed this exact process with this dry mix product. It was easy as long as you can put it together in a homemade dark room. Life happened, I thought these parts to a planned quilt were lost. They have resurfaced after all these years and look at them! The color has not faded.

prints were amazing! I will totally buy it again!

Fantastic results, very easy to use.

Works very well and is easy to use. The bottles contain the chemicals in powder form, to which you need to add water. That can be a little tricky since the bottles are opaque. Be careful not to overfill. You need to shake up the bottles and let them sit for a day or so so completely dissolve (according to instructions). They say the chemicals are pretty safe, but I used rubber gloves and Im sure theyd stain if you got any on you. I used watercolor paper and a wide soft brush. The paper was pretty absorbent, so it was not easy to get even coverage. I found that making long, fast strokes worked best to keep chemical from soaking in unevenly. A harder surface paper might be better. No idea how it would work on fabric. I poured a tablespoon of each chemical into a dish, which was enough to coat 8 sheets of 8 x 11 paper. They say this kit will make around 65 8 x 10 prints and I would guess youd get at least that if not more. I used transparency film negatives printed on my laser printer, but for really solid white areas on the print I think Ill be using a commercial copy shop to make the negatives. (You can also use a sharpie to draw directly on film, but remember that what you draw will be white on a cyan background.) I made a sandwich of my negative and paper between two sheets of picture glass, held together with small binder clips. Be sure to coat and store your unexposed paper and assemble your print frame in a darkened room . It seems more sensitive to ambient light than I expected. I tried various exposure times and found 5 minutes on a sunny day to be more than adequate. Adding just a cap full or less of hydrogen peroxide to the rinse water makes it develop its deep blue color almost instantly. Be sure to rinse the prints thoroughly. Any residual chemical will continue to darken.

Just as pictured. I mixed the solutions w water a few weeks before use and it still worked great. Gonna definitely buy again

This was great! Easy to use and provided a whole afternoon of fun for friends and family!

Love this product demonstrating how to use alternative photography processing... very unique!

A cheap alternative to Bostick and Sullivan brand. It works just as well but be warned you have to mix it yourself. Use distilled water and measure the amount and youll be fine.

Product easy to use...and having a great time producing cyanotypes on watercolor paper

Works great. Had some user error getting used to the process
