DIAZO Photo Emulsion + Sensitizer Set

Usually very good product but this time the sensitiser would not dissolve in the bottle. After attempting to get it all out and mixed with the emulsion I have ended up with a lumpy unusable product!, at over £50 this is not cheap. I brought two of these and am nervous about opening this. I need it for an art job. Perhaps it’s been in the ware house too long?

Good stuff.

I got this container of emulsion because a printer friend offered to teach me the basics of screen printing. This stuff works perfectly, but I am glad I had an experienced teacher. Spreading it to the correct thickness, exposing it correctly and then washing off the excess without blowing out details was a but tricky. I probably should have picked less detailed art to start, but I also probably learned more by using art I really do want to print. In any case, the only improvement I could suggest is to add a 1.5 oz measuring cup to measure the water for the sensitizer, but eyeballing did work. However, the shipping can be a nightmare as others have noted. My first order was shipped in an envelope with no protection for the thin Speedball box inside. The bottle was crushed and the emulsion had leaked. I could not even get the envelope open because it was one solid mass of emulsion. The replacement order was shipped in a box and arrived with no damage. Since the shipping was done by Amazon, I did not take off any stars from the product. I hope that Amazon addresses the packing issue because it is a great product once you get an intact set.

Seems decent. The emulsion seems old tho. Had to use cricut instead.

This is the second time I’ve tried speedball diazo, the first I assumed I had made some kind of mistake because it didn’t turn green. I realized this time that it was not my fault, the sensitizer clumps into a paste on the inside lip of the bottle and won’t come out, no matter how much water you use or how much you shake it up. I wound up trying to pick it out of the bottle to mix it in because I’d put so much water in that the jar was almost overflowing. No matter what it wouldn’t mix in. (Fun aside— it also stained my counter tops and my skin brown while I was trying to mix it together by hand, and the day after, I became violently ill and couldn’t keep any food down for two days. That “wear gloves” warning is a little small.) Very frustrating, I’ve used speedball for Lino printing supplies and I loved their stuff, but this is very disappointing.
