16oz Cyanotype Sensitizer Kit with 2 Droppers, Sponge Brush, Easy to Store Cyanotype Chemicals Dye Powder for Photographic Blueprints on Paper and Fabric, Sun Printing Kit for Beginners and Artists

Once mixed and painted, it goes on yellow and dries green. However, once properly cured in the sun, the product becomes a light to mid blue and after adding hydrogen peroxide, it becomes a dark blue. It is very tricky to use and time correctly using the sun as UV, but you it works and you get a lot of the solution if you’re doing a small project.

This was easy to use and had great results! It goes a long way too.

Easy to mix and very mobile. Keep it out of the sunlight and always use distilled water to make the solutions!!

Small bottles

Chemicals were either expired or contaminated. Solution came out dark blue, still tried it and it didn’t work at all. Waste of money and time. Just buy a better one that’s more expensive.

I love this cyanotype solution!! I used this during the entirety of my last printmaking semester and a little bit went a long way! I coated about 100 sheets of paper of various sizes with this solution to use for prints and I still had so much left over. I also used it on tote bags as well. Definitely would repurchase in the future.

I loved doing cyanotype prints when I was young and I want to try to do a shirt with it I was little confused by the packaging when I received it that the chemicals are dry and you need to add water to the bottles and let them sit ( which I think is great they cant leak during shipping) I read some other reviews that says you have to buy additional chemicals to use it do they mean "water" to mix and "hydrogen peroxide" to help develop the prints not sure what they mean cause the chemicals of the kit are dry in the bottles u mix with water then wait then u mix the 2 parts together paint on your substrate in a dark room let dry them to use you place items on the project and set in the direct sun for a while (best to do a test first to get the time right) and the rinse with water and hydrogen peroxide until the water is clear let dry there are a lot of videos on utube on how to do it

I bought an off brand and ...boy did I regret it. I use this for fabric quilts and I haven't been let down yet
