How-to Cyanotype: Supplier Links

For those of you eager to try out cyanotype printing yourself, here are some links to online suppliers of cyanotype kits, bulk chemicals, and precoated fabric

An Important Note: Original Cyanotype vs. “New” Cyanotype
There are two variants of cyanotype kits available:
1. Classic cyanotype / original cyanotype
2. New cyanotype / cyanotype II (as developed by Mike Ware)

What you want is the classic or original cyanotype as it is both cheaper and less toxic. It is what I use for all my printing and what I demo’d at Maker Faire. Although if you’re curious, the new cyanotype will work on fabric as well.

Sources for Cyanotype Kits
A kit is the easiest way to get started. My favorite kit is:
Photographers’ Formulary Original Cyanotype Printing Kit ($20)
- contains all the chemistry, conveniently premeasured in two brown bottles for proper storage
- full instructions
- kit makes a total of 500mL of sensitizer (250mL of solution A and solution B)
- enough to coat 2-4 yards of fabric depending on type
- Available as a liquid kit, premixed and ready to use
- Also available as a dry kit. The premeasured dry chemicals are already in the bottles and all you have to do is add water. (saves money on shipping)

This kit is available at several photo supply retailers including:
Photographers’ Formulary
B&H Photo Video
Your local photo supply shop (possibly)

Bulk Chemicals
If you start to do cyanotype printing on a large scale, you will want to buy your chemistry in bulk which is much cheaper than by the kits. The two chemicals you need are potassium ferricyanide and ferric ammonium citrate (green type).
I recommend comparing prices at:
Bostick & Sullivan

Precoated Fabric (ready to print)
Another alternative is to buy fabric that has already been coated with cyanotype sensitizer. This is much more expensive than coating your own fabric and limits your fabric choices, but is a good option if you don’t want to have to deal with the chemistry and coating process.

Other Supplies
Photo supply stores are also a good place to pick up additional supplies such as measuring cups, trays, gloves, apron, goggles, etc. You may have many of these items already around the house, but remember that once you use them for cyanotype they should be labeled and not used for food preparation again.
