Kit containing two bottles of cyanotype mixes: (A) potassium ferricyanide and (B) ferric ammonium citrate. The products are sent in powder form. The end customer only has to add the appropriate amount of water to the bottles to obtain their ready-to-use products. The kit contains: - 1 bottle of powdered product (A) in a 200 mL bottle - 1 bottle of product (B) powder in a 200 mL bottle - 1 leaflet - 1 opaque cardboard box. These products make it possible to create approximately 400 cyanotypes in A4 format on thick paper. (Paper not included) Cyanotype is a fun and creative technique that is well suited to adults and accompanied children from around 7 years old. Cyanotype products are not toxic, but as with all chemicals they should be handled with some care, so a leaflet is included.
