The Fibrecrafts Cyanotype Blue Printing Kit includes everything for experimenting with cyanotype: 200g ferric ammonium citrate, 100g potassium ferricyanide, 50cm x 90cm silk fabric, 50cm x 150cm cotton fabric and a detailed instruction leaflet. Create beautiful photograms, a heliographic sun light printing process, which produces a stunning blue print on fabrics and paper.
Our blog post Cyanotype Blue Printing includes a recipe for using these chemicals for creating cyanotype prints on natural fabrics, such as cotton and linen, and paper.
The Fibrecrafts Cyanotype Blue Printing Kit sold by George Weil contains 100g Potassium Ferricyanide and 200g Ferric Ammonium Citrate. Although the chemical names may sound alarming, they are relatively low in toxicity when handled correctly and are widely used for educational and artistic cyanotype printing. Potassium Ferricyanide is stable under normal cyanotype conditions but should never be mixed with strong acids, as this can release highly toxic hydrogen cyanide gas. As with all art and craft chemicals, sensible precautions should be taken: wear rubber gloves and safety goggles, and avoid inhaling chemical dusts when weighing powders.
