Rockland Blueprint Kit, 500ml

Product Description

Blueprints are blue images of photographs or drawings. They are a rich cyan blue, thus the name Cyanotypes. The chemicals used to make them, potassium ferricyanide and ferric ammonium citrate, are also the basis of the artist's colour Prussian blue.

This kit from Rockland works by painting a solution onto watercolour paper to create a homemade sensitised paper.

You simply lay clear plastic over a negative or a drawing; expose using sunlight, then running water is all that is needed to make it permanent.

Unlike emulsions, Blueprint saturates the paper or cloth it's applied to, so the amount of coverage varies greatly. But normally, an ounce will cover a square foot, so one pint (500 ml) will cover about 24 size 8x10 sheets..
