Description
Lead acetate is used as a toner in cyanotypes. Like many other lead compounds, it is toxic. Lead acetate is soluble in water . A processed cyanotype is immersed in a 5% solution of lead(II) acetate which shifts the blue towards a beautiful deep violet. Cyanotypes toned in lead acetate show improved resistance to light fading, by a factor of about four. Reference Mike Ware LINK
