Cyanotype- Brown & Brown Black Toners

Brown-Black Toner for Cyanotype  (1)

Solution A   1 teaspoon tannic acid in one liter of water.

Solution B    2 teaspoons of sodium carbonate in one liter of water.

Immurse print dry or presoaked, but not just right out of wash water from being made, into solution A for about two minutes.

Wash in clear water for about a minute.

Immurse in solution B for less than a minute and rinse again.

Put the print in solution A again and watch carefuly. Remove it BEFORE it gets to the color you want.

Wash.

Brown-Black Toner for Cyanotype (2)

Place dry print in Ammonia solution ( 12.6 ml per liter)

When bleached, place in Tannic Acid bath (23 gm per liter of water)

Wash

I have tried the first method and found that it works well.

Let me know how it works for you.

Best wishes,

Bob Schramm
