Mixing Powdered Dyes

If you come across old (before 1950) dye sets, these directions may assist you in mixing them.

Eastman dyes:

If these are the big tubes, then mix 30 grams of powder in 5 litres of water. Use the directions posted here, just this week. Add 5ml of formalin to 500ml of dye.

normal contrast

  • cyan dye: 10 ml acetic acid (5%) into 500 ml dye solution
  • magenta dye: 10 ml acetic acid (5%) into 500 ml dye solution
  • yellow dye: 15 ml acetic acid (5%) into 500 ml dye solution

lower contrast

Use half the acetic acid, ie, cyan: use 5ml acid

higher contrast

Increase the acetic acid by 50%.

Dytrol dyes

Follow the directions for the Eastman dyes, but exclude the formalin (preservative) since the Condax Dytrol dyes contain a perservative in the powdered dye.

Normal contrast

Use 3ml acetic acid(28%) per litre

Orthotone dye

Orthotone is supplied was a concentrated solution which was to be diluted, 20ml dye to 600 ml water. Formalin should added to the mixed dye. Use the Eastman formalin mix instructions.
