Sandy,
Congratulations on your first kallitype. Nice process, isn't it? I would
like to make one suggestion. In the future, add a clearing step after the
developer. Like platinum or palladium printing the excess ferrous compounds
need to be removed. Rinse the developed print for one minute in running
water. Clear the print for a couple minutes in a bath of citric acid or EDTA
with constant agitation. The recipe for the clearing bath is a couple of
tablespoons full of either citric acid or EDTA in a liter of water at room
temperture. Then follow by a minute rinse in running water. Tone and fix as
usual.
Joe

> 1/2 step of density during toning.
> 7. Washed print for 1.0 minutes in running water.
> 8. Fixed print for 5.0 minutes in a 2.5% sodium thiosulfate solution.
> The print lost no more density during fixing.
> 9. Washed print for 2.0 minutes in running water.
> 10. Cleared print for 2.0 minutes in a 3% EDTA solution.
> 11. Washed print for 10 minutes.
> 12. Dryed.
>
> Result: Density of print close to perfect. Good deep rich shadows.
> Neutral gray/black color.
