Potassium Dichromate is a water soluble chemical stain that reacts with the tannin in the wood
The oxidizing action replicates and accelerates natural aging and darkening associated with UV exposure. The results are rich tones, with clarity of the wood grain and pattern.
Traditionally Potassium Dichromate is used to darken Cherry, Mahogany, Oak or Walnut.

Preparation:
-- Mix in Plastic or Glass only.
Dissolve the Potassium Dichromate
•• 1 teaspoon in 8 Oz, of hot water
or
•• 4 oz by weight into 1 Qt .hot water (100g into 1L).

Test the result on a spare piece of wood.
The color can be darkened by adding more powder or lightened by adding water.

Directions:
Apply with the grain using a brush, rag or sponge.
Use two successive coats to help eliminate lap or streaks and
to assure a more even tone when dry. Wipe off any excess with a rag.
Pre-wetting the surface, just prior to application, will aide in even absorption of the Dichromate solution. Use Clean water and a damp (not dripping) sponge or rag.

Allow to dry at least 12 hours, then rub down lightly with a
fine synthetic pad or #0000 Steel Wool, before applying a finish.
Any finish can be used over the 'Dichromate stained' wood.
