Walnut Crystals - Water Soluble Wood Dye Crystals

Regular price £3.00 £0.00

Made from crushed walnut husks and also known as Van Dyke Crystals.

Crystals dissolve easily in tap water.

This natural product is a traditional way to make a non-toxic, cost effective brown wood stain. Walnut Crystals can be mixed to any volume, so whether you want to stain an entire floor, a small piece of furniture or just cover some scratches, you can buy and mix the quantity to suit your needs. In its dry form Walnut Crystals  have an almost unlimited shelf life, if kept dry and in a dark place. 


Coverage is dependent on liquid volume and not weight of powder. Each 100ml of liquid covers approximately 1m square in a single coat. Absorbency of wood and application method will affect the coverage.

To Use:

Add just enough water to the crystals to dissolve them and make a very dark brown. Now add more water, a little at time until, the required depth of colour is achieved. Always test on the same wood as that which is being stained to get a good indication of the colour. The colour can be further altered by tinting the mixture with Bolger's Concentrated Water Based Wood Dye colours to make shades of oak, mahogany, pine etc.; water based liquid or powder wood dyes may also be used.  Seal surfaces with a minimum of two coats of finish of your choice. Once dissolved in water Walnut Crystals may also be used to tint products to which water may be added, like filler, grout and glue. 

Our image shows pine stained with 15g of walnut crystals dissolved in 250ml of tap water, and is for illustration purposes only, as minor discrepancies in measurements will result in shading issues. Always mix enough solution to complete a project (especially when adding a tint) and make a note of the ratios so the colour can be replicated for another project.

Interior use.
