 from the pot.


A product of the UK our Slate Dust is made from pure Slate. It is a very fine dust that is almost a powder .

It is grey in colour and gives a slight grey colouration to the wax mixture, it gives to the Cold Wax extra substance and allows marks to have greater thickness and texture.

It can also be added as a dry powder to the painting, this also gives texture to the work.

It does not have the 'gritty' feel of the Marble Dust and can be added to Gesso or PVA glue to give extra 'grip' to the surface for painting with Cold Wax. When applied to paper with either Gelatine, Gesso or PVA, gives a good surface with a 'soft tooth' very suited to Pastel and Oil Pastel work.

Like the Marble Dust it is basically an inert (chemically inactive) substance and has been in use for 100's of years.

How much do you add?
 Adding too much to the wax/oil will make the mixture dry and crumbly, if thus happens add more wax and oil paint.
Because every wax/oil mixture will be different, you will need to make your own decision about the quantity to add depending on your own requirements for the work.
It can darken wax/oil mixtures therefore does not suit everyone.
Can be useful as an addition to watercolour and mixed media work.

It is classed as a Non-Hazardous product, however, do be aware that it is a dusty material. It goes without saying - Always wash hands with soap and water after using any type of art product.

Sizes available - 150 gm; 300 gm.
