ArtGraf is a tablet of watersoluble graphite in a tin.
While there are a few watersoluble graphite pencils and crayons on the market, this is the first larger format offering aimed at brush users that I’m aware of.
Viarco, a small Portuguese pencil company that we’ve mentioned once before, introduced ArtGraf last year.
The product extends watersoluble graphite possibilities, and truly allows painting in graphite. A wet brush is applied to the tablet. Varying the brush wetness and tablet contact result in varying graphite densities.
I truly think this is a great product.
