R&F Encaustic - soy wax - 453g bag

Soy wax (actually partially hydrogenated soybean oil) is an excellent alternative to paraffin for cleaning brushes for several reasons.
Soy beans are a renewable resource, unlike paraffin, which is a petroleum product.
Soy wax is non-toxic and is naturally biodegradable.
Soy wax is also easier to remove than paraffin wax, so after the color has been cleaned out of the brush, the brush can be washed with soap and water and is reusable in other mediums.
