Take a teaspoon of powder from the jar, mix it with a little water in a plastic cup until a lump-free paste is formed.
Add more water to about 250 ml (a cup full).
Apply this liquid with a brush or spray with a spray bottle on the workpiece. During drying, the KC Bister can be wiped away with a dry cloth to create an overflow from dark to light. Varnish possibly with a layer of transparent KeraCoat.
KC Bister works like a patina and is particularly suitable for processing workpieces made on KC structure powders because it accentuates the edges and cracks and therefore gives the workpiece more depth.
