Brush manufactures use a blend of different natural bristles to change the softness and stiffness. These blends are Black China bristle, White China bristle and Ox hair brushes. All of these natural bristle types can be combined with each other or with synthetic filaments.

Black China Bristle Paint Brushes – Black China bristle brushes are perfect for use with oil base paint, primer and enamels. This type of natural bristle brush has the stiffness for cutting in a straight line and thicker hair for holding more paint.

White China Bristle Paint Brushes – White China bristle brushes is a great choice for varnishes, polyurethane and stains. White bristles are finer than Black China bristles and provide a finer finish. Watch out for cheap white bristle brushes. They fall apart very easily.

Ox Hair Blends – Clear wood finishes require a very soft brush for the best results and Ox hair blends are the softest, the perfect varnish brush. Usually a blend of Ox hair with white bristles, black bristles or synthetic filaments for stiffness.

These brushes cannot be used with latex paints or be cleaned with water this will ruin the brush! Never use a natural bristle brush in water or water based products. Natural bristle paint brushes absorb water and loose their shape, becoming imposable to control.
