Forms and shapes
For fine or larger strokes. The fine point means that it can be used
for detail work but it can also cover large surfaces dependent on
the brush size.
The choice of a brush is in part subjective, depending on the artists sensibilities, the diverse of the different types of component parts, different forms, dimensions and materials, all re sponding differently to precise criteria.
The handle gives a good grip on the brush and adaption with each type of painting. Traditionally painters brushes for oil and acrylic have long handles which facilitates vertical work and when standing back to view.
The fibres are selected for their specific physical properties: suppleness, liveliness, resistance, fineness and retention capacity.
Natural hairs from animals have a conical shape, with a rough surface. Sable hair is known for it's excellent liveliness, suppleness and exceptional retention capacity and is recommended for ink, watercolour and silk painting, also for works of great finesse in oil and acrylic. The Petit Gris is supple, silky with a good retention capacity and is recommended for watercolour and silk painting. For works with paste paint (oil and acrylic) a pure extra white bristle is preferred for it's firm and robust qualities and natural camber of the hairs. Pony hair brushes, more modest, is traditionally used by children for painting with guache.
Synthetic fibres are monofilament and conical fibres. They are lively with an average retention capacity they are also hard wearing and easily cleaned. They are ideal for oil and acrylic painting. Mixed fibre brushes give the specific qualities of natural hair with the resistance of synthetic fibres and can there for be used for many techniques.
