Sorts of Bristles and Hair Origin
Bristles

• Bristles are the hair extracted from pigs or boars, easily recognized by the split-ends. We define the origin from animals that protect themselves from weather changes through a layer of fat or the leather itself.
• With natural white color, bleached white or gray, they are very resistant and recommended for many sorts of painting. Due to the split-ends, the paintbrushes with bristles carry a larger amount of paint on the tip, allowing better efficiency to cover the surface. They are recommended for canvas and fabric surfaces, and also for painting the background on many materials.
• Special effects are obtained by exploring the bristles' texture, such as marked strokes, grooves, textures made with dough, patina, decape and other resources.
Hair

• Collected from animals that use the hair volume for protection from the weather changes. They are recognized by their cylindric shape and conic tips. The conic tip extension and the "belly" volume might vary according to the animal species.
• The paint concentration occurs at the bottom (root) of the hair, which we denominate "paintbrush inkwell".
• With this feature, we explore the tip for precise strokes and distinguished drawings, according to the brush shape.
• With many colors, they are recommended for use with many sorts of paint.
• Depending on the animal origin, they may be more or less flexible, and have different levels of thickness and porosity.
Pony: soft hair, smooth and very porous. Optimal paint retention in the paintbrush inkwell. Recommended for watery paints and softening strokes.
Ox ear: soft, flexible, resistant hair, with optimal precision on strokes. Selected and dyed, fulfills the needs of artists in many shapes. Recommended for many sorts of paint.
Marten: soft hair, flexible and with conic extended tip, defining the hair strokes with more precision. It has reddish color, and it's collected from the animal's tail due to the extension of the hair. Recommended for many kinds of paint, for illustrating and finishing.
Squirrel: Soft, flexible and very porous hair, with conic extended tip, allowing precise and continuous strokes. The color varies, it's collected from the animal's tail, where the longest hair is found. It retains a high amount of paint in the inkwell. Recommended for watery paints and smoothening strokes.
Synthetic Filaments

• Made of extremely thin nylon, they are resistant and flexible.
• They accompany the cylindrical shape of the hair with the conic tip.
• They are a great trend, stimulating the evolution of the water-based paints.
• Due to their composition, the synthetic filaments offer the possibility of distinguished shapes, more and more technical, as an answer to the artists' exigencies in the many painting styles.
• Recommended for water-based paints. Used in many different shapes, complements illustration and produces stroke effects, necessary for decorative painting.
Ferrule's Composition

• The ferrules are metallic belts that unite the tip to the handle. They can be made of polished aluminum, chromed or nickeled brass, nickeled steel, plastic and other materials. In the artisan paintbrushes we can still find ferrules made of feather binding.
• Usually, they have cylindrical shape with conic finishing at one of the ends, for the tip building and paintbrush number definition. The central structure of the paintbrush which defines the shape, anchoring the tip to the handle.
Handle Composition

• The handles can be made of wood, bamboo, acrylic, plastic and other materials. They are especially designed for a comfortable use.
• The raw material is previously treated to prevent deterioration.
• The handle's painted coat, in different colors, makes it easier to recognize the paintbrush families. The varnish enriches the handle and increases it's sealing.
• Through the printed data on the handle, we find information about the paintbrush composition, reference number, manufacturer and bar code.
• The handle defines the balance and stability of the paintbrush. It must be adequate to the ferrule and the amount of hair on the tip. It can be short, long or extra long.
• Short handles are recommended for painting at the eyes level, over a desk or in hands, when we need visual comfort for drawing details and precise strokes. Recommended for decorative painting, watercolor, porcelain, gouache and others.
• Long handles fulfill the needs of long and medium distance painting, the same perspective from which the artwork will be seen when ready. Example: canvas on easel.
• The extra long handles are recommended for larger artwork, murals, panels and others, facilitating the access to the surface. It's the same perspective from which the artwork will be seen when ready.
Paintbrush Number
With standard sizes in the market, the paintbrush numbers are printed on the handle.
The reading is done in centimeters or inches. On artistic paintbrushes, the centimeters measure is common. On wash brushes, the measure is frequently found in inches.
The tip of the ferrule which anchors the hair defines the number of the paintbrush through reading its diameter, on round brushes, and the width on flat brushes. The numeric grid starts at 0.
The numbers to the left decrease the brush size, and the numbers to the right increase it. Examples: 000, 00, 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24.
In the artistic paintbrush line, the most common sizes are from 000 (or 3/0) to 24.
