KELLERBURSTEN BRUSH INFORMATION

Wood

Brush and broom heads are traditionally made from wood, mostly beech. For high-quality fine brush models, rare woods such as pear, maple, ash and olive are used. All woods are first air dried over several months and then placed in a drying room to reduce the final moisture content. Wood-stain, wax or oil is applied to give the surface fine finishing and protection.

Thermowood

Thermally modified timber (TMT) is wood treated at high temperatures, and this process changes its characteristics in such a way that it is sometimes describes as "domestic tropical timber".

This smoky, slightly rougher surface, results from a specific heat and pressure being applied to the wood to ensure consistent colouring throughout, creating an eye-catching effect. It creates new characteristics, such as reduced water absorption, longer durability, resistance against fungi and insects.

Explaining fibres & hair

Horse hair

This is the dressed hair from the tail (stiff) or mane (soft) of the horse. The hair quality is dependent on the breed, climate, season and condition of the animal.

Goats hair

This derives rom the Chinese long-haired goat. This extremely fine and silky soft hair is particularly suited for use in baby, face and other cosmetic brushes. Due to its excellent dust retention, the material is also used in various other brush types e.g dusters. To remove dust from the brush, pass a fine metal comb through the hair or gently rinse it in hand warm soapy water.

Coco fibre

Coco is harvested from the husk of the cocos nucifera palm coconut. The fibres are stripped from the outside of the nut and undergo an involved process known as 'retting'. Coco fibre can be up to 300mm long and is characterised by its toughness, its naturally resistant and lightweight. 

Natural bristles

The bristles are light coloured or naturally black. The longer the bristles, the firmer they are, and also more expensive.

Arenga

Or gumati is a palm leaf fibre that is produced mainly from the leaves of the sugar palm. Its colour can range from dark grey to blue-black. Its finer and softer than other palm fibres and yet tough and elastic.

Tampico

The yellow leaf fibre of the agave cactus. This is a very robust fibre, resistant to acid and alkakline solutions and to heat. Good elasticity and optimum water absorption make the fibre suitable for many applications, including household, massage and nail brushes.
