Product Information

Cass Art, Cass Art London and the Cass Art logo are trade marks and trade names of Art-Line Limited. This pencil is usually made from non-toxic opaque wax (such as paraffin, beeswax, ceresin, carnauba or spermaceti wax) [1] that is similar to a crayon but stronger.

No matter what you use a pencil for - for drawing or writing - a sharp lead is required at all times. The original and leading marker pencil for marking on glass, china, acetate, film and polished surfaces. They may also be used to mark wood, brick and metal, making them extremely popular amongst tradesmen, as well as crafters and artists. In the days when broadcast studios had a library of LP records, a track which was prohibited from public performance could be defaced by a wavy white or yellow chinagraph line, giving a visible warning to the presenter as well as making that track unusable. As the lead is still very soft and bendy at this point, it has to be baked in the oven at a very high temperature.However, there are further differentiations in the hardness grades H and B, which are determined by a number placed in front of the letter. Our high-quality pencil accessories sharpen your pencils in an instant and help you achieve optimum writing and drawing results. The outer casing may be made of wood (like an ordinary pencil) and sharpened with a knife or pencil sharpener. Grease pencils were also widely used during the mid-20th century in aircraft control centers, military radar defense system stations on land and in aircraft carriers in particular.

The clay acts as a binding agent and gives the lead its shape and strength, while graphite produces the characteristic silvery black colour on the page. For perfect writing and drawing results, you not only need high-quality pencils, but also the right accessories. Surfaces used with grease pencils include glass, rock, polished stone, plastic, ceramics, acetate, and other glazed, lacquered or polished surfaces, and metal, as well as the glossy paper that is used for photographic printing (particularly for contact sheets), x-rays, maps, and for marking edits on analog audio tape and film. The West Chinagraph Pencil is the original writing instrument for use on glass, acetate, film, china and other polished surfaces.These Chinagraph Pencils are p erfect for writing or drawing on most surfaces, including glass, china and acetate.
