Pens and Pencils

Drawing Pencil	Pencil leads are graded according to their ‘hardness’ (H) and ‘blackness’ (B) by varying the mix of Graphite and Clay - a 2H pencil is useful for Technical Drawing, HB is the common writing grade and a 2B pencil is good for shading pencil sketches. The body of good quality pencils is made of Cedar and this can be indentified by the distinctive scent released when the pencil is sharpened. Note: Always try to use a full length pencil for best control when drawing or sketching and keep it sharpened.
[https://en.wikipedia.org/wiki/Pencil Coloured Pencils (aka Pencil Crayons);;	Unlike the leads in Drawing Pencils the core of these is based on wax mixed with Pigments to provide the required colour. Activity: Try shading in a sketch using a 2B Drawing Pencil for example then go over it again with light shading using a coloured pencil to create an easily achievable presentation sketch (when shading, hold the pencils well back and use light strokes in one direction only) Note: The Snowman by Raymond Briggs was illustrated using Coloured Pencils.
