|Drawing Pencil|| Pencil leads are graded according to their ‘hardness’ (H) and ‘blackness’ (B) by varying the mix of Clay and Graphite - 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.
Features and Applications
|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 (or ‘blacker’) 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)
|Carpenter's Pencil|| These flat, rectangular pencils have bodies which provides a for strong grip. The strong and larger lead can withstand being used on rough surfaces and their shape enables them to be sharpened to a more durable knife edge instead of just a point. Because of their rectangular shape these pencils are usually sharpened with a knife although specialised Pencil Sharpeners are available.
Safety Point! When using a Knife always push the knife away from yourself and take small shavings at a time.
|Felt Tipped Pens and Markers||These are available in a wide range of colours as erasable and permanent markers. Special purpose variants include: highlighter pens, security markers and pens suitable for writing on shiny surfaces such as CDs or DVDs. Designers may use high quality markers, available in the Pantone range of colours, to hand render presentation sketches and final designs (although much of this work is now done using computers).|
