Derivan Liquid Pencil is available in six graphite shades each with a permanent or rewettable formula. Each of the shades have a definite graphite colour, however, there are distinct undertones such as blue, yellow red, sepia and neutral in two different strengths to allow a great range of options for artists.
Derivan Liquid Pencil is an innovative product that allows you to create authentic graphite pencil effects and pencil sketches using a liquid. It has been formulated to be easily thinned with water or MM9 Acrylic Painting Medium (to maintain permanency) and allow for the softest of colours to be applied with a brush nib, or other art tools. With a creamy consistency, and a different rheology (flow of liquid matter), artists now have a wider scope for creating sketches.
Lighter or darker results can be obtained by mixing in a combination of water and medium and the effective layering (glazing) of different shades. Water will allow you to spread it more easily and the addition of MM9 Medium will maintain the intrinsic structure of the product.
As with all creative undertaking, experimentation is recommended as there are no precise 'fool proof' method to achieve exact variety of tones.
Due to a precisely balanced formulation another great benefit of the Permanent liquid pencil is that it will “burnish up’ in a similar manner to traditional graphite but it will not smudge.
The Rewettable formula will also allow you to remove areas using water – in a similar manner to watercolour techniques. A standard eraser can also be used and while it will remove some of the colour it will not erase back to clean paper. Another advantage to using Derivan Liquid Pencil is that large areas can be built up and covered quickly and easily. This product can is also completely compatible with traditional solid form of graphite.
Each of the shade variations gives each colour in the Derivan Liquid Pencil range unique properties. There are distinct undertones such as blue, yellow, red, and sepia, in addition to neutral grey in two different finishes - to allow a great range of options for artists – Grey 3 and Grey 9. The number is indicative of the final rendered layer’s undertone (cooler or warmer grey ) rather than lightness or darkness.
