What is liquid pencil?
Have you ever been sketching and wanted to cover a larger area quickly?
Or wanted to variegate the tone very subtly, similar to using a
watercolour? Well, Derivan Liquid Pencil is capable of all these things
and more. It's a truly revolutionary way to create sketches.
Derivan Liquid Pencil
Derivan Liquid Pencil is available in Permanent and Rewettable formulas
in six subtle graphite shades - Yellow, Red, Blue, Sepia, Grey 3 and
Grey 9 in 12ml tubes.
All shades in the Derivan Liquid Pencil range were created using
natural graphite powder, just like those used in the more familiar
solid form and most commonly known as the active ingredient in lead
pencils.
Graphite is a common, naturally occurring form of carbon, non-toxic.
When carbon compounds are subjected to extreme pressure and heat, it
converts to crystalline graphite.However, not all graphites are equal.
There are different types of natural graphite, each sourced from
different types of ore deposits and each intended for a variety of uses
like, lubricants, batteries, household and automobile paints and, of
course, as artist medium. Graphite in various grades of softness or
hardness results in different qualities and tones when used in artist
media.
Different regions on the planet produce graphite with unique
properties. For example, the graphite powder used in Liquid Pencil Grey
3 is sourced from China and has a partially formed structure that
contains additional compounds, which give it a deep black colour with a
blue undertone. In contrast, the graphite used in Liquid Pencil Grey 9
comes from Sri Lanka and has a more uniform chemical structure that
imparts a silver metallic sheen to the finish.
How to Use Derivan Liquid Pencil
Derivan Liquid Pencil is an innovative new product that allows you to
create authentic graphite pencil effects and sketches using a liquid.
It has been formulated so you can thin it with water or MM9 Acrylic
Painting Medium (to maintain permanency).
Derivan Liquid Pencil has a creamy consistency and different rheology
(flow of liquid matter). Artists now have a broader 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 efficiently, and the
addition of MM9 Medium will maintain the intrinsic structure of the
product
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 will not smudge.
The Rewettable formula will also allow you to remove areas using water
– similar to watercolour techniques. A standard eraser can also be
used, and while it will remove some of the graphite, it will not erase
back to clean paper. Another advantage of using Derivan Liquid Pencil
is that large areas can be easily built up and covered. This product
can also is entirely compatible with the traditional solid form of
graphite.
Each shade variation 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 indicates the final rendered layer's undertone
(cooler or warmer grey ) rather than lightness or darkness.
Derivan Liquid Pencil Clean Up
Brushes, utensils, and hands can then be washed with soap and water.
Wash stains out immediately with cold water and household soap, taking
care not to spread the stain. Dry stains will need to be soaked
overnight in lukewarm soapy water. Do not use hot water, chemical
solvents, or thinners. Other cleaning methods will generally only act
to drive the stain in deeper.
Suitable clothing should be worn as some staining may occur.
Derivan Liquid Pencil is a non-toxic water-based product containing
water and graphite powder dispersed in an acrylic polymer
emulsion. Please view or download the Safety Data Sheet document
