It has been formulated to so you can thin with water or MM9 Acrylic Painting Medium (to maintain permanency) You can create a wide variety of graphite shades. 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 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. Liquid pencil 12ml stand.jpg liquidpencil-img01.jpg 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. MORE GRAPHITE 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. 9PLP12SET-open01.jpg 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. CLEAN UP Brushes, utensils, and hands can then be washed with soap and water. REMOVING STAINS 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 methods of cleaning will generally only act to drive the stain in deeper. Suitable clothing should be worn as some staining may occur.
