Gray + Yellow. Charcoal and Graphite both bring different properties to your work. Beginners may find it useful to weigh up the pros and cons of using both drawing materials, before settling on one to start with. Charcoal Pros The ability to leave marks on paper and other objects gave graphite its name, given in 1789 by German mineralogist Abraham Gottlob Werner. It stems from γράφειν ("graphein"), meaning to write or draw in Ancient Greek. [9] [56] Wainwright, Alfred (2005). A Pictorial Guide to the Lakeland Fells, Western Fells. London: Frances Lincoln.

Using a craft knife you can cut a rubber into the size or shape you require for your drawing. Some artists prefer a sharp edge to their eraser.It is hard to erase graphite under a watercolour without damaging it. The best advice is to draw very faint lines you can barely see and when painted over they won’t show. Or let the graphite lines show a bit as part of the painting. If you are working solely with charcoal, try out as many types as possible to see what types of marks you can achieve with them. Using combinations of natural and compressed charcoals will allow you to explore a broader range of shades.

1. Lyra Graphite Sticks
As the name suggests, this is the ‘giant’ of the Milan family – the largest eraser of the collection. The eraser is made of soft synthetic rubber and it is suitable for removing strokes from graphite pencils on all kinds of surfaces. Because of its size (6.8 x 5.1 x 2.8 cm) we don’t recommend it for precision erasing. Koh-I-Noor Big Soft Elephant Eraser – natural rubber – oversized giant eraser, can be cut into many smaller erasers in the shapes you desire or makes a fun gift.

The watercolour pencils have a watercolour lead, which offers a wide range of colouring possibilities, as the rich colours can be applied with water and a brush. This range uses state of the art technology to provide unrivalled quality finishes from several of our main suppliers, a new range but one that is set to grow as individualism becomes ever more popular, designer doors, off the peg prices for doors that can provide high class finishes at reasonably low costs.

The sharpener revolves: it can be turned inwards so that it does not leak graphite dust through the blade aperture. To empty the pencil shavings from the (very small) reservoir, simply swing the sharpener outwards and pull it off the main unit. Is there a rubber that will remove a graphite line in a drawing without lightening the ink line on top? Faber Castell Perfection Pencil, Single Ended Eraser (soft for graphite, coloured pencils and charcoal) Expanded graphite is made by immersing natural flake graphite in a bath of chromic acid, then concentrated sulfuric acid, which forces the crystal lattice planes apart, thus expanding the graphite. The expanded graphite can be used to make graphite foil or used directly as a "hot top" compound to insulate molten metal in a ladle or red-hot steel ingots and decrease heat loss, or as firestops fitted around a fire door or in sheet metal collars surrounding plastic pipe (during a fire, the graphite expands and chars to resist fire penetration and spread), or to make high-performance gasket material for high-temperature use. After being made into graphite foil, the foil is machined and assembled into the bipolar plates in fuel cells.Graphite forms intercalation compounds with some metals and small molecules. In these compounds, the host molecule or atom gets "sandwiched" between the graphite layers, resulting in a type of compound with variable stoichiometry. A prominent example of an intercalation compound is potassium graphite, denoted by the formula KC 8. Some graphite intercalation compounds are superconductors. The highest transition temperature (by June 2009) T c = 11.5K is achieved in CaC 6, and it further increases under applied pressure (15.1K at 8GPa). [64] Graphite's ability to intercalate lithium ions without significant damage from swelling is what makes it the dominant anode material in lithium-ion batteries. Ingestion: Not relevant, due to the form of the product in its manufactured and shipped state. However, ingestion of dusts generated during working operations may cause nausea and vomiting.
