Lyra Graphite Stick 9b

Product Information

Graphite pencils are made in different degrees of hardness by regulating the amount of clay added. The greater the quantity of clay, the harder the lead and the lighter the overall drawn line will appear. The grades available range from H (hard) to 9H (very hard). And B (soft) to 9B (extremely soft). HB and F are intermediate grades. Graphite is more durable and easier to transport than Charcoal, so would be easy to take out on drawing trips and classes.

Most pencils have some clay as well as graphite. The B indicates the proportion of graphite and clay. The higher the B number, the more graphite. When working from photographs make A4 print-outs so that you see all the detail – but don’t copy it all! Add to and subtract from the scene to make more drama. Remember why you took it in the first place. Evoke those feelings in your drawing. 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.

This will force you to focus on the essence of the composition and create freer, looser drawings filled with excitement.

Derwent Graphitone is a very stylish and pure graphite water-soluble pencil available in 2B, 4B, 6B and 8B. I find they dissolve better than other brands to create sumptuous passages of tone. Layering one tint over another is pure joy. Modern pencils are made by creating a paste of clay, purified graphite and water that is partially dried through a filtration process. This is then extruded and fired at 1038 degrees Celsius. These porous strands are then soaked and filled with wax allowing a smoother line and better adherence. These are the leads that are typically used in a pencil or a lead holder. 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 ProsUse an eraser wisely. There are no mistakes, only your thinking process. Enjoy your explorations and communicate what you see – let all your marks show. Graphite is an allotrope ( different structural form) of the element carbon. Although both Graphite and Charcoal are carbon based, the atomic structure of each varies quite dramatically. In graphite, carbon has a uniform arrangement, in distinct layers. Between these layers are very weak chemical bonds. As you draw, these weak bonds break allowing each layer to effortlessly leave the main graphite crystal. This property is how pencils glide so easily over your paper. They leave marks from tiny shards of graphite sheared from the main crystal. How do you make Graphite?

Compressed charcoal is made by mixing charcoal powder with grease and wax binders. It produces dark, bold marks that cannot easily be erased. It varies in texture according to the blend of charcoal, clay and fillers used.

Here are some hints and tips to help you get the most out of these mediums: Charcoal Pencils offer all the benefits of compressed charcoal, but with the convenience of a wooden case. Working in much the same way as a traditional pencil, charcoal pencils allow you to work with precision – without messy hands! Their wooden case means they are less likely to break, and they can be easily sharpened to a fine point. They’re fantastic for artists looking to try out charcoal, but who want some of the familiarity of a pencil. Tinted Charcoal |Graphite turns out to be an excellent conductor of heat and electricity, even in small quantities. In fact it's often used in motors. And because of its hexagonal molecular structure, graphite slides easily across other graphite molecules, making it an excellent dry lubricant. Graphite is found in artists' materials and pencils, in various ratios of graphite to clay (which binds it together); a 2H would have a higher clay content, while a 2B would have more graphite.

With the above in mind a hard lead makes sense. Worst case possible, a Triang/Hornby Nellie chassis, original clank clank motor.

Contents: The Chemical Structure of Charcoal and Graphite Everything You Need to Know about Charcoal How is Charcoal Made? What is Charcoal Types of Charcoal The first appearance of graphite encased in wood dates from around 1565, close to the time natural graphite was first discovered in Cumbria. Other natural sources exist in Siberia, Germany and in the USA. However graphite is now artificially produced by heating cokes (another carbon allotrope) at high temperatures.minipix wrote: ................as insulfrog points are connected up assuming the frog will be dead......................... Graphite Pencils are the most popular drawing and sketching tool. They have a wooden barrel which holds the graphite strip. This makes the graphite easy to control, sharpen and means you’re less likely to get messy hands. There are many ranges of graphite pencil available, with most offering a considerable range of grades. You can buy them both individually and in sets – sets are great for beginners, while individual pencils allow you to replace your favourites and tailor your collection to your specific needs. By combining different drawing media you can both draw and paint, keeping your options open and your work progressing in exciting directions. These ruins are in an area of the Pennines I know well and I never tire of them. Returning to the same motif is never boring – connections become deeper, drawings become stronger and emotional responses to the subject are all the better for it. Mechanical and Clutch Pencils are plastic and/or metal barrels into which you insert a graphite lead. You feed through the leads to the tip of the pencil by repeatedly pressing the button at the top of the barrel. If you’re working on a small scale then the precision tip of a pencil is more suitable for rendering small details.
