After thinking about the following questions I set out to see if testing would help me sort out the differences between erasers. How it performed: Fine on light graphite lines and worst on coloured pencil. Fine on removing the graphite under pigment liner pens and didn’t lighten the ink. It didn’t remove too much watercolour paint but didn’t erase the graphite at all so was bad at that task. Charcoal has a considerably different chemical structure than Graphite, despite both being made from carbon. The make-up of charcoal is much more non-uniform and irregular. The structure folds in on itself, which gives charcoal its soft, crumbly texture. This structure not also makes charcoal a fantastic drawing tool, but also makes it suitable for other applications like filtering. How do you make Charcoal? As you build up your confidence using graphite and charcoal separately, you could move onto combining them both in a drawing. Using both materials alongside each other can create an interesting contrast between matte and reflective areas. 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

Faber Castell Green Dust-Free Eraser (‘dust-free’ means that crumbs clump together) (phthalate free) Channel graphite's restful energy into your bedroom with an upholstered headboard and knitted throw. Kidadl provides inspiration to entertain and educate your children. We recognise that not all activities and ideas are appropriate and suitable for all children and families or in all circumstances. Our recommended activities are based on age but these are a guide. We recommend that these ideas are used as inspiration, that ideas are undertaken with appropriate adult supervision, and that each adult uses their own discretion and knowledge of their children to consider the safety and suitability. When starting to colour, children often press down too hard as their sensitivity to pressure is not yet fully developed. These coloured pencils therefore also feature ABS, the white protective coating around the lead that increases break-resistance.

Phthalates are a chemical additive that makes plastic pliable (like a squeeze bottle) instead of hard (like the keys on your keyboard). There is more and more evidence that this chemical group affects the human body in negative ways as phthalates interrupt the hormonal system. Many brands of erasers have stopped using them. These plasticisers are in many plastics we use every day, I think they are of particular concern in rubbers because rubbers crumble and this must help expose more of the chemical to the air and skin.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.

Interesting fact no. 1: the original eraser was a squashed up piece of soft bread. You can still use bread if you don’t have a rubber, just pinch out the centre of a slice. Add 2 teaspoons of graphite powder to mixing container.Add a teaspoon of acrylic glaze.Mix thoroughly until it is completely uniform.Apply lid or transfer to airtight container.Follow the testing procedure below, revise your formula or methods and try again. Can you use graphite on wood? After reading about graphite and the color appearance it is composed of, you will also want to learn what color is bronze and what color is copper?

The exfoliation process for bulk graphite, which involves separating the carbon layers within graphite, has been extensively studied between 2012-2021. Specifically, ultrasonic and thermal exfoliation have been the two most popular approaches worldwide, with 4,267 and 2,579 patent families, respectively, significantly more than for either the chemical or electrochemical alternatives.
