What is the difference between the pencil ranges?

More questions

How did Derwent decide on the pencil livery?The stained barrels were chosen mainly for environmental reasons. The UV coating process is environmentally friendly and stains are the ideal finish for UV coating. The angled dips were chosen as a design feature to make the pencils stand out and have their own Derwent identity.

What gives a pencil its texture?
All the ingredients play a part. High levels of pigment will tend to make a pencil hard. The amount and type of wax will define how it interacts with the paper.

What is lightfastness? 
A measure of how quickly something will change when exposed to UV light (sunlight). Light can cause colour to whiten, darken, fade or completely disappear. Lightfastness refers to the chemical stability of a pigment under long exposure to light. Our colours are rated on a scale of 1 to 8, the higher the number the better lightfast rating it has, so a colour with a rating of 8 will react more slowly when exposed to light.

What's the difference between the graphite degrees?
B stands for BLACK and H stands for HARD. 9B is very soft & black and 9H is very hard & pale in shade. HB is half way between the two. F degree was made (stands for FINE) for doing shorthand in the days before computers!

How are degrees made and controlled?
By varying the proportions of clay and graphite. More graphite means a softer, blacker degree. More clay means a harder degree. HB has 50:50 clay and graphite.

My pastel pencil won’t sharpen, it keeps breaking.
Pastels are more delicate than normal pencils so they need to be handled with care during sharpening. Also the materials used to make pastel pencils are more abrasive than the materials in other pencils so the blades in sharpeners and craft knives will blunt more quickly. We recommend using a craft knife or special pastel sharpener and replacing them regularly to keep the blades sharp.

How can we identify when a particular batch of pencils was made?
Each batch has a date code stamped on next to the imprint. This identifies the week that batch was made. From that we can trace the exact details of when the pencils were manufactured: the day, the operator, the machine etc.

Can Derwent products be used by vegans?
