How would you describe the Derwent Inktense products? Chevron Icon

Inktense is a pigment-based product that is extremely soluble in water, but has a transparent ink-like wash unlike a traditional watercolour. Inktense is also permanent when dry.

Why should I buy Derwent’s Inktense pencils? Chevron Icon

Our Inktense pencils are great for layering, have vibrant and highly pigmented colours, which dissolve instantly and become permanent once wet (pigment needs to be fully dissolved in water then left to dry to become permanent). You can create transparent washes of colour, with dark and light tones depending on the amount of water and pigment used, but the Inktense Antique White is very opaque; great for highlights.

Is Derwent Inktense pencils wax or oil-based? Chevron Icon
Our Inktense pencils are wax-based.
What size is the Derwent Inktense pencil core? Chevron Icon

The Inktense pencil has a 4mm core with a round barrel.

How many colours are in the Derwent Inktense range? Chevron Icon

Derwent Inktense Pencils have 71 colours plus 1 outliner pencil. Derwent Inktense Blocks have 72 colours in total and the Derwent Paint Pan Sets have 24 colours between 2 Pan sets.

Are Derwent Inktense products dye based or pigment based? Chevron Icon

Inktense is pigment based but it's unique formulation produces vibrant colours and washes.

Are the Derwent Inktense pencils lightfast? Chevron Icon

87% of the range is lightfast, however once water is added, lightfastness ratings will be different depending on how much each colour is diluted. If you are looking to keep your Inktense art for as long as possible, we advise you keep your artwork out of direct sunlight.

Why do the Derwent Inktense Blocks and Derwent Inktense Pencils have different lightfast ratings? Chevron Icon

The blocks and pencils are made using different binders and wax blends, which will affect the lightfastness rating for each colour.

Is Derwent Inktense classed as an ink or watercolour product? Chevron Icon

It is classed as a watercolour product but it has different properties to a regular watercolour pencil, making it look like an ink.

Are Derwent's Inktense Pencils safe to use? Chevron Icon

Why is there a white pencil in the Derwent Inktense Pencil range? Chevron Icon

We have a white pencil, Inktense Antique White, in our Inktense range as it can be used to highlight your artwork or be used on black paper to really pop!

Why does the dipped end on my Derwent Inktense Pencil look a different colour to the pencil tip? Chevron Icon

The dipped ends are matched to the washed-out colour rather than the dry pencil core, so colours will slightly differ.

What is the Derwent Inktense Outliner pencil? Chevron Icon
The outliner pencil is a non-water-soluble pencil that can be used to create line and wash drawings.
Can a small child use Derwent Inktense Pencils? Chevron Icon
Derwent Inktense products are not recommended for use by children under the age of 14.
How do I use the Derwent Inktense ranges on fabric? Chevron Icon
To use on fabric, you do not need to put anything on the fabric beforehand. Simply apply the colour straight to the fabric and then dissolve the pigment with water. Inktense only becomes permanent if all colour is washed out fully and no remaining pencil/block/paint marks are left. Any remaining pencil marks will run.
Any washing should be done by hand, without any detergent or washing powder and should be done in a cool temperature such as 86 degrees Fahrenheit.  
Can you grate the Derwent Inktense Blocks? Chevron Icon

Can I use Derwent Inktense Pencils with my other Derwent pencils? Chevron Icon

Yes, Derwent’s Inktense Pencil range has been formulated to be compatible with other Derwent pencil ranges.

What sharpener should I use with Derwent Inktense pencils? Chevron Icon

Our Derwent Inktense Pencils works well with our Super Point range.

What are the wells in the Derwent Inktense blocks tray used for? Chevron Icon

The paint wells in all of our blocks tin can be used to mix the blocks with water to create an ink-like solution, adding to the versatility of this product.
