Derwent Inktense Blocks are highly pigmented, intensely vibrant, water soluble colour blocks that are permanent when fully dry to an ink-like effect. Experiment with different techniques to add some fun vibrancy to your fine art piece or use in unconventional ways to add some magic to your crafting projects. Using the active colour technology and advanced performance formulation found in Inktense pencils, these blocks allow for a more versatile application. Grate, shave, scrape, spritz, crumble or shape your blocks to achieve a myriad of effects. Use flat for broad expressive lines and fuller coverage or use the corners for more precise colour placement. Mix with water and see your artwork transform.

Unlike traditional watercolour, Derwent Inktense blocks have been uniquely formulated in vivid ink-like colours, offering exceptional layering capability without moving previously dried layers. Inktense can also be used on more than just paper; due to the staining power of the pigments, you can use the blocks on many porous surfaces including canvas, ceramic, wood and fabric.

Inktense blocks combine the brilliant colours of Inktense pencils with the freedom of blocks making it easy to cover large areas quickly. You can use these watercolour blocks dry or dip into the water to create deep, intense colour washes.

Derwent uses the Blue Wool Scale (ISO 105) to evaluate lightfastness. Lightfastness refers to the chemical stability of a pigment under long exposure to light. A
scale of 1-8 is obtained, with values of 6 or higher being considered to be highly lightfast and, under museum conditions, will not fade for 100+ years
