Derwent Inktense Block Sepia Ink Pack of 6

Unlike traditional watercolour, Inktense pigment dries permanently once water evaporates. This means you can apply additional layers, glazes, or other media on top without reactivating or lifting the colour beneath - a significant advantage for complex, multi-layer artwork.

Yes. Derwent Inktense Blocks are suitable for use on natural fabrics including silk and cotton. Once the colour is applied and fixed, it remains stable. Always test on a scrap piece of fabric first, and follow any specific fixing instructions recommended for your textile project.

The blocks work both dry and wet. Used dry, they deliver smooth, intense pigment similar to a soft pastel or block crayon. Activated with water, the pigment flows as a vivid, ink-like wash. Both methods are valid, and artists often combine them in a single piece.

A single-colour multi-pack is practical for artists working on larger pieces, teaching groups, or extended projects where running out mid-work would disrupt colour consistency. Having six blocks on hand means you can work freely without rationing pigment.

Derwent recommends Inktense products for artists aged 14 and above, including advanced students, serious hobbyists, and professional artists. Younger children or complete beginners may find the Derwent Academy range a more appropriate starting point.
