Derwent Inktense Blocks are highly versatile water-soluble blocks which create vivid inkline colour when combined with water. Highly pigmented dry colour transforms into pure, translucent ink-like wash which is permanent once dry. Due to its permanence, Inktense can be worked over without affecting previous layers of vivid colour. Suitable for use on paper and fabrics for a wide range of fine art and craft projects. Intense Blocks are available in a range of 72 colours and are ideal for creating larger areas of colour and expressive mark making.
