Derwent Inktense Colour Blocks are incredibly versatile sticks of vibrant watercolour ink. Use them dry for covering large areas, or add water to bring them to life. Once dry, the colours are fixed, allowing you to work over them without them dissolving. This permanency makes them ideal for use on various fabrics like silk, cotton, and canvas, and they are also suitable for printing and stamping. They offer many creative possibilities: use dry and blend with water using a brush, or apply water directly to the blocks. You can also place multiple blocks side-by-side before adding water to create instant stripes. Grate a block into water or shave off small pieces to create washes. Apply water to a block and shake it for paint splatter effects. These blocks are intensely vibrant and watersoluble, designed to dry permanently, providing excellent layering without dissolving previous layers. The highly-pigmented colours are permanent when dry, creating ink-like effects. Suitable for a wide range of fine art and craft projects, they can be applied to porous surfaces including ceramic, wood, and fabric, making them ideal for silk paintings and quilts.
