Arches Aquarelle is a top quality watercolour paper made from 100% cotton. Traditional mould-made manufacturing techniques in France make the paper harmonious with a natural grain similar to handmade paper. The cotton fibres are equally distributed throughout the paper block, making it more stable so the paper loosens uniformly when wet. Due to these techniques the paper has long fibres that gives it strength and produces an attractive, natural lasting whiteness along with a beautiful texture. The paper itself measures 18cm by 26cm that has a weight of 300gsm. Unique gelatin stock-sizing techniques are employed that are used on all Arches watercolour blocks, giving the ability to withstand scraping and shows colours at their most vibrant whilst being able to absorb a large amount of water with little deformation. Each of the 20 sheets included are naturally white and resistant to mould, with no optical brightener additives giving optimal longevity to the surface. The block has a rough and uneven surface which works fantastic with watercolour, and is glued on all 4 sides which is supported with a strong backing. - Brand: Arches - Size: 18cm x 26cm - 20 sheets - Rough surface - 300gsm - Colour: Natural White - Made from 100% cotton - Made in France - Natural grain similar to handmade paper - Mould resistant and acid-free for limited aging and increased longevity of the paper
