Saunders Waterford is an exquisite watercolour paper, traditionally made on a cylinder mould machine. This is the superior quality watercolour paper made by St Cuthberts Mill and comes with the Royal Watercolour Society’s endorsement. Made using 100% cotton, the highest quality paper-making material, to high archival standards. Each sheet is buffered with calcium carbonate to help defend finished pieces of work from discolouration caused by acids present in atmospheric pollution. Its attractive surface is created using natural woollen felts that give it a distinctive random texture. The surface is sized in gelatine making it strong and resilient to scrubbing, and other rough treatments. Available in White and High White, which may well be the whitest archival watercolour paper made. Saunders Waterford is a top quality professional watercolour paper. Saunders Waterford papers are also available in blocks of 300 g/m² (140lb) watercolor papers in HP – Hot Pressed, CP Cold Pressed or Not Hot Pressed (NOT) and Rough surfaces. Each block is glued on all 4 edges, keeping the paper tight when you apply a wash. When using a block you do not need to go through the process of soaking and stretching the sheet as the block does this for you, and the paper dries flat. Blocks are excellent for painting on location. Once the finished painting is dry, you remove the sheet by carefully placing a blunt paper knife in the small unglued area in the spine, carefully sliding the knife around the block. Each block contains 20 sheets of 300g/m² Saunders Waterford paper.
