Bockingford NOT surface. This paper is produced at St Cuthberts Mill in Somerset. It is a cylinder mould made paper producing a stable non-directional sheet to resist cockling and distortion when heavy washes are applied. Made from 100% photographic quality wood pulp, it is acid free and buffered with calcium carbonate to give long life properties unaffected by atmospheric acidity. Free from optical brighteners it is colour stable and will not change when exposed to light. Its economical price makes it particularly suitable for students in watercolour, drawing and printing. In white imperial sheets 56x76cm (22x30ins) 90lb, 140lb or 200lb.

It has an extremely forgiving paint surface allowing frequent changes to work. It is acid-free and buffered to protect from atmospheric contamination, internally sized, highly lightfast and colour stable. In white Imperial sheets 76x56mm (30x22ins) 140lb or 200lb.
