> M018 RWS 1987

For many years the RWS Imperial moulds were the most frequently used at Hayle Mill as this was the most popular handmade watercolour paper in the world from the 1950s to the 1980s. It was also the only one approved by the Royal Society of Painters in Watercolour. The moulds needed replacing every few years although they were then used for a longer period for less popular papers. This pair was made in 1986 by Ron MacDonald of Edwin Amies and son, possibly the last pair he made for Hayle Mill. Like most watercolour moulds this pair came with two deckles; one for Imperial 140lb and a lighter one for Imperial 90 lb and 72 lb although the latter weight was discontinued in the 1970s. The RWS watermark was introduced in 1975 and replaced the die stamp that used to be embossed in one corner. The BG logo was also introduced in 1975. Hayle Mill was one of the few mills putting the date in all its papers in the late 20th Century and we always made in clear that our papers were hand made.
