Blue Mountain Pottery was Canada's largest manufacturer of quality giftware pottery from 1947 until the plant closed for good December 2004. Located in Collingwood, Ontario, the uniqueness of Blue Mountain Pottery is a combination of the rich red clay, used in the moulding of the items, and the special glazing used to create the various shades of colour called "Reflowing Decorating". Collecting Blue Mountain Pottery is still popular by many and, as time goes on, will become much more difficult to find in perfect condition. All pieces that had a closed base had one of a variety of BMP mould marks. For items that had no base including most of the bird and animal items, they were sold with stickers or tags, many long since lost.
