We have a very limited options of conservation quality mat boards in SA - I probably have 5 conservation quality (class 2) board options and 2 museum (class 1) board options, all in shades of white/cream. If I can't match the available options to a piece of art is it OK to use a non-conservation quality mat board (white core class 3) on top with a slightly smaller piece of conservation quality (class 2) board underneath(effectively a double layer of board on top of the art) so the normal board isn't touching the art? It effectively recesses the art slightly but it actually looks quite nice (I think). Just wanted to know from a technical standpoint if it was OK.
