The product of an unlikely collaboration between the Spaniard Salvador Ysart and Isobel Moncrieff at an industrial glassworks in Perth, this distinctive glass was manufactured by family members in two distinct phases from about 1922 until c.1961: first under the name Monart at Moncrieff's and from 1946 at the Shore Works as Ysart Brothers Glass. Unlike post-War Ysart that typically carries an acid-etched signature, very few pieces of Monart glass were ever signed. The major difference between the pre-War Monart glass and that of the post-War Yasart era is in the range of production colours and a wider range of shapes. Typically, Yasart reflected the more muted tastes of the 1940s and 50s with softer pastel shades.
