In the US, Charles Kaziun started in 1940 to produce buttons, paperweights, inkwells and other bottles, using lamp-work of elegant simplicity. In Scotland, the pioneering work of Paul Ysart from the 1930s onward preceded a new generation of artists such as William Manson, Peter McDougall, Peter Holmes and John Deacons. A further impetus to reviving interest in paperweights was the publication of Evangiline Bergstrom's book, Old Glass Paperweights, the first of a new genre.
