Ed. Kerstin Wickman, "Orrefors - Etthundra år av svensk glaskonst, Stockholm 1998, compare p 34. 'Slottsglaset' was designed by Simon Gate for the 1923 Jubilee exhibition in the city of Gothenburg and they were executed by master glassblower Knut Bergqvist. The idea was that the different versions of 'Slottsglas' would be produced in a limited number of 30 pieces of each model. In fact, significantly fewer were produced.

Simon Gate was a Swedish glass artist, painter, and designer. After studying at the Academy of Arts, he started working at the Orrefors glass factory. Together with the glass artist Edward Hald, he contributed to the glass factory's first international success. From 1916, Simon Gate produced the so-called ’graal’ glass, which master blower Knut Bergqvist further developed from cameo glass. Today, the graal glass pieces from Orrefors are among the most sought-after pieces of art glass among Swedish collectors. Together with Knut Bergqvist, he also created the so-called ’slottsglas’ which have received much attention recently. Simon Gate also became famous for his engraving compositions on the glasses, which were decorated with, among other things, processions and dancing women.
