A range of decorative domestic metalwares designed by Ronald Hughes and produced in Wales from the late 1960s into the 1970s. Bodies were made from cast Aluminium that was anodised to give it colour. The thin layer of, typically vibrant, colour was then cut-through by machine with a pattern, revealing the shiny aluminium beneath. Patterns included elongated ovals, hatched effects, lines, and diamond shapes. Cylindrical vase forms are the most common shape, but flower pot covers, candle holders, small bowls, and dishes were also produced. The brand name 'Cristillium' was also used.
