POPSColor in Nature: Wood About petrified wood (from the page): "Petrified wood is a type of fossil: it consists of fossil wood where all the organic materials have been replaced with minerals (most often a silicate, such as quartz), while retaining the original structure of the wood. The petrifaction process occurs underground, when wood becomes buried under sediment and is initially preserved due to a lack of oxygen. Mineral-rich water flowing through the sediment deposits minerals in the plant’s cells and as the plant’s lignin and cellulose decay away, a stone mould forms in its place."

POPSColor Inspiration: Pattern and Decoration of Beatriz Milhazes
"Many of these explosions of colour originate in her small, compact studio, where she has been based since 1987. It is situated right next door to Rio’s luscious botanical gardens, and, inevitably, the forms and patterns of the flowers – delicate swirls and leaf-like shapes – have found their way into her paintings. She has also “taken advantage of the atmosphere of the city”, with its rich urban mix incorporating chitão (the cheap, colourful Brazilian fabric), jewellery, embroidery and folk art. Other influences range from architectural – the work of Roberto Burle Marx, the landscape architect and garden designer who created the five-kilometre Copacabana beach promenade in Rio – to Pop symbols such as Emilio Pucci fabric patterns. Painterly inspiration comes from the seventeenth-century Dutch artist Albert Eckhout, who travelled through colonial Brazil, and the Brazilian Modernist Tarsila do Amaral, as well as Mondrian, Matisse and Bridget Riley."
