A difference is the materials; Kahlo uses oil paint whereas Barton uses synthetic polymer paint‚ gouache‚ watercolour and ink on canvas. The main way that they similar is that both artists perceived duality in their work. Another feature that they have in common is what dualities are present in the work. Kahlo’s artwork reflects the

Chapter 1 Introduction Background of the Study Starch is a linear polymer (polysaccaride) made up of repeating glucose groups linked by glucosidic linkages in the 1-4 carbon positions. The length of the starch chains will vary with plant source but in general the average length is between 500 and 2 000 glucose units. There are two major molecules in starch - amylose and amylopectin. The alpha linkage of amylose starch allows it to be flexible and digestible. Starch-based biodegradable plastics

tends to be inorganic in nature. The white‚ red‚ yellow pigments of paint is inorganic by nature. Organic compounds are based on carbon these are found only on living things. Inorganic is the opposite it doesnt come from living things its from synthetic fibers like polyester or nylon are carbon based but are not found in plants or animals. From a forensics science point of view both inorganic and organic compounds are very important when found in items of evidence. Organic compounds are extracted

My favourite thing about Barton’s work is her use of materials. Synthetic polymer paint‚ gouache‚ watercolour‚ pen. She also often incorporates sequins‚ glitter and beads in her work to give it more life. Her work is very busy and cluttered with imagery.

After his death‚ his body has been exhumed twice (in 1901 and in 2010)‚ in order to examine the circumstances of his death. This was also done to verify what material his artificial nose was made of. The result was that his
