EXPERIMENTAL LEARNING OF ENAMEL ON GLASS MEDIA ON COPPER METAL AT POLITEKNIK SENI YOGYAKARTA

The learning process is not just a knowledge transfer process but fosters motivation and creativity through more interactive, inspiring, fun, challenging, and explorative learning activities. A learning process that provides unrestricted space for developing creativity and independence by the talents and interests, according to students' physical development and psychological aspects. One way to achieve this can be by conducting joint research in the learning process of enamel glass media on copper metal at Politeknik Seni Yogyakarta. Researchers conduct research with students to expand teaching materials, such as enamel experiments. Enamel is a metal coating technique that uses high temperatures. Enamel material is still complex to obtain, so it is necessary to find a substitute material. One way to be able to find a substitute for enamel media is to conduct experiments. Thus, conducting media experiments in art is very necessary. It is helpful to find a new medium of expression that is more effective and efficient to channel the expression of the soul through art. This research aims to find enamel materials that utilize waste in our environment, namely broken Glass. The experiment will observe: (1). How strong is glass adhesion to copper metal? (2). What is the boiling point of glass waste? (3). How is the color achieved? The results of the experiments show that (1) Waste glass can be utilized as enamel material for copper metal. (2). The average boiling point temperature of waste glass is 900 C. (.3). The desired enamel color game can be done by applying Metal oxide, Cobalt oxide, Copper oxide, Iron, Mangaan, Uranium, and Tin to the Glass
