Chinese New Year. In the decorative arts, a bird is rarely just a bird and a flower seldom represents a simple flower. These evocative symbols conjure different narratives, ideas, and emotions according to the context in which they are portrayed and the viewer who observes them. That is what makes them so powerful.
Glass is formed by heating sand to its melting point. Objects are  then either cast or blown to their desired shape and allowed to  cool slowly    Glass is made from â¦ a mixture of sand and other materials. Just  regular sand can be made into glass, but it must be heated to about  3,000 degrees Fahrenheit.
A core is made of clay mixed with sand, to which have been added organic materials such as straw, grass, leaves or seeds. This core is mounted on a metal rod, and the glassmaker wraps it in hot semi-molten glass drawn into a thread. The glassware thus produced is decorated by the addition of glass threads of different colors, which are formed into zigzags, as here, or into garlands. Once the glass is cool, the clay core is discarded.
