The Processing Glass wall chart is a detailed and informative educational poster that explains how glass is manufactured, structured, and used in everyday life. Designed for science and technology classrooms, this wall chart provides a clear step by step overview of glass production, from raw materials to finished products.

The chart begins with the preparation of glass, showing how raw materials such as silica sand, limestone, and soda are mixed and heated in a furnace at extremely high temperatures to form molten glass. Waste glass is also added to improve efficiency. Clear diagrams illustrate the mixing process and the formation of molten glass before it is shaped.

Two major manufacturing methods are highlighted. The blowing glass bottles section shows how gobs of molten glass are placed into moulds and shaped with air before passing through an annealing oven to strengthen the final product. The drawing glass sheets section demonstrates how molten glass floats on liquid tin in a float bath, creating smooth sheets that are then cooled and cut.

The poster also explains the structure of glass as an amorphous substance made from silicon and oxygen atoms. A section on types of glass describes how different oxides such as cobalt, copper, iron, lead, and boron change colour and properties. Practical examples include coloured glass, crystal glass, borosilicate glass, and optical fibres.

Finally, the wall chart explores the uses of glass in construction, packaging, laboratory equipment, optical instruments, sunglasses, and telecommunications. This educational poster combines labelled diagrams with clear explanations, making complex manufacturing processes easy to understand and visually engaging for learners.

Our wallcharts are engineered for durability and educational impact, designed to withstand the rigors of both classroom and home environments.
