Design Technology - Topic 4.2c

Solid made by rapidly cooling a mixture of silica, soda, and lime. Transparent, inert, and sustainable with increased thermal insulation, compressive strength, and hardness. Decreased tensile/impact strengthBo

Can be modified by adding metallic oxides that vary in amount and type

Commercial glass that is the most commonly used. Medium-low thermal shock

Soda glass that has been altered using oxides to increase thermal conductivity

Glass that has been heated to its melting point and then blasted with cold air. Increased brittleness

Layers of glass with plastic sheets between them. When impacted, the glass fragments are held in place, preventing cracks from growing

Very long strands of glass that can be woven into mats or used to reinforce plastics

Recycled glass that is added to new raw materials to make new glass
