Glass is manufactured from sand, soda, and lime by using high heat. Instead of forming crystals when it cools, glass is a super-cooled liquid that can be manipulated into any shape while hot. Easy to make, glass is recyclable and resistant to change. Natural glass forms when lightening strikes sand with the right combination of minerals.
Glass blowers create special glass objects with their artistic skill called "whimsies," which often include swans and vases.
Acrylic scratches easier than glass; however, acrylic is seventeen times stronger, softer, and more flexible which makes it highly impact resistant. Acrylic is more portable because it weighs half the weight of glass and insulates better than glass which reduces fluctuations in temperature. The high transparency rate of acrylic is better than glass which acquires a green tint with increased thickness. When safety and weight are an issue, applying a pane or sheet of plastic composite is often used instead. This is called ACRYLIC GLAZING. Contrary to popular belief, acrylic does not turn brittle or yellow over time like regular plastic does. Unfortunately, acrylic costs more than glass and is highly flammable.
Acrylic is used for many things like aquariums, display cases for collectibles, bullet-proof windows, etc.
