Raw Materials

Ceramic

Hard and wear resistant, it also withstands corrosion and high temperatures

Glass

Clear and highly heat and chemical resistant; often used in sights, lighting, and lab equipment

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing
