    Title: Amorphous Silica + Heat Forms Crystals
    Type: Text and Picture Slide
    Content: Includes photo of stacked bags of amorphous silica.

    Speaker Notes: Another type of silica which has the same chemical formula as crystalline silica is called amorphous silica. Amorphous silica is not crystalline in nature and does not cause silicosis, although it may be associated with other kinds of lung problems. However, where sufficient heat and/or pressure is applied to amorphous silica, as in calcining or mining, crystals may be formed. This is one way in which workers may unknowingly be exposed to crystalline silica.
