paragraph_text: Aluminosilicate glass
  
  Aluminosilicate glass typically contains 5–10% alumina (Al O). Aluminosilicate glass tends to be more difficult to melt and shape compared to borosilicate compositions but has excellent thermal resistance and durability. Aluminosilicate glass is extensively used for fibreglass, used for making glass-reinforced plastics (boats, fishing rods, etc.), top-of-stove cookware, and halogen bulb glass.
