| 41. | In the heat of the furnace the limestone flux decomposes to calcium oxide ( also known as quicklime ):

|
| 46. | Calcium carbonate ( limestone ) is decomposed by heat to produce Calcium oxide ( quicklime ) and carbon dioxide gas.
|
| 47. | In this type of illumination, a gas flame is used to heat a cylinder of quicklime ( calcium oxide ).
|
| 48. | Afterwards, inhabitants cut firewood and timber for charcoal-fueled kilns that produced quicklime from limestone in the Shenandoah Valley.
|
| 49. | A supposedly more stable mixture of calcium hypochlorite and quicklime ( calcium oxide ) is known as " tropical bleach ".
|
| 50. | During this period he discovered tartaric acid and with his friend, Retzius, studied the relation of quicklime to calcium carbonate.
