Red phosphorus may be formed by heating white phosphorus to 250 °C (482 °F) or by exposing white phosphorus to sunlight. Red phosphorus exists as an amorphous network. Upon further heating, the amorphous red phosphorus crystallizes. Red phosphorus does not ignite in air at temperatures below 240 °C, whereas white phosphorus ignites at about 30 °C.

Famous quotes containing the word red:
“look the spangles
that sleep all the year in a dark box
dreaming of being taken out and allowed to shine,
the balls the chains red and gold the fluffy threads,
put up your little arms
and i’ll give them all to you to hold”
—E.E. (Edward Estlin)
