Bismuth Oxide: Bismuth Burned at a Red-White Heat in a Muffle (Thorpe 1913)
Heated to a red-white heat in a muffle, bismuth burns and its oxide condenses as a yellow powder. Bismuth trioxide, Bi2O3, has sp. gr. 8.21, contains 89.66 % bismuth, and melts at a red heat to a glass without losing weight.

Heat bismuth to a red-white heat in a muffle
Put bismuth metal in the muffle (ours: in a porcelain dish) and raise it to a red-white heat. The metal burns. Ours: a dust respirator for the fume.

Ama-blueprint ahlobene
Lama-blueprint abelana ngolwazi — amasu, izinto noma izimiso
CC0 Isizinda Somphakathi
Le blueprint ikhishwe ngaphansi kwe-CC0. Ukhululekile ukukopisha, ukuguqula, ukusabalalisa, nokusebenzisa ngaphandle kwemvume.
Sekela uMenzi ngokuthenga imikhiqizo nge-Blueprint yabo IKhomishane Yomenzi kumiswe ngabathengisi, noma dala inguqulo entsha yale Blueprint bese uyifaka njengoxhumaniso ku-Blueprint yakho ukuze wabelane ngemali engenayo.
