  Bunsen burner - Hutchinson encyclopedia article about Bunsen burner
The Bunsen burner, used for heating laboratory equipment and chemicals.
Air is drawn in through airholes near the base of the tube and the mixture is ignited and burns at the tube's upper opening.
A large curved retort was boiling furiously in the bluish flame of a Bunsen burner, and the distilled drops were condensing into a two-litre measure.

After leaving the crater, it underwent enormous expansion, and Anderson and Flett were led to suggest that possibly at the moment of emission it might have been partly in the form of liquid drops, which on solidifying evolved large volumes of gas held previously in occlusion.
Hence the height of a volcanic mountain in activity, measured to the rim of the crater or the terminal peak, is not constant.
The crater of Tongariro is in the solfatara stage, whilst Mount Ruapehu is regarded as extinct.

 Bunsen, Robert Wilhelm - Hutchinson encyclopedia article about Bunsen, Robert Wilhelm
Bunsen was working on cacodyl compounds, unpleasant and dangerous organic compounds of arsenic, until a laboratory explosion cost him the sight of one eye and he nearly died of arsenic poisoning.
Using electrolysis, he was the first to isolate metallic magnesium and demonstrate the intense light it produces when burned in air.
The Bunsen burner was probably used to heat metal salts for spectroscopic analysis, a technique which he pioneered, together with physicist Gustav Kirchhoff, and by which he discovered the new elements.

 Lighting - LoveToKnow 1911
They took the short Bunsen burner, as found in the most commonly used upright incandescent burners, and fitted to it a long tube, preferably of non-conducting material, which they called an isolator, and which is designed to keep the flame at a distance from the Bunsen.
The chief portion of the emitted light proceeds from the incandescent crater; hence the form of the illuminatingpower curve, as shown by A. Trotter in 1892, is due to the apparent area of the crater surface which is visible to an eye regarding the arc in that direction.
Wilson in 1895 attempted to measure the brightness of the crater under various pressures, and found that under five atmospheres the resistance of the arc appeared to increase and the temperature of the crater to fall, until at a pressure of 20 atmospheres the brightness of the crater had fallen to a dull red.

 Lavoisier (crater) - Slider
Lavoisier is a lunar crater that is located near the northwestern limb of the Moon, at the western edge of the Oceanus Procellarum lunar mare.
It is located to the southwest of the Von Braun crater and southeast of Bunsen crater.
The interior floor of this crater is notable for the curving ridge that parallels the northwestern inner wall.

IAU spelling changes pre 1982 8 craters whose spelling was changed prior to AW82 by the IAU but for which the changes were rejected by AW82 on the grounds that the older versions were more familiar and established in the literature.
Note that the crater Greaves appears in AW82 under its correct name and also under its old name of Lick D. For non-craters, I have adopted the traditional nomenclature of AW82 in which the "Mons" is omitted for mountains Pico, Piton, R:umker, Gruithuisen Gamma/Delta, Hadley Delta, rather than the IAU version with Mons added.
Specifically, the fact that Schmidt 1878 used Bunsen for one crater would (if I knew which crater) give it an 1878 entry in that feature's discoverer column, but would not affect the nomenclature approval column for either that crater or the current Bunsen crater, approved by IAU 1964.

 Bunsen (crater) - Education - Information - Educational Resources - Encyclopedia - Music
Bunsen is a lunar crater that lies near the northwestern limb of the Moon.
To the southeast is Lavoisier crater, and to the northeast lies Gerard crater.
Within the crater, the floor is pitted by tiny impacts, and has a rille system of criss-corssing clefts near the northern and southern rims.

 Volcanic Images - The Men of Kawah Ijen
A gleaming torrent of yellow-white steam tumbled up the crater wall and loomed towards me. My first instinct was to avoid the cloud altogether, but I was not about to turn tail and run, not yet.
Sometimes the crater has been so full of fumes that even passing birds have been gassed in mid-air; shining wings honed to perfection and reduced in seconds to a tumbling ball of dissolving, limp feathers.
The climb out of the crater had been excruciating, with scarcely any reprieve from the fumes or my head, that had felt on the point of erupting itself.

The locality is Meteor Crater, or Coon Butte, a crater-like depression about three-fourths of a mile in diameter and nearly 600 feet in depth, in Coconino County, Arizona, near the main line of the Santa Fe railway.
A possible explanation of the formation of Meteor Crater is that it was due to the impact of an immense meteorite.
If this be true, we have at Meteor Crater, Arizona, a unique spot on the earth's surface, but one that perhaps could be duplicated if we had a complete geological history of the earth.

 ETNA ERUPTION UPDATE, 20-28 June 1999
As effusive activity from the fissure near the southeastern base of the SE Cone is gradually decreasing, renewed activity may be expected from the craters soon after the cessation of the lava outflow.
One fissure-like vent had bunsen burner-like emissions of burning gas, an activity which had occurred frequently at the SE cone during 1997 and 1998 during the long-lived mild Strombolian activity.
The magma then remains in the central craters where it is degassing, or drains through fissures like the one in activity since 4 February.

 The Katmai National Park
Robert F. Griggs, who headed the expeditions which explored it, states that the area of the crater is 8.4 square miles, measured along the highest point of the rim.
Bunsen's geyser theory, now generally accepted, presupposes a column of water filling the geyser vent above a deep rocky superheated chamber, in which entering water is being rapidly turned into steam.
When this steam becomes plentiful enough and sufficiently compressed to overcome the weight of the water in the vent, it suddenly expands and hurls the water out.

 Philologos | Mazzaroth by Frances Rolleston
A plumed female figure, holding a vase or cup in each hand, while responding to the constellation Crater, may be a memorial that at the arrangement of the emblems, the invention of astronomy, the summer solstice was there, and consequently the pouring forth of the inundation of the Nile.
***Bau, according to Bunsen, is the verb "to come," and the noun derived from it, in the hieroglyphic, as in the Hebrew and Greek, and their derivative languages.
Bunsen gives a very similar word, Maha, as an archer; also Ar, as a gazelle or antelope, which perhaps, suggested by the name Yareah, gave rise to the usual Greek attribute of the huntress Diana, and perhaps to her being called a huntress, which does not seem a suitable personification of the moon.

There was a small crater in the middle of the laboratory bench.
It was a good job, the technician thought, that the bench was an old one made of solid wood, rather than one of the newer, flimsier metal ones built from a kit.
The wooden crater was scorched and a whisp of smoke curled up from it.

Spectroscopy was discovered in 1859 by Gustav Robert Kirchhoff and Robert Wilhelm Bunsen (of Bunsen burner fame).
They made a prism-based device that separated the visible light emitted when substances were vaporized in the flame of Bunsen's specially-designed burner (it had a high-temperature, non-luminous flame).
A lunar crater, a Martian crater, and an asteroid (#2635 Huggins) have been named for William Huggins.

To make such a device, all that a simple-minded anarchist would have to do would be to take his container of bottled gas and place it above a can of Sterno or other gelatinized fuel, and light the fuel and run.
Then, by attaching a "crater maker", or CO2 cartridge bomb to the rocket, a bomb would be added.
