Silvery white and soft enough to be cut with a knife, gallium has an unusually low melting point at 29.7 C which allows it to liquefy in the palm of the hand.
Harmful effects:
Gallium is considered to be non-toxic.
1kg of Gallium costs $ 220.00
200 g of gallium would make an unusual gift!
Gallium
Metallic chemical element, chemical symbol Ga, atomic number 31.
The liquid metal clings to or wets glass and similar surfaces. Gallium expands on solidification and super cools readily, remaining liquid at temperatures as low as 0 °C .
In various combinations with aluminum, indium, phosphorus, arsenic, and antimony, it forms compounds (e.g., gallium arsenide and indium gallium arsenide phosphide) with valuable semiconductor and optoelectronic properties; some of these compounds form the basis for such electronic devices as light-emitting diodes and semiconductor lasers.
Discovery of Gallium
Before the discovery of gallium its existence and main properties were predicted by Dmitri Mendeleev. He named the hypothetical element eka-aluminum as he predicted the element would sit below aluminum on the periodic table.
Gallium was discovered by Paul E. Lecoq de Boisbaudran through a spectroscope in 1875.
Its now characteristic spectrum (two violet lines) identified it as a new element.
De Boisbaudran extracted gallium in the first instance from a zinc blend ore from the Pyrenees and obtained initially only 0.65 grams from 430 kilograms of ore. He isolated gallium by electrolysis of its hydroxide in potassium hydroxide solution.
The origin of the name comes from the Latin word 'Gallia', meaning France.
I feel well and happy this morning due to, nice e-mail, beautiful day, time for the garden and lots more...I am a lucky gal. I also bought a new guide to insects which are a passion of mine, love those creepy crawlies.
Bought one for my middle daughter J. as well for her birthday. My grand daughter Fabrizia loves it too and immerses herself into the world of entomology. We walk around in the garden to find interesting bugs and try to identify them. It is quite interesting what one can find when one looks!
The book is very thorough in explaining "who is who" in the bug world.
It is called A Field Guide to Insects in Australia; Third Edition.
All confined to barracks was more than I could bear;
I knew you were waiting in the street,
I heard your feet, but could not meet,
My Lillie of the lamplight,
My own Lilli Marlene.
Resting in a billet just behind the line
Even tho' we're parted your lips are close to mine,
You wait where that lantern softly gleams
Your sweet face seems to haunt my dreams,
My Lillie of the lamplight,
My own Lilli Marlene.

"Lili Marlene", is a German love song which became popular during World War II.
Written in 1915 during World War I, the poem was published under the title "Das Lied eines jungen Soldaten auf der Wacht" (German for "The Song of a Young Soldier on Watch") in 1937, and was first recorded by Lale Andersen in 1939 under the title "Das Mädchen unter der Laterne" ("The Girl under the Lantern").
While on leave in Vienna, a lieutenant working at the station was asked to collect some records for broadcast. Amongst the pile of second-hand records from the Reich radio station was the little known two-year-old song "Lili Marlene" sung by Lale Andersen, which up till then had barely sold around 700 copies. For lack of other recordings, Radio Belgrade played the song frequently.
Its popularity quickly grew. Soldiers stationed around the Mediterranean, including both German Afrika Korps and British Eighth Army troops, regularly tuned in to hear it.
Many Allied soldiers made a point of listening to it at the end of the day. For example, in his memoir Eastern Approaches, Fitzroy Maclean describes the song's effect in the spring of 1942 during the Western Desert Campaign: "Husky, sensuous, nostalgic, sugar-sweet, her voice seemed to reach out to you, as she lingered over the catchy tune, the sickly sentimental words. Belgrade...The continent of Europe seemed a long way away. I wondered when I would see it again and what it would be like by the time we got there."
Nor did it end there. The next year, parachuted into the Yugoslav guerrilla war, Maclean wrote: "Sometimes at night, before going to sleep, we would turn on our receiving set and listen to Radio Belgrade. For months now, the flower of the Africa Corps had been languishing behind the barbed wire of Allied prison camps. But still, punctually at ten o'clock, came Lale Andersen singing their special song, with the same unvarying, heart-rending sweetness that we knew so well from the desert. Belgrade was still remote. But, now that we ourselves were in Yugoslavia, it had acquired a new significance for us. It had become our ultimate goal, which Lili Marlene and her nostalgic little tune seemed somehow to symbolize. 'When we get to Belgrade...' we would say.
In the autumn of 1944, the liberation of Belgrade seemed not far away. "Then, at ten o'clock, loud and clear, Radio Belgrade; Lili Marlene, sweet,
insidious, melancholy. 'Not much longer now,' we would say, as we switched it off. It was a stock joke but one that at last began to look like coming true." As the Red Army was advancing on Belgrade, he reflected again on the song. "At Valjevo, as at so many other places, in the desert, in Bosnia, in Italy, Dalmatia, and Serbia, we would tune our wireless sets in the evening to Radio Belgrade, and night after night, always at the same time, would come, throbbing lingeringly over the ether, the cheap, sugary and almost painfully nostalgic melody, the sex-laden, intimate, heart-rending accents of Lili Marlene. 'Not gone yet,' we would say to each other. 'I wonder if we'll find her when we get there.' Then one evening at the accustomed time there was silence. 'Gone away,' we said.".
Based on a German poem of 1915, this song became the favorite of troops of every tongue and nation during the Second World War, both in translation and in the original German. A curious example of song transcending the hatreds of war, American troops particularly liked Lily Marlene as sung by the German-born actress and singer, Marlene Dietrich
