Malachite Bead

Silver Smith of Georg Jensen

The Danish silver company Georg Jensen was founded in 1904 and by the 1920s it had shops all over the world New York, Buenos Aires, Paris, London, Stockholm, and Berlin and by the 1950s Jensen even had a shop on the Queen Mary cruise liner. The son of a blacksmith and born in 1866, Georg Jensen grew up in a poor family in the little industrial town of Raavad north of Copenhagen. He always called it "a paradise on earth", fondly remembering its powerful oaks, towering beeches, and blue clay which he used to sculpture human figures. As a boy, he was sent to work at a foundry to help support his parents and seven siblings. When he was 14, his family moved to Copenhagen where he apprenticed with a goldsmith. In his spare time, he took drawing, geometry, engraving, and modeling courses during which time he decided to become a sculptor.

While it was an improbable ambition for a working class young man, Georg passed the entrance examination of the Royal Danish Academy of Fine Arts and joined its sculpture class in 1887. After graduating in 1892, he first made art pottery while he married and had 2 children. After his wife died suddenly, he decided he would return to his old craft of metalsmithing to support his family making silver jewelry to his own designs. Finally, in 1904, he opened his own shop in Copenhagen and soon had 60 people working for him. His designs were a success, but his business acumen was not as he constantly needed to rely on new investors. Overall, his life was filled with personal sorrow having lost 3 wives as well as eventually the control of the company. In 1925, he left the company and moved to Paris to start a new workshop, but this venture was unsuccessful and he returned to Copenhagen. There, he rejoined the company as the artistic director where he continued to design for the company bearing his name until his death.

The Georg Jensen name has always carried the mantle of the highest quality silver, made using the most expensive techniques of production. Authentic Georg Jensen silver is also quite hard to find, for even in its heyday in the 1930s - 1950s the number of silversmiths employed varied between only about 200 and 250. Today, the firm employs only 12. At one time, Jensen made 33 flatware patterns, 23 of which are no longer produced, and about 1200 holloware items such as bowls, candelabra, pitchers, tea sets, trays, vases, wine coolers, and covered fish platters. Like Georg Jensen jewelry, many holloware pieces were embellished with semiprecious stones like amber, amethyst, garnet, lapis lazuli, malachite, opal, and quartz. Within a given flatware pattern such as the very popular "Acorn", Jensen created as many as 272 separate pieces including serving pieces, fish knives and forks, ice cream spoons, and a fascinating array of other utensils and utility pieces.

While Georg Jensen silver comes in distinct Art Nouveau, Art Deco, and Modern styles, Georg Jensen himself was a follower of the Art Nouveau movemenet. His signature motif, the cluster of grapes, is part of his repertory of forms from nature which included berries, leaves, and fauna which he combined with lightly hammered plain surfaces. Over the years before his death in 1935, Jensen hired a series of talented designers who were allowed to go their own ways. the most noteworthy include Harald Nielsen (1892-1977), the young brother of Jensen's third wife Johanne Nielsen, Count Sigvard Bernadotte (1907-2002), the second son of Gustav VI of Sweden who was known for his classic geometric shapes like cylinders, spheres, and streaming elements, and Henning Koppel (1918-1981), a radical modernist whose unadorned biomorphic designs have become icons of their time and are in great demand. As such, Jensen's greatest talent may have been his ability to find and nurture other talents. One of the most talented, original, and influential silversmiths of the 20th century, Georg Jensen silver designs live on today as one of the most highly sought examples of the art of fine silver.

Georg Jensen has stood for refined and organic design that is both pure and timeless. It is the elegant simplicity in Georg Jensen's products that surprises and delights the senses. Always distinctive and full of life, one never grows tired of using Georg Jensen. Fjorn Scandinavian offers the complete line of the Georg Jensen Living collection. The design appears new and different, but at the same time familiar. Its rounded lines are natural, especially when held in the hand. The Bo Bonfils cutlery is produced in matte finish stainless steel and is an obvious choice for both everyday and special occasions. Please purchase on online www.etabletop.com

I am so confused with calculating theoretical yield So confused!?

Any Help would be great!

use these 6 steps to solve all your stoichiometric type problems

1) write a balanced equation
2) convert everything given to moles
3) determine limiting reagent
4) convert moles limiting reagent to moles other species
5) convert moles back to mass. this is theoretical mass aka theoretical yield
6) % yield = actual recovered mass / theoretical mass x 100%

so the idea is this.. the coefficients of the balanced equation are in MOLE ratios. and you can use those ratios to determine limiting reagent and to convert between the species. ok? watch...

*** 1 ***
2 CuO(s) + C(s) => 2 Cu (s) + CO2 (g).... this wasn't your reaction...

1 Cu2CO3(OH)2 ---> 2 Cu(s) + 2 CO2 + 1 H2O ... is your reaction...

*** 2 ***
1.07g Cu2CO3(OH)2 x (1 mole Cu2CO3(OH)2 / 221.1 g Cu2CO3(OH)2 ) = 0.004839 moles Cu2CO3(OH)2

*** 3 ***
you only have 1 reactant and you're free to calculated mass of Cu, CO2 and H2O.. therefore Cu2CO3(OH)2 is limiting...

*** 4 ***
from the balanced equation.. 1 mole Cu2CO3(OH)2 ---> 2 moles Cu.. therefore...

0.004839 moles Cu2CO3(OH)2 x (2 moles Cu / 1 mole Cu2CO3(OH)2) = 0.009679 moles Cu

*** 5 ***
0.009679 moles Cu x (63.55 g Cu / mole Cu) = 0.615g Cu
that is your theoretical yield. 0.62g Cu.

****************
so you need to memorize those steps and know how to use them...

alternately.. since this is a simple problem with only 1 reactant decomposing into several. and the element you're after is only going into 1 product.. you could do this...
the % Cu in Cu2CO3(OH)2 = (127.1g Cu / 221.1g Cu2CO3(OH)2 ) .. right?

so...
1.07g Cu2CO3(OH)2 x (127.1g Cu / 221.1g Cu2CO3(OH)2 ) = 0.615g Cu

but again.. that only works if you have 1 reactant with the desired element going into 1 product. That wouldn't work very well if you were trying to find the mass of CO2 or water produced
