Diamonds...Pressure...and Peanut Butter

Yeah yeah...an unlikely title...what's he going to come up with this time? Yawn yawn.

Okay. Here's the story...here's the problem...and here's the solution. This all has to do, once again--I've skirted this topic before--with the making of man made diamonds. And here's the story. In theory, it should be simple. Diamonds are made from carbon...and so is almost everything else on this earth, including plastics, wood, and even us. Take out the water, squish a human being with enough heat and pressure, and, theoretically at least, you should get a diamond. So, next time any of you start to think your fellow human may be a bit worthless...think again.

Now...here's the problem. Pressure! At the turn of the century, there wasn't a lab around that could achieve a continuous pressure of over three thousand atmospheres. If you want to know what this means... listen. Go down to the deepest depths of our deepest oceans, and you'll only reach pressures totally a tad over one thousand atmospheres. And three thousand atmospheres doesn't begin to cut it for creating a diamond. It turns out that fifty thousand atmospheres or more is what you need to do the trick. Impressed?

In 1905 a man called Percy Bridgeman was able to create a machine that could generate seven thousand atmospheres (50 tons of pressure per square inch). By 1910 he had things going up to twenty thousand atmospheres. He could now get water to become ice at room temperature. Okay...it wasn't a diamond yet...but still...ice without a freezer. Move over G.E.

1930 comes around and Percy's got his equipment cooking in the range of four hundred thousand atmospheres (that's nearly 3000 tons per inch). More than enough pressure...but no dice...um...make that diamonds.

And now...the solution. It will only work if you can sustain a temperature level of 1000 degrees centigrade while keeping up the pressure of over fifty thousand atmospheres. Percy never made it, though he did get a Nobel Prize in physics for his achievements. So...we're off to Sweden. Let me introduce you all to a Mr. Baltzar von Platen. He's considered a genius and an eccentic...all at the same time. But you can't touch him for brilliance in a laboratory. He designs a machine that produces over sixty thousand atmospheres...and sets the pace for those that follow him...re: a scientist by the name of Erik Lundblad. On February 16, 1953, Erik makes history. He subjects graphite to a pressure of 83,000 atmospheres for a full hour...and creates the first synthetic diamond. But it's not announced...and so the race continues...and we end up back in America...with a company called General Electric. The date is now December 8, 1954. Wednesday evening. Herb Strong, a research scientist for G.E., loads his machine with black carbon powder, raises the pressure to fifty thousand atmospheres and the temperature to 1250 degrees centigrade...lets the stuff cook for 16 hours...and makes two small diamonds. December 16, 1954, another scientist does it again. His name is Tracy Hall.

Since then man made diamonds have become almost commonplace accomplishments. Today, production exceeds over one hundred tons per year. But it's all industrial stuff folks...not to worry.

Oh yeah...one more thing. The Peanut Butter. Where does that come in? I'll tell you. As an experiment, a scientist named Robert Wentorf Jr. took a spoonful of the stuff and put it into the machine and presto... the chef's delight...diamond crystals. And why not? Peanut Butter is carbon too you know. As is plastic, and tar, and wood, and us.
