Why continue to buy platinum coins

I own some osmium and iridium and the 1/10 oz pellets are the same size. my platinum pellets are just a bit larger. I've been trying to make an osmium coin for a long time. the closest i got was mixing osmium powder with PMC, shaping it into a coin form, and setting it in a digital kiln. it would have been 80 percent silver, 20 percent osmium. It crumbled.

I'm going to have to get some Os fishing weights this year.

Not temp. They can control that well and the melting point is 2410. FWIW, the "Handbook of Chemistry and Physics" lists iridium as 22.42.

 

I could be wrong by I think my calcuation was about right

100 cm in a meter
cubed is
1,000,000 cc in a Cubic Meter

a cubic inch would be 2.2cm x 2.2 cm x 2.2 cm or 10.648 cubic centimeters

2,000kg/3,000,000 cc = x/10.648

solve for x and divide by 1000 for gram weight or roughly 6.6grams per cubic inch?

Os is more dense but my numbers are in gm/cc

Needless to say, they are very close to the part per thousand although if there are many metric tons of it in the planet core this would be significant.

Cool....

Um - what bout the very toxic Os oxides?

Ruben

 

Ruben, an inch = 2.54 cm. That will give you 16.387 cc/cu. in.

 

yes

I was thinking lbs to Kgs which is the more common conversion I make. 2.54 cm per inch is correct.

I took a lot of precautions.
I live in a rural area and have a barn that is a mile away from the closest home; It is still hooked up to electricity from when my grandfather used grain-elevators in there. I use to make oil paint for a living, so i have some pretty high quality masks left over from that. The kiln is digital so i can program it, and i don't have to be close by during the firing process and i can program it to change temperatures. I let it set for 48 hours before i went back with my mask on. -- Osmium in solid form is not harmful.

 

joe dont ruin yourself by buying coins there are other ways to do that that re more fun

 

Not according to the Hasmat sheet I have in the lab. Over time it leeches a tetraoxide gas that is very toxic.

Ruben

 

By the way, I am very impressed.

Spock... Too late.... and I have you to partly thank for that! I never bought foreign coins until I met you. Its been all down hill since.

 

not foreign coins be careful of us mint coins you kno9w how much moiney we have lost in the buffalo and the fs series just this year let me tell you we could have bought 20 ounces of silver at least just on those coins with the money lost

 

I love losing money. If I don't lose money, Im not happy. I love seeing the stock of my company drop 26 points in 2 months. I love seeing half of my savings disappear in the past few months. I love buying coins that have no value to them and continue to decrease in value every day. I love US coins. This is my cross and I must bare it. What's there to be careful of? :headbang::goofer::vanish:

 

20 ounces of Silver? Your complaining about $300 bucks?

Ruben

 

i need to get some platinum coins

 

FWIW, wikipedia says it is neutralized by vegetable oil.

 

Very Sanitary ....
never mind. .... thats the other thread....
