Adamantine's Weight

[GnomeWorks]

I need to know how much adamantine weighs... and how much a 4' by 7' by 3" door made out of adamantine weighs.

This is really old, but you might find it useful...

From The Dragon #17, August 1978
Mithriferral Carbide sold under the trade name of Adamanite is an expensive alloy of Mithril, Carbon, Iron, and certain other materials known only to a very few metal workers, armorers, and alchemists. It is approximately 4/5 the weight per density of iron and of a much higher tensile strength....

Wow, that is old...

Thanks for the info!

First, I assume that adamantine doesn't affect weight in 3.5, since there is nothing stating this (as opposed by mithril weighing 1/2 as much). So, using Iron, instead of steel, to representent adamantine, I get the following numbers.

From www.webelements.com :
Density of iron = 7874 kg / m^3
www.onlineconversion.com says this is 492 lb/cubic foot.
Now, we have a door 4 x 7 x .25 feet, or 7 cubic feet. Thus, the door weighs 3,444 lbs, about 1.75 tons.

Don't know how much adamantine costs per pound, though.

From the same article.

From The Dragon #17, August 1978
Hardened plate adamanite sells on the open market for 20-40 (depending on availability determined by DM) times its weight in gold. Temperable Adamanite capable of holding an edge sells for 25-60 times its weight in gold depending upon the above consideration.

That's going to be one very expensive door!

Or try this thread:

On the Value of Adamantine

Of interest:

Adamantine (the alloy) weighs about 375 pounds per cubic foot.

4' x 7' x 3" door (fortuitously, 3" is 1/4 of a foot so we have 4x7x1/4 or just 7) is seven cubic feet.

Seven times 375 is 2625 lbs.

So right around a ton and a quarter.

And at 5,000 gp per pound, this door is worth a cool 13,125,000 gp. (13+ million)

Thanks!

Here is one last tidbit, on the appearance of this material:

From The Dragon #17, August 1978
Adamanite plate or chain are usually a dark color (55% black 25% dark blue 20% dark green) with a radiant glowing glaze. Adamanite that is tempered to hold an edge is most often silver in color as bright or brighter than the mithril used to produce it.
