Physical and pecuniary properties of metals

Gold (Ln. Aurum) is a yellow pecious metal. It has the highest monitary value of any available metal in the game world and high symbolic value as well. It is also very heavy, with a density of 11.18 oz. per inch cubed. In game terms 1 oz of gold is worth $1250, so a cubic inch of gold is worth $13,969. Gold bricks used as props in movies are about 6"x3"x2" would weigh about 25 lbs and cost $502,885. Pure gold never tarnishes and is extreamly ductile. Of course gold doesn't have to be pure. For impure gold calculate the carat of the gold by the following formula CARAT=24(Mg/Mm) where Mg is the mass of the gold and Mm is the mass of the metal (gold + impurities). Roman coins are 24 carat (pure gold), 18 carat gold is 75% pure and 12 carat gold is 50% pure. Assume the impurity is copper for denisty calculations unless otherwise stated.

Electrum is a naturally occuring alloy of gold and silver. For game purposes it is a 50/50 mix of gold and silver with a denisty of 8.621 oz per cubic inch and worth $650 an oz.

Silver (Ln argentum) is a white precious metal. It is less dense, less valuble and less symbolic than gold. It has a denisty of 6.068 oz per cubic inch and is worth $50 an oz. So a "brick" of silver would weigh 13.7 lbs and cost $683. It tarnishes black.

Copper (Ln cuprum) is a reddish, yellow ductile metal. It has a density of 5.165 oz per cubic inch and is worth $5.5 per oz. So a "brick" would weigh 11.6 lbs and cost $64. It tarnishes green.

Bronze (Ln pyropus) is a copper/tin alloy. It has a denisty of 4.627 oz. per cubic inch and is worth the $5 per oz. A brick wieghs 10.4 lbs and cost $52.

Tin (Ln stannum) Density 4.211 oz per cubic inch and is worth $0.40 an oz. A brick is weighs 10 lbs and costs $3.80.

Iron (Ln ferrum) Density 4.54 oz per cubic inch. Value: $0.50 oz. Brick 10.2lbs $5.11.

Lead (Ln plumbum) Density 6.56 oz per cubic inch. Value: $0.10 oz. Brick: 14.8 lbs $1.48.

Steel (Ln chalybs) Density 4.54 oz per cubic inch . Value:$1 oz. Brick: 10.2 lbs $10.20
