Summary0006027: Melting weapons/armor/etc. yields too much metal
DescriptionCurrently, melting any weapon, trap component, tool, or armor (of any type) returns 3/10 of the item's MATERIAL_SIZE worth of bars. For items whose MATERIAL_SIZE is a multiple of 3, this amounts to a 90% yield, but for other values greater than 3 this goes over 100%:
* Chain leggings cost 1 bar, but melt down to 1.5 bars (150% yield)
* Shields cost 1 bar, but melt down to 1.2 bars (120% yield)
* Battle axes and picks cost 1 bar, but melt down to 1.2 bars (120% yield)
* Spiked balls and serrated discs cost 1 bar, but melt down to 1.2 bars (120% yield)
* Giant axe blades, enormous corkscrews, and menacing spikes cost 1 bar, but melt down to 1.5 bars (150% yield)

For gloves and shoes, this is worse because they are produced in pairs:
* Gauntlets cost 0.5 bars each (1 bar per pair) but melt down to 0.6 bars (1.2 per pair)
* High boots cost 0.5 bars each (1 bar per pair) but melt down to 0.6 bars (1.2 per pair)

This behavior seems to have been introduced in version 0.34.06 - in all prior versions, melt yields did not vary based on MATERIAL_SIZE at all.

See also 0006026 for a different (and much older) problem related to melting other types of items.

Perhaps the correct fix is that metal forges should consume partial bars (i.e., consume one bar more and retain leftover fractions in much the same way a smelter retains fractions when a full bar has not been produced yet).
