* The copper and iron can be combined into single large lumps as only the amount required is used.
*It is easy to gain skill by making bronze or brass first, this uses less important items ([[tin lump|Tin]], [[zinc lump|Zinc]] and [[copper lump|Copper]]) rather than using [[charcoal]] which can be quite difficult to get hold of and is annoying to lose.
*Metallurgy is only really useful for increasing steel creation success rates at the moment, as both [[brass lump|Brass]] and [[bronze lump|Bronze]] have very little to no additional utility compared to the metals they derive from.
