Maker skill question

All weapons require plates to make. 50 requires bronze, 60/70 require steel, 80/90 require mithril, 100/110 require adamantium, and 120 require orihalcon.

Damn, just the answer I was looking for
uhm
How many of each :O?
i.e I want to make a lvl 100 knuckle (king cent) do I need to use the same amount of powders to make it (which would be 4) (i.e. 4 adamantium powders and 4 plates to make a king cent)?
