Of course, if you're Shaping Earth into the desired shape and then transforming it you'll be doing ingots of 5 to 20 lbs. This is actually what a spell user would probably be doing. He wouldn't be able to sell a cubic yard of iron.

On why the Earth to Stone Spell exists in the first place it's so gurps Magic would ahve a way to emulate original D&D Wall of Stone and Wall of Iron Spells which did ahver a duration of "until dispelled"..
