How much silverite will he require? That is a good question. Looking back down at the sketch, Sam clicks his tongue a couple times. "I'll have to draw up a few sketches and figure out the dimensions first. Once I've gotten something you approve of I can calculate how much silverite you'll need." If it was a common metal he'd just have them collect a whole lot and be done with it. Silverite would be harder to find, so he wanted to have a good estimate to give them - not too little or they'd have to go back out, and not too much which would take more time.
