I would just think that when scaling up to a few hundered grams you would want to weigh it rather than eyeing it out. Too much Hg could be a bad thing, and too little will take foever and a day for the AL to amalgamate.. There should be a 100g rule for this thickness. I say it's 400mg per 100g!
hehe, ok?
