So, im trying to make concentrated sulfuric acid according to the video above. I dont know shit about alchemy whatsoever, so my 2 questions are:

How long should i burn the powder sulfur while mixing the produced sulfur dioxide with hydrogen peroxide?

How long should i heat the sulfuric acid to concentrate it to the maximum amount? (at least 90%)
