Is there any nutritional value in either?
weigh the aluminum foil first (in units mg maybe or grams) then divide the weight by area of the foil (100cm^2 for your case)after doing this divide the nothus obtained by the density of aluminum (in 1/cm^3)You'll get the thickness in cmDimension checkstep one mg/cm^2 step two mg/cm^21/cm^3cm
Gold and silver leaf are made of just that, gold and silverFood Grade leaf is supposed to be gold and silver that isn't alloyed with other toxic metal such as tin or leadTo make it the put as little as 1/20th or 1/30th of an ounce between sheets of paper and stack them up to about 50 - 60 highBind them together and beat the stacks with a heavy mallet for hours until they are that thinI am sure this method has been update somehow to something like how they make aluminum foil only rolled out much thinner.
