1: Is the tin/lead weight of the bar measured in mass or volume? The bars I have are 67/33 tin/lead and weigh 1 2/3lbs or approx. 26.66oz. Does that mean that the makeup of the bar is 17.86oz tin and 8.79oz lead or do I have to figure the volume and do the percentages from there.
2. To make a 16:1 lead/tin alloy does that mean 16lbs of lead and 1lb of tin for a total of 17lbs?
