How did you/they determine the amount of lead?

In first year chemistry we learned qualitative but not quantitative
analysis.
Some of the most useful chemicals for analysis are now restricted as
hazardous.

Put it on a weighing scale.
57grammes
From 100g of the gelana concentrate.

It looked like lead and had a lot of density.
No assay of the metal yet.
