Hi. for somone with a good scale, could use this for zinc:
amzn.eu/d/aAFKUIS
I think it will have less residue material in solution and it will last an lifetime..).
That looks like it could be a solution. Agreed, you'll need a scale able to measure in mgs. Amazon seems to have some around $20 in the States.
