And you are in Maine, shipping will be easy.
Anyway, let me know.
About the nitric, what's the concentration you can achieve ?
Thanks
I would be glad to but customs won't allow it methinks. Something about crossing the US Border and Homeland Insecurity.
Check around at agricultural supply stores. I bought mine at the local feed and seed store.
I hadn't measured the concentration. I filter and wash the Calcium Sulfate with clean H2O. I just use dilute Nitric. I just want to be sure there is no Chloride content.
I try to avoid using HCl or HNO3 because of the fumes.
