SN question - Technical grade OK?

[sanz1014]

Can someone help me…Will Technical Grade SN work to ctb? I know Stan's Guide says food or laboratory grade, but what about technical grade?

Not sure how true this is bc it's only from what I've read from responses by others on here but I read yes as long as it is over 95% pure. I was just researching the same thing myself

If technical grade is around 85-90%, then it is inadvisable as per the guide.
