But of course no one would ever ask what kind of unit YOU use, right? To achieve the TRUE' golden silver? Gosh, I can postulate an implied outcome---sooo very odd.
If I kept my maker at the right temperature, it always came out clear, and I got some in the neighborhood of 60 to 70, many times and if it got too hot, amber at 15 ppm, so that sounds hinky to me.. So, although you seem quite the nice and reasonable fellow(?) yeah, I guess I have some questions about your information and motivations.
