Friedrich Böttger ...1682-1719,

he used concave mirrors to lead the sunlight on his works.This way he receive
a strong heat.

Still am not sure! Can I put direct sunlight on all, or should I try it
only with solar plants?

I usually use the sun to extract the sulphur from my plant works. (using rain/snow as my mercury)
Other times i use a candle flame. (but usually thats cause its rainy and thus i cant use the sun)

Ive never had any bad from it, but i think its a good question. :)

Thats what I thought about also. All healing tinctures have to be kept in the dark,
so I cover them now with a piece of cloth.

Yes I think it is a very good idea. :)

It would be interesting to use the sun in all stages and really load it with solar energy.
I mean besides the sulphur extraction, you could use a magnifying lens for
the calcination. I've calcined antimony with a lens before. It's fun. Although time-consuming.

The UV rays of the sun are well documented to decompose essential oils.
