What is this in my alcohol extract?

[GrowGoddess]

When I make RSO, I do so using 99% Iso alcohol.

When I do th4e first rough filtering of the oil/alcohol mixture, I'm left with a sandy appearing stuff at the bottom of the unfiltered alcohol.

What is this sandlike substance? and should I be doing something with it?

Thanks

The sand like substance is the stuff you do not want in your oil. What exactly it is specifically, I am not sure. It is good that you let it sit and allowed gravity do some of the filtering for you.

Filter it back and fourth a couple of times from bowl to bowl allowing the sand like substance to sink to the bottom before running through the filter so it does not clog the filter up too badly.

What should you be doing with it? As far as I know, dispose of it. It is the trash of the plant as far as I am concerned. It is the stuff you want to filter out before making the oil, it is not THC.

My opinion anyway.
