@ megandgarr, I can only tell you what I've eyeballed. I'm not trying to sell it, so I'm just playing. I use less salt & more fo than you. I think I've used about 1/8 cup salt - maybe a tad more & about .25 oz (that may be too much even) of fo to that (I just use my eyedroppers for that). I just mix it in a lined dixie cup right before I put it in the melter. I never wrote it down, I just eyeball it. When I have a chance, I may have to dig into our stash of solar salt (no-one tell hubs It's been a great way to use my (cough) stash of oils. To me it's very similar to adding the fo to some carrier oil & putting that in a melter. This is easier to clean up though.
