robby go back to the first two pages and there is lots of discussion on both things that you mentioned.....different oils and hardening the stuff on a plate (which I've tried and DOES work....with cocunut oil). I'm pretty sure you will get the information you need there.

Vilo....once the capslules harden I haven't had any problem with them leaking etc....I put them in regular pill bottles and they stay solid unless you put them next to something hot (at least they have for me.)

Have fun!!
