Don't know what size samples you got, but doing 1 tealight is not going to give you any information. You should use at least one pound of wax per 1oz of fo (sometimes you can go up to 1.5ozs) Make a small pillar, or container candle and test for hot throw after it cures. With some waxes, you can get 3 8oz container candles out of...and you'll need to test what size wicks will work for this fo, wax, and additives, if used. Test, test, test.....then let us know how it works for you!!
