first make sure you have the right size wick to start with. add the fo around 170-180*. you aren't going to weaken the strength of the fo. that only happens if you mix it, then keep it at a high temp for a long period of time, or reheat it too many times. we did a side by side comparison with adding fo at the manufacturer's recommended temp. which i think was 120* and adding at 170-175*. we found the latter had a stronger hot throw. concluding that adding the fo at the lower temp doesn't allow the fo to fully mix and bind with the wax; thus the lighter hot throw results. 1 oz per pound will definitely be enough for fo's that have been added over the last 3 or so years, but a few prior to BC using soy, aren't great throwers. a lot are tho. every nose is different and you might find you prefer to use 1.5 oz per pound. it's preference. next, to get smooth as possible tops, let cool to right about 100*, then pour. ez-soy shows it's best potential if you let it cure a couple of weeks, but there several that threw really well after a few days to a week. make sure you let your testers cure well and that you are testing the candle in an appropriate sized room. and burning the right amount of time. oh and it can be very easy to get candlemaker's nose if you have been pouring quite a bit. hth!
