A 6% load is enough for a very good cold and hot throw in 4794. You won't have to worry about seepage if you go over that amount, IGI changed the formula at least according to the PIS on their website http://www.igiwax.com/resource/Pillar_Candle_Waxes I use 4974 for votives and the last batch I got I had to make some adjustments to be able to use 6%. At 6% it just won't burn properly and the honeycomb effect when it sets up in the pour pot is so bad I could house bees in it, I was able to make it work though. I get my wax from Candlescience too and I know the PIS on their site says 3%-6%, but they may be unaware of the change or they just haven't had time to update their site. I did send an email to IGI on Saturday to make sure the formula has been changed and the FO load in the PIS isn't a typo, just waiting to hear back from them. If you have any problems with it feel free to pm me.
