Hi, I've been using C3 for several years and love it. Let me first say that what works for one won't necessarily work for another. I can offer some suggestions but it all comes down to testing and finding what works best for you. For me, I prefer CDNs and Premier wicks...ECOs work well too tho. I temper C3 but that's for looks and doesn't really play a part in ht. I heat the wax to 185*, add fo (8.5% works well for me and doesn't cause seepage issues), stir 2 minutes, cool to pour temp (125* works for me) and pour. For optimal throw, I let the candles cure for 2 weeks...one week is fine for testing purposes. For citrus fo's, I add at 175* to avoid a fuel smell. CandleScience has some great oils that work well with C3...Macintosh, Mistletoe, Lime Cooler, to name a few. Soy, including C3 tends to be pickier than paraffin when it comes to fo's...wicking, oils, cure time all play a big part in achieving a great ht. Keep good notes, let the candles cure, test a few different wicks, dont go overboard on fo (will lead to other issues like seepage and clogging the wick)...you'll get there! Have fun! HTH
