IGI 4630 Harmony Blend Paraffin Wax Slab
Choose a Variant

IGI 4630 Harmony Blend Wax is a single-pour, fully refined paraffin wax for containers and tealights. This wax adheres well to containers, and creates a smooth, opaque, and slightly glossy finished candle. No additional additives are needed—just add fragrance and color. 

Packaged in slab form, IGI 4630 is soft and easy to cut for use. The weight on slabbed wax can vary slightly. Cases contain four slabs of wax packaged together in a reinforced cardboard box.

Candle Maker's Notes: Glass adhesion is sometimes tricky. We recommend experimenting with different pour temperatures (+/-5°F, or 2.8°C) and preheating jars prior to pouring the wax. 

Tunneling can also occur on the first few burns, so we recommend trying at least 3-4 burn cycles before making any conclusions. Paraffin waxes tend to burn down in early burns before spreading out to a full melt pool. If you're still seeing burn issues, try a different wick size. 

Paraffin waxes tend to have darker soot over soy when burning. If you're experiencing excessive soot, we recommend testing different wick sizes, or double wicking in larger containers (3.3"/8.4 cm diameter or larger).

Helpful Tips

  • Cure for 3-5 days before burning for maximum hot throw.
  • Use our Wick Guide to help get your testing started.

This 4630 has great HT. I thought my candle was tunneling until I tested all the way down. After the 2-3rd burn the wax would usually catch up and burns evenly. Burn the candle all the way before deciding! I heat to 190 add FO stir for 2 minutes and then pour around 170 or when my 2 minutes is up. I am using LX14-18 depending on my FO and use a 8-9% FL.

CT and HT is great, but…

The adhesion is awful, even when heating the vessels up before pouring. I tried different pour temps and still get the same poor adhesion results!

Great wax but…

My first time using the wax, my cold and hot throw is great! But, when I burn the candle the room gets dark. I believe it’s called sooting. How do I get rid of it? Help!

Great throw, lots of soot, poor adhesion

This wax has some of the best throw out there. I have just 2 problems... Lots of soot, and the adhesion is AWFUL. If you use a full label over the glass it looks okay, otherwise, your candles are going to look like garbage. I've tried everything; heat the jars, pour the wax at the same temp as the jar, let the wax cool significantly and pour while cloudy, etc. Nothing works. You WILL have poor adhesion with this wax. For me, I'm willing to compromise for excellent throw. I make a stunning label so people don't seem to be bothered by the adhesion issue.

Great HT. I thought mine were all tunneling too and never would finish that wick testing, before trying a bigger wick. But this whole time I think it would have been fine. After the 2-3rd burn it usually all comes together and burns evenly. I think i was comparing way too much on soy wax and how it tunnels and can ruin the candle. Burn the candle all the way before deciding!
