TallTayl Posted January 5, 2021 Share Posted January 5, 2021 Hello and welcome. soy and soy blends are famous for sink holes/hidden cavities. Often they can be eliminated or minimized by reducing the temperature you pour the wax. Much depends on the specific brand and type of soy wax you are using.

Eirini katselou Posted January 10, 2021 Author Share Posted January 10, 2021 Thank you.... I add fragrance in wax in 55 celcium and in 50 celsium degrees I pour it. How long I must wait from adding my frangrance until pouring? Quote Link to comment Share on other sites More sharing options...
Pam W Posted January 11, 2021 Share Posted January 11, 2021 Some waxes do create sink holes and require a 2nd pour. You don't need to wait any specific length of time between adding the FO and pouring as long as you've stirred the wax mixture sufficiently. I don't do soy waxes but assume that if you end up with sink holes, that you can level out the top of the candle with a heat gun like I do with my paraffin candles.

How long I must wait from adding my frangrance until pouring? Typically we stir for a minute or two with a tool that really moves the contents of the pot around thoroughly yet gently to not introduce air bubbles. A spatula creates more movement than a chop stick, for instance. From there, each soy wax has its sweet spot for pouting to prevent cavities. Every wax expands when heated, and contracts when cooling. The cavities result from the top of the candle cooling before the middle. The air is drawn down around the wick as it the path of least resistance. Soy wax is quite brittle and you often see mini cracks around the wick when the shrink occurred. Some soy is forgiving about heat gunning, others are terrible about it. Heat gunning some soy (like 444, c1, etc) can cause frosting, additional cracking and weird marbelized swirling as the priming wax from the wick heats and mixes with the soy wax. I dropped 444 like a hot potato when filling cavities took several (up to 5 repours) to fill. The cavities created new cavities, and more wax went in than I though possible. It was like a TARDIS inside the container. Quote Link to comment Share on other sites More sharing options...
Eirini katselou Posted January 13, 2021 Author Share Posted January 13, 2021 Thank yoy for information. I take all in advantage. The basic is that I made some candles but only some of them not all have unsmooth surface near to to wick.And Iam wandering why.I send some photos to have a look. Especially the second one is not smooth..it is like an air inside the candle. Quote Link to comment Share on other sites More sharing options...
TallTayl Posted January 13, 2021 Share Posted January 13, 2021 All of those are cooling issues. Cavities around the wick are where the top cooled and solidified before the middle was cooled. Wax expands when heated and contracts when cool. Even cooling is what you need to prevent holes under the surface. Sometimes no matter what you do a heat gunning or second pour is required. the clothespin surface one is related to heat trapped under the insulating wood. The slower the soy wax cools the larger the grains of soy. to get smooth, shiny soy heat enough to ensure all of the components of the wax blend are nice and fluid. Cool quickly and evenly. Or use additives that do that work for you like paraffin or micro waxes or polymers. Quote Link to comment Share on other sites More sharing options...

Eirini katselou Posted January 16, 2021 Author Share Posted January 16, 2021 Do you have also an opinion about fragrance in soy candles? I put 70 ml of fragrance in 1 kg of wax but the smell is not so strong.Why? Quote Link to comment Share on other sites More sharing options...

This is typical for soy wax as a starting point for typical candle fragrance. An awful lot is dependent on the wax, wick, fo and jar balance with the wick. It all needs to hit a temperature, fuel and air current balance to produce hot throw. I would experiment with wick sizes, wick manufacturers and increased fragrance in different steps to see if you an achieve the hot throw you want.
