Melting point


Recommended Posts

Hi all.

I've been lurking for a while and have pick up tons of useful information. Alan sorry to see the problems you have been having. Hope you managed to get all the stuff back. its a great message board.

I have been making candles on and off for a number of years now. Lately i have started to get more pro about it and in time hopefully even sell my candles.(so far they have been given away as presents) Anyway i have been reading with envy all the different types of waxes people are using here :D . In Ireland i'm finding it hard to find a place that sells different types of waxes. Parrafin wax i can get no problem.

So what i was wondering is it possible to mix up your own wax using parrafin wax and different additives.

If so any suggestions as to how?

Also is there a way of working out the melting point of a wax when you don't have any written details on it.

Hope this doesn't sound to crazy :eek:

Thanks SatinDucky..

Yep they are, they have been puzzling me for a while. but they do make for a grand entrance from lurker to poster :cool: Hopefully someone might have an idea

I use straight paraffin all the time. I prefer it to a preblend. My additives of choice are vybar (will make opaque and aid in scent retention and stearic (a/k/a stearine) which will also aid in scent retention without imparting opaqueness. Typical use of vybar is 1/2-1 tsp. per lb. and stearic, 1-3 tbs per lb.

Those aren't hard questions at all.. I follow basically the same receipe as Eugenia, I tweek it a bit until I am happy with it :) usually it is 1 tsp Vybar and 2 Tbs. stearic acid per lb

LOL, I would have thought you could give her an answer instead of just racking up posts.

That was my way of bumping her post back up since it was almost at the bottom of page with no answers, not trying to rack up posts :(

Apparently I read it wrong.. I thought she was asking how to make paraffin for some odd reason :o

And her other question still isn't answered.... to me it's a hard question. And since that was the thread name, that was the question I focused on.

I had seen a guide somewhere for determining the meltpoint, but can't recall where it was off hand.

AS for mixing your own blend, it is very possible. The improtant thing is to test and test and test some more. I'm still working out the ups and downs of additives.

If you are wanting to do a mottled candle, use a bit of stearic and FO, but no vybar.

This is what a chemist at Astorlite told me about determining the meltpoint - I have never tried but he said that you melt the wax just to the point where it is completely melted. Dip in the thermometer so that the bulb only is immersed for a second - pull out the thermometer and turn it slowly around and around - the temp registered should give you a fairly good idea on the meltpoint. Again - I have not tried this but maybe it is a starting point.

HTh,

Belfrie, if its the same thing I saw, basically you want to melt a small bit of it, then take your thermometer and stick it in. At the point it starts setting up - note the temp - that is roughly the meltpoint. Its actually the "congealing point". The meltpoint is actually around 1 to 2 degrees higher (in paraffin).

CMG - England is close so if you want to you can order supplies from there. I think its ok to post these here because I don't think people in the US will be paying the shipping :)

wow. thanks everyone at least now i know i'm not crazy for thinking about blending. Some intersting ideas there about working out metling points i must try. I do use stearic and straight parrafin wax and really like how the candles look compared to pre mixed stearic and parrafin you can get here. My main idea at the moment is seeing if i can create different blends with different melting points that can be used together like in an embed candle where the centre melts and not the outside, like hurricane candles. Hence the questions.

Eugenia and candlemomma what types of candles do you make with your blends, at the moment i'm mainly doing pillars and novelty ones.

Henryk thanks for the websites. they look good and useful. The only problem with the UK is the exchange rate. What i save on shipping i lose on the exchange rate.

Thanks SatinDucky for looking out for me. also i'm an Irish Man. ;)

I make votives and pillars with my straight paraffin. You really do need a higher MP wax for hurricanes. What is the highest you can find? Typically they are above 160 degrees, but still straight paraffin.

I don't do hurricanes but I have made embedded pillars. I make a core candle, leave the wick long. When you wick the core candle, underwick it a bit, a might smaller than what you think it should be so it burns slower. Thread the wick of the core candle through the wick hole of a larger mold. Pour the higher MP wax around the core candle.

Hi E.

Haven’t got into the votives yet, I have made a few embedded pillars alright. First few times I used a metal insert but that didn’t work out to good :( . I use the same method as yourself except I use a wick pin which I find great to centre the core candle. The higher MP wax I was using was a hurricane wax I had got from the states as part of a kit. That’s when I found out how much shipping wax to Ireland costs. It is really nice wax but just too expensive in the long run.

So that’s what started me thinking of how would one go about raising the MP of straight paraffin wax and how you would work out the MP as you went along. (I think I may have being an alchemist in a previous life. :cool: ) So you wouldn’t have to go and buy special waxes, for some strange reason I like the idea of creating my own blends. Also I’m curious about the effect heating wax to different temps has on the wax. You know when you see a project in a book its says to heat to a certain temp?

Pandon me, kind SIR :D

of course dear Lady ;)

I am going to try and remember how to determine a melting point but it has been a long time since I was in chemistry. If I remember my chemistry lab correctly, we took a range for when the substance melted. We noted when we first saw the substance turn to a liquid and then when all of the subtance was melted. Ideally, it should only be a few degrees between first observation of melting and total melting. HTH :)

Meant to post sooner but been away. Thanks everyone for the suggestions. Has certainly given me some ideas so I guess its time now to get down and play mad scientist and do some experiments. :D

will let you all know how i get on if your interested.
