Coffee Soap and gel vs non-gel

[BlueValkyrie]

Hi sermunke

I'm not sure what your rice milk containers are like. The milk cartons that I use don't have any aluminium - they're just cardboard, and the inside is white, and sort of lined/sealed with very light clear plastic if that makes any sense?

My juice cartons on the other hand (which I don't use) have an aluminium foil lining - when you open them up you can very clearly see that they are foil lined. They are also much harder to tear.

I would just rip a carton open and examine it I suppose - or maybe if there is recycling information on it that may help?

I have experimented with the foil lined ones. There is a layer of plastic OVER the top of the foil, so it's hard to tear off, but it makes NO effect on the soap that I've put inside them at all. If in doubt, try it with one and see what happens, just remember to stick it outside first, as your cardboard containers might me manufactured differently to ours here in Australia? But I've had absolutely no trouble with using them at all, and use them as the molds for my classes to take their soap home in after they've made it.

That's interesting Shadowdancer - I had wondered about the plastic coating on the foil lined ones.

As a newbie, I had read up and found out that lye reacts with aluminium, and therefore steered well clear. However, I have no idea what actually happens

Soooo....what does happen?

I dunno what happens so I will give it a go here soon. If something exciting happens I will be sure to tell you about it and post pics :wink:

I think the containers are plastic lined. I will be making a batch soon, I have been on break until my stock runs down to an acceptable level :wink:

It has never occurred in any soaps that I have made yet in any of those containers at all and I've been making soap for over 10 years .... the reaction between Lye and Aluminium results in Hydrogen Gas. I have heard of it happening to some people who are not aware of it, but it's never happened to me ever.

Hydrogen gas does not sound good :shock:

I will try it carefully at some point - outside as you suggest Shadowdancer. Let us know how you get on Serfmunke...and post pics
