Has anyone had any luck with TH3 thermate? I tried it once and the performance was garbage. A quick fire that just left a burn mark on the test plate. Same amount of thermite would have left a small hole dripped through.

Thank you VERY MUCH

I do appreciate it! I have a paid app CamScanner that I pay like $70 a year for since I constantly need to create various pdfs. I was able to load this piece by piece on there and merge them into one volume.

Hello everyone, I have a question and this seems like the thread to put it in. Someone here mentioned that aluminium-sulfur thermite is easier to ignite than the standard iron oxide thermite. thermite made from coarse aluminium powder is very hard to ignite, especially with the low quality sparklers. I had the idea to melt aluminium sulfur thermite made with a finer powder, and dip sparklers in it, to create a sparkler which would hopefully burn hot enough to light very coarse thermite. I am also aware that handling a molten thermite sounds like an incredibly bad idea, but the theory is that the melting point of sulfur is about 115 degrees celcius, and this is far below the ignition points of most thermites.
Does anyone have experience working with this?
Also, would the sulfur just oxidize the aluminium?
Lastly, some mixtures, like whistle mix, can detonate when molten. could this happen for a molten thermite?
Thanks everyone.

I have not tried this, but my prediction would be that it would not ignite below 500 C, so you may have some room to move there. Best to try it on a very small scale first. Also you will need to check that molten sulfur will not react with the perchlorate in the sparkler on contact when you are trying to coat it. Another option is a mixture of a perchlorate salt and aluminium bound in silicon sealant. It burns hot enough to ignite aluminium/iron oxide thermite.

I once experimented with an Aluminium-sulfur mixture, and it quickly melted through a stainless steel can, so I would say it is almost as hot as the thermite itself.
For mixtures of sulfur and metal powders, the ignition temperature is between 400-600°C.

This paper doesn't list an aluminium-sulfur composition, but I doubt its ignition temperature would be significantly lower than the magnesium-sulfur mixture.
I haven't measured the temperature exactly, but from the combustion tests I have done, they seem to behave similarly in that matter.
When testing a large quantity of the Al-S mixture, I had a steam explosion happen, but I really don't think it could detonate on its own. But you should try it out in safe quantities before messing around with it.
One problem there could be is that it might be hard to form a homogenous mixture from the two.
