Did I just discover a new strobe comp?

[stug161]

I came across a pound of Mg/Al in the 700 mesh range pretty fine stuff Thought I would try to do something good with it. I mixed up one gram of it, with one gram of granulated sugar, and added two grams of Strontium Nitrate. I kind of mixed them together, and tried a small amount. It of course flashed too quickly, although it was super red. So I decided to try something else. I added some vaseline.. It takes fire pretty easy, and it strobes at a fairly decent rate. Is this a new find? It seems kind of inconsistent, and that may be due to my lack of good mixing..

 

Thanks, Robert

Strontium Nitrate / MgAl strobes are well documented : )

 

I've made a few myself via experimentation but there are a few tried and tested formulas here:

Lots of good information there! Thanks. My biggest deal is that I was using -650 Mg/Al, and was still able to get a decent strobe. I know there is a big difference between my 30-60 and my 100-200 and this stuff is 600-700. I didnt think it would actually strobe at all. Im going to work with it a bit more this evening.

 

Thanks, Robert

Cool, I'd be interested to hear the results. That is pretty fine stuff to be getting a decent strobe from - what kind of strobe rate are we talking here? Is it more of a shimmer than a strobe?

It was fewer than 1 HZ. I would say it was probably 3 part comp to 1 part vaseline. Again, it may just have been a clumpy pile that was intermediate burning, but it did seem to be fairly steady. I will have more info by morning.
