The CaO should stabilise the mixture

CaO + H2O --> Ca(OH)2
So the CaO will become Ca(OH)2 after the water are mixed.

I tried it with out the CaO too and had the same result as mentioned

sorry for posting in such an old topic but I think I got some information\question to add.

I bought sodium thiosulfate and tried the Improved mixture I.
In powder form it didn't light, I used Ca(OH)2 to replace CaO. when I wetted it a little to make cut stars it started foaming after some minutes and a smell of sulfur (I guess H2S) was coming out of it.
I will wait till it will be dry and try to light it again, but I'm quite sure it won't be very lightable.

Any observations? maybe any one had tried it too?
