forgetting "Megalomania's" method for a moment and returning to the COPAE for our common ground (I know that experiment well so it's easy to comment)
- what is needed is an initial solution brought to about 70C - remember they said exposed to steam so they mean a hot solution - is then shook
violently after a period the temp and the shaking is what starts the percipitation. HONESTLY, it has never failed IF the solution is hot and the
shaking, strong. Percipitation of tetrazene starts at about 3-6 hours (the point wherein the temp will drop) and is complete at about 16 hours after
initial formation. The experiment has been scaled up 50% with similar results. - Just my opinion, but typos can have a bad effect on experiments, so
I try mine from source material even if another author like "Megalomania" is just fine in most every case, etc. But in this issue I think it's just a
copy of COPAE. However get your temps to about 70-80 (damn hot solution)  It
will work!

I received 100g of guanidine carbonate from an ebayer recently, and I'm very pleased with the product. I made some guanidine nitrate, and upon
melting it suddently catch fire and burn rappidly. The guanidine will be perfectly suitable for my intended use.
I just specified that because I never saw anyone mentionning its flamability anywhere on SM.
I never asked for this.

The perchlorate of guanidine is another more powerfull beast than the nitrate, it is also very flamable when dry...
With a friend we detonated like 5g inside a copper tube with a tiny silver acetylide -nitrato complex detonator.... it was hell powerfull detonation
for such a tiny amount.

Could you please reconcile your post with these? Specifically the flammability.
