I've been trying for some time to get my lead tetroxide eggs to work. I'm using the formula:

Lead Tetroxide 89%
MgAl (30-60 mesh) 11%
NC Lacquer 10%

will potassium perchlorate help at all? I know the dragon egg prime has potassium perchlorate in it... anyone have any other red lead formula?

the comp I'm using is:

bismith subcarbonate 75g
magnalium 200 mesh 15g
copper II oxide 10g
n.laquer 10%

the eggs are maybe 2-4 mm in size.

very hard to light even with a primer.

real loud pop when they do light.


Try upping the CuO and lowering the bismuth. I had good success on my second batch ever using 37.5 CuO, 37.5 Bi2O3 25 MgAl (200 mesh) +10% NC
Reports say subcarbonate and trioxide are interchangeable 1:1.

I haven't used lead in dragon eggs so I may be mistaken - but shouldn't there be some CuO in your formula?

Yes there should be CuO, so that lead formula is never going to work.

You guys must have gotten some bad information along the way. I assure you that an all lead oxide comprised dragon eggs do indeed work. I can't say that I've ever seen an all bismuth oxide egg attempted, but that may just be a cost issue.

With only lead and MgAl?

I think it depends on how you define 'do indeed work', if it's small popping of the MgAl you want, then your right, if you mean an explosion, then you won't get that from that comp. Only sizzling stars.

I got this off of pyroguide and have used the bismuth formula with great results. If you go to the site be sure your anti-virus is up to date, AVG is reporting the black hole trojan there. BTW, I have used a variation of magnalium size and have had good results with all

i followed the comp for the 200-325 mesh mag/al worked perfectly my first batch.and i only used meal-d for the prime.after drying i just spray them with some denatured alchohol and rolled them in a couple of layers of meal-d. simplicity at its finest :D

Yep, I'm fine... Just not in the hobby anymore. I might drop by once every other year or so.

I don't know what you think 3cuo is, but I assure you that it doesn't exist.

I know this is an older topic. But thought. Might throw some input in for smaller dragon eggs.

I tried to make various small eggs with a loud report but struggled through various trials before I got this one right.

Bismuth trioxide 37.5g
CuO 35g
MgAl 7.5g
Al fine powder 5g (I had 400 mesh)

Basically the same as previously mentioned, but when I added the aluminum powder, boy did it change them completely. Very loud report.

Looks like a large one to me :)
Judging by the smoulder phase I'd say the metal mesh size could do with adjusting.

I used to use this formula but found it un usable in the air.

I know it's hard to tell on video but based on the loudness of the whistling, it didn't sound that loud. It also had a really long delay which will make using in a shell hard. Traveling in the air will cool it down which will make getting hot enough to pop, hard. You will need a prime that really holds the heat in, maybe like fence post prime or something with a lot of silicon. If you use a little finer mgal the delay shouldn't be as long. I have had good luck with

37.5 bismuth trioxide
37.5 black copper oxide
25 MgAl 200 mesh

Bound with NC lacquer though I know this thread is about no NC.

It's about 1/4 the size of a pea, one of the scrap pieces. Ill take another movie in a more remote location. The music in the back ground was blaring and I was whistling straight into the phone, so I think the phone equalised the volume down.

Also the shape and lack if prime didn't help things, it was and ice cream come shape, lit at the small end. Either way another video to come should prove my excuses lol
