dgsh009 Posted January 2 Posted January 2 (edited) Hello dear friends and happy new year I made some bp with cia method after drying, screen it with 100 mesh screen. but the bp comp is insensitive to flame(burn after 2-3 seconds after touching the fire) and burn not fast. Could you help me please? Edited January 2 by dgsh009
Zumber Posted January 3 Posted January 3 From your previous posts what type of charcoal and potassium nitrate you have used? Can you post video of test results? You really need to read books and study well.
FrankRizzo Posted January 3 Posted January 3 CIA method will always result in inferior powder. It's simply an expedient way for CIA to make a low-performing explosive. It may work for your fountains, but you've completed ignored any advice provided to you. Get f**ked.
dgsh009 Posted January 3 Author Posted January 3 (edited) Thanks my friends for your answers. I send my bp test here. I studied reliable pyro sources such as shimizu's,lanchaster,westech,AFN,... books and magazines and sites skylighters and many others. I make this by cia method. In the test plate we see some white dots remain(in the photo indicate by red circle). What are these? I see many tests but after burn bp remains nothing only little black. Are these white dots chemical products of burning BP reaction? (such as Potassium carbonate, potassium sulphate) What do you think ? Edited January 3 by dgsh009
dgsh009 Posted January 3 Author Posted January 3 (edited) this is my video test. Before i record this video i take a flame near my bp for 2 seconds and it wasnt ignite so cut the video. In this one (uploaded here) it ignites and burn moderately good( in my opinion). I guess the maybe reason of failure of fast burning and sensivity is moisture of charcoal.(But i made charcoal myself and place in dry place without humidity) Please give me your comments and hints my friends about this. 20250103_131504.mp4 Edited January 3 by dgsh009
Zumber Posted January 3 Posted January 3 (edited) If you have studied from books, don't you even know how to follow safety precautions? You are igniting loose powder with cheap lighter which might blow your finger even hand and hurt yourself. Safety first is most important thing in this profession ,another weird things is why you are placing powder over that plate? instead ignite it over clean ground surface using visco fuse or piece of BM. White dots might have seen from white plate background can't say much about that. Did you observed any bubbles during burning ? which may be result of presence of moisture in it. How long you dried bp? Remember loose powder burns slower than granulated bp. Your powder sound a bit good; ball milling is best option and you have to use finely grounded chemicals. If your charcoal is homemade how fine it was? What type of wood shavings you have used? Edited January 3 by Zumber

What type of wood shavings you have used? okay.Yes safety is very important for me. but here i want to record a sample test as soon as possible. and the sample was very little. My charcoal is made of Lump Charcoal( no briquetts). other chemicals are industrial grade. I dry it for 3 days. i dont see any bubbles during burning. white dot is melted and remain. the red circles is indicate white dots in the below photo perfectly. Edited January 3 by dgsh009

Could you help me please? How much time did you spent for drying? May be it is not dried completely. You must thank yourself as it didn't ignite else you would have burnt your hand completely. Always test it with a fuse. Even if you use a fuse for testing 3-4gm of BP the fuse should be of such length so that you can get to 15 feet away. Seems you lack basic safety precautions. To understand whether a composition is completely dried put some composition into a transparent polybag, fasten it and keep under the Sun. If you see bubbles after some time at the inner surface then the composition needs further drying. You are questionable of grade of Charcoal & KNO3. A lot of discussion has happened in this forum for making effective Black powder, go through them diligently. Advices are for your safety & betterment.

Zumber Posted January 4 Posted January 4 That could be the sign of not mixing all three ingredients homogeneously. If you ball mill you will see the difference.

Richtee Posted January 5 Posted January 5 Not near well enough mixed/incorporated. Those white balls are the nitrate not full reacting in the mix. Get a ball mill. BP.mp4

deepakpyro Posted January 5 Posted January 5 (edited) 37 minutes ago, Zumber said: Loose powder or granulated? This is loose BP powder, which i was tested long time back. This one is ball milled for 2 hours i beleive (couldn't remember exactly how many hours of ball milling) and charcoal is home made. @dgsh009 from your video you can clearly notice long hanging charcoal flames and also slow burning both indicating the charcoal is not fine enough and the BP was not homogeneously mixed. Try to seive through fine mesh (100 or 120 mech seive) for atleast 3 times and make granules and dry for atleast 2 days is climate is moderate. Edited January 5 by deepakpyro

I read some refrences that sieving method works good enough. so i use screen mixing(3-4 times 100 mesh). My charcoal was lemon Lump charcoal.( it was stored in warehouse from 2 years ago).

Zumber Posted January 5 Posted January 5 (edited) You have made lots of post on this and still you are confused. You must have all ingredients used are finer enough, pure and mixed well with finer sieve and most important thing is you have to mill it. Then you can granulate it either by pressing/Corning/granulating using screen and dry it very well. Please do watch video tutorials on this. Then again try it. Edited January 5 by Zumber

It will not be much workable if you intend to lift shells. The burning has to be more faster for this ocassion.
