Zumber Posted March 27 Share Posted March 27 If you are begineer and new stay away from flash. Read flash powder safety notes first. It works well but stay away if you dont have experience. Link to comment Share on other sites More sharing options...

I know that I should use the diaper method stay away from electronics and metals use PPE and anti-static and be very gentle with the powder isn't it enough?

Zumber Posted March 27 Share Posted March 27 Then dont just attempt to prepare any kind of flash. Any Flash powder is extremely energatic and detonates if confined burns at extreme speed in open and friction and impact sensitivity and most important is aluminium powder. Stay away and try out black powder type formulations. Its not the right time to go for flash. Link to comment Share on other sites More sharing options...

Are you sure HE means explosives that travel over 5000 sq km per second and produce gas too Link to comment Share on other sites More sharing options...
