Hi!

I wonder if it's safe to use copper plated leadballs as milling media?
I've read on some pages that copper dont spark, and on other it says that it dose..

my chemicals were "ready powdered" when I bought them.. So I just screened them together to break any lumps.
I haven’t got time to make CIA stars yet.. but tomorrow I will

edit:
another fast question, I have two types of charcoal, one air float super fast charcoal and one not so air float, maybe 100-500 microns made from BBQ charcoal. which is to prefer?

It is chrys 6 stars.. and well,, MDH the stars are less then 1cm squares and maybe 0,5 cm thick and glow for half a minute
And it's not the sparks that glow, it's the star itself that glows after all the sparks has been "send out"...

I'll try making them using the CIA method as soon I have time, and hope it works better

You will need to ball mill streamer comps or use the CIA method to incorporate the Kno3 into your comp,or you will get the problems you are describing and a poor star,

yea.. that might be the problem. guess I'll have to try a new batch and see. I tried shooting them with a higer speed, same thing happend.

thanks all!

i've both tried on the ground and small mines.. but maybe they don't travel fast enough to burn then.. I'll give it a try with more lift tonight and see.

thanks for your reply
