Try milling a stibnite cristal. That is how get my antimony trisulfide and it works fine for me.
The cristal itself not that hard you can crush it verry easily.

Another country in EU and which country would that be ? Another hint maybe ?
And what about the prices in this country ? Are they low or high?

Hello i have been testing fountains the height is no problem anymore.I reach 5 or 6 meters with 500 gram of formula. The new problem is when i use charcoal in my fountains the stuff immediately covers the al/mg sparks. Instead of a spray of white sparks i only get a orange spay of charcoal. When i use fine al <50 um instead of charcoal i see the nice white sparks of the aluminiun.

The formula`s i used :

kno3 70
C 15
S 10
Al 20


kno3 80
c 10
s 10
al 7
mg 3

The only formula`s wich work well (produces nice white sparks):

kno3 5
al 2 (mix of course and fine)
s 3

kno3 22
bano3 45
S 11
fine alu 11
coarse alu 11

The al and mg i use are about 0,5/1 mm in size verry course. I rammed my fountains.

My question is what is causing this problem ? The ramming ? Maybe the charcoal is to coarse ?
Please help me this is really anoying!

I think this guy is a verry reliable seller!! Check his ebay score 5146 that is a verry high score. But if this scale is a good scale i don t know. But for that price i would buy it !!
