Indian fireworks are poor quality.

You are pretty accurate in your assessment.

I don't see arsenic as the holy grail of elements (Yet, anyway) for a few reasons.

There has been no documented case of a pyrotechnician using arsenic oxides or realgar to intensify colors, both of which would presumably intensify colors without a chlorine donor (Think, barium nitrate, potassium perchlorate and realgar).

My other question is - how does Arsenic transmit chlorine to copper within a flame envelope? If it forms chlorides at a high temperatures that prevent chlorate from being reduced to chloride, wouldn't another element which behaves similarly suffice?

Just out of curiosity, what exactly is it that you believe Arsenic will do that other elements won't? What specific chemical reactions occur with arsenic in a flame envelope?

I'm bumping this topic to show you all a fairly interesting video posted by a russian forum member.

Again, this demonstrates how in the right environment, copper produces intense blue at very high temperatures:

Is it really even necessary to ram it? I have made waterfalls before out of barium nitrate / aluminum / paraffin compositions and all of them were pressed, not rammed.
