Hello, I've been interested in pyrotechnics for a long time and I wanted to try my hands on making some bp.

My initial plan was to use glass marbles as media but I read that they can still spark and that the only accepted safe option is lead.

However I'm concerned about lead poisoning and so I'd like to know if there really are no alternatives.

In addition to this, if there really isn't any alternative to lead, os there a way to harden the lead media surface to reduce lead abrasion ?
