Fireworks Help

I am trying to create a fireworks launch pad this 4th of July. I am using 75' of telephone wire to send a charge to ignite this very low gauge wire. That wire will be in the fuses of the fireworks. My issues is I don't know what type of battery (voltage or amperage) to use. I have used a 9v battery but that only work for like a foot of wire. So if somoene could give me an estimate or an idea of a battery that would be great?

There are special ignition batteries available just for this purpose. They are used for launching model rockets. Check with a hobby store.
I'm sure others will be along shortly with more ideas

Most pro systems use 12V or 24V automotive/marine batteries to ignite the electric matches. Do you know what AWG your phone wire is? Something a bit substantial like 18 AWG might be okay, but if it's tiny like 22 AWG or 24 AWG your wire might not be adequate. What type of ignitor are you using?

Something to be cautious of is that you must keep the battery end of the wires twisted together (shunted) until right before you're ready to ignite. If left untwisted, radio frequencies like those from cell phones can cause premature detonation of the electric match.

Model rocket ignitors and 6v lantern batteries would probably work.

I used to do theatrical pyrotechnics, and this was a very good source. I'm sure their equipment is not intended to be used with outdoor fireworks... but... well, you know.
