Congratulations!
Bronze are an ideal fish to begin breeding with. They are hardy, ready, and frequent breeders. They also can usually find homes.
Their eggs are some of the easier to harvest too.
I use a breeding net for the eggs. I keep one hanging in the tank of breeding Cories. But if you do not have one, anything that holds water with do. As was said above, a heater and an airstone under the eggs. My first try I just lifted out an artificial plant with eggs on it and put it in an empty Eclipse 3 with a heater and an air stone. After a few days they will hatch and then they will eat the egg sacs for a few more days. If you can get Liquid Fry or Hikari First Bites, they can start on that when the egg sacs are gone. The biggest danger is fungus which comes very often from uneaten food, so it must be cleaned out and not left often. After a bit you can give them fry powder or grow your own microworms.
All of this is the easy stuff to get that I am suggesting.
There is a detailed pinned thread at the top. Read several methods, because one will work for you and your situation, while others won't.
