How to crackle paint...?

I brought some red plastic chargers from the holiday section of Wal-Mart and I want to crackle paint them using a bronze color so that there are red veins running through the bronze. How do I do this?How to crackle paint...?
Surprisingly crackle paint can be bought. I obtained some in an artist's supply store.How to crackle paint...?
being that you have your base colour already you simply apply the crackle then apply your bronze colour over it and your crackle will appear. just read the can from the crackle and it will explain it. you might want to apply a urethane over top for protection but do not apply a water based urethane or it will crackle also.
