24k or 23K Gold foil?

Just recently I was in a store, and many of the sterling silver
pieces had gold foil on them. I think the technique is called
Keum-boo(sp ?). Would like to try it, need to know where to purchase
the gold leaf, Rio Grande has 23K is that ok, or should I keep on
searching for 24K? Once the foil is placed on the finished piece, do
you heat it and then burnish it? Thanks for any Jill
