I chose the yogurt method. It's super simple and Martha says it will give you the most natural looking patina. For a true test, I started out with some brand new pots which you can pick up at any garden center for under $1 each. Basically just slather yogurt all over your pots with a foam brush and set them outside in a shady area.
I bought plain old yogurt.
And then put my pots in the shady corner of my front porch.
Hopefully I'll see results in a few weeks. I will keep you posted!
I do have some yogurt leftover. I think I'll try this on a batch of my older pots to see if that makes any difference. In the meantime, I don't want anyone to eat my experiment.
Hmmm, we do have lots of squirrels and other critters in our neighorhood.
I wonder if they like yogurt?
