I took a large pot, put a brick in the bottom, surrounded it with rose petals and filled it with water to just over the brick. Then I put a heat safe glass bowl on the brick and inverted the lid on the pot and put ice in the lid. I emptied it often and replaced the ice when melted.

Does anyone have any idea what I did wrong? Did I use the wrong type of pan? Could my rose petals have been nasty? Is it possible to use the wrong type of rose?

I appreciate any ideas you may have. I have more rose petals, but will not be trying anything else until I change something. Thanks.
