"Try something new and fail quickly" sums up this experiment.

A while back I made ceramic sponges, and at the time I wondered if it could be used to filter molten metal. Commercial metal casting processes do use ceramic filters, so it's not a totally crazy idea.

I probably should have preheated the filters, but I ended up loosing interest after my first try. I don't regret the attempt though...
