That's a good point. If I ever get some motivation I might try putting a hose and a quick connect on my kiln. It would be interesting to try, at least. But I also don't know what I'm doing. I've never cast metal before. Watched plenty of Youtube videos on the subject. Kinda like reading a book on how to swim.
