    Undergrad Why is water pressure increased in a plastic bag in a bucket?

    Putting this together with the next paragraph, then it seems to me that B should work if there is some air left in the bag so the top of the clay is in that air pocket. Is that right? So D would depend on the bag not being filled completely and having air in there?

    Wow! Thank you for all the replies. I'm still going through them. I have done some quick scanning. I don't have much in terms of equipment and I'm surprised this wasn't just something with a simple answer! I'm not complaining - I just was sure there would be some simple explanation about...

    I think you're thinking along the same lines as @256bits with that - what makes the water different chemically. Playing the devil's advocate here, but I can think of 2 points that might indicate that the used water is an issue is that I would think that leaving the clay in for 48 hours or so...

    Small point - what I'm doing is basically what a lot of the local potters do, so you could say I'm following "tradition" or "local lore." I haven't, but I know others who have. I also have not tried different amounts of water in the bag, since others have said, "This works," and I tried it and...

    Good thought, but the water is from the same source. I know when I do this, I fill the bag, tie it off, then fill the bucket. And since it sits for about 48 hours, in my studio, it's at room temperature. ------ Added: ----- I wrote a long edit to this reply that got deleted - which may be just...

    Undergrad Why is water pressure increased in a plastic bag in a bucket?

    I'm not a physicist or even a physics student, I'm a pottery student and there's a conundrum that's been puzzling potters in my area for a while. We've found that if a block of clay dries out, the fastest and best way to revitalize the clay is to put it in a bag of water, tie the bag so it's...

    Hi! I don't know how active I'll be. I came here with a specific and it's too simple for some forums and too complex for others! I do hope I'll find more and more here to explore as I look around!
