fruch Posted October 13, 2015 Report Share Posted October 13, 2015 My high school students want to start making larger bowls. I myself and more of a handbuilder/sculpture ceramic artist. I was wondering how many pounds of clay per inch when making vases, bowls, plates, etc. I know the type of clay, water, and thickness will all play a part. But, in general what is the correlation?

Min Posted October 13, 2015 Report Share Posted October 13, 2015 It's not lbs per inch but this might get you in the ballpark (page 6) http://ceramicartsdaily.org/wp-content/uploads/2009/10/cadbg10.pdf Link to comment Share on other sites More sharing options...
neilestrick Posted October 13, 2015 Report Share Posted October 13, 2015 It's not a constant amount, because as pots get bigger they also get thicker, and the proportion of clay in the bottom vs. walls also changes. It also depends on how wide the piece is. I can make a 4 pound pot that's 14 inches tall or 6 inches tall. Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted October 13, 2015 Report Share Posted October 13, 2015 i like Min's reference. The first dozen or so aren't going to make it quite that big, but it's a good place to start. I find if you're going to try bigger items, it helps to do the bulk of your wedging the night before while the clay is soft, and leave it uncovered to stiffen up. Wedge it just enough right before throwing to wake up the clay and get the moisture level even. Link to comment Share on other sites More sharing options...
