I’ve been testing to see if I can create a bottom for the 3d printed vessels by pouring slip into the open shape.
I performed this test a bunch of times, and for the most part they have been unsuccessful.

Test 1 print a few hours old, moved from buck onto plaster block, poured slip. Worked but too thin.
Test 2 print dried overnight, moved to plaster block, poured slip. Dried up and broke around connection.
Test 3 print a few hours old, moved to plaster block, poured slip. Cracks around base at connection, but also lots cracking across base surface.
Test 4 bone dry print, moved to plaster block, poured slip. Delaminates a few layers up from base.
Test 5 printed on plaster block, poured base shortly after print finishes. Showed potential but did not work, trying this a second time worked on 12/13 points, might work with better slip.

More pictures to come.
