Here is an example of one that was for sale on Ebay. The inset bottom will be a challenge, for version 1 we will likely settle for a flat bottom.
No molds have survived so we are going to start from scratch. We will use Fusion 360 and 3D prints in PLA to create a block mold to make a rubber case mold. Learning to draw this rewarded me with some new 3D drawing skills. The geometry of the lip is challenging. It appears the piece will need to be cast with a full top and the lip shape and pouring hole cut manually (as was done originally at Medalta Potteries). I will likely have to create a 3D-printed PLA template as a cutting guide to get the lip contour more correct and consistent than they were able to do. Although not on the original, we are going to include a foot ring for easier glazing and better stability during forming and firing.

Medalta Ball Pitcher Slip Casting Mold via 3D Printing
A project to make a reproduction of a Medalta Potteries piece that was done during the 1940s. This is the smallest of the three sizes they made. |
