Abstract
An ingot mold has a body having an open top, a bottom with an opening, and a longitudinal cavity passing through the body. The cavity is defined by a cavity wall extending from the top to the bottom. The cavity wall has a recess adjacent the opening in the bottom of the body. A ceramic insert is positioned within the cavity such that the sidewalls of the ceramic insert are in the recess in the cavity wall.

A mold for making metal products comprising:
- a body having an open top, a bottom with an opening, and a longitudinal cavity passing through the body, the body having a cavity wall, extending from the open top to the bottom, the cavity being defined by the cavity wall, the cavity wall having a recess adjacent the opening in the bottom of the body, such that material can flow from the open top, through the cavity, through the opening in the bottom and out of the body when the opening in the bottom is not closed;
- and
- a ceramic insert having a bottom and sidewalls extending from the bottom, the ceramic insert sized and positioned within the cavity such that the sidewalls are in the recess in the cavity wall;
- the ceramic insert and the opening in the bottom of the body being sized such that the ceramic insert closes the opening in the bottom of the body when the ceramic insert is in the recess in the cavity wall and the ceramic insert can be removed from the cavity by being moved in a direction away from the open top of the body.
