It was glued down using the casting slip itself (it stuck in seconds). About ten minutes after draining a fettling knife was run around the inside, then it detached easily. The overhung lip produced imparts structural strength, for drying and firing, to the thin walled piece. This spout has advantages over the traditional "spare" built in to the upper part of a mold. It enables a one-piece mold. The lip can be more overhung. Draining is cleaner and easier. Molds are lighter. Extraction can be done sooner and it is easier. The spout does not absorb so there is less scrap. The degree of overhang is adjustable by simply printing new spouts.
