Abstract: A slip casting apparatus comprising a supply tank, a reserve well in communication with said tank, a pump means to pump said slip from said tank through a delivery means to casting molds and having provision for continuously recycling the slip in and out of the supply tank. The same pump is utilized both to deliver slip to casting molds and to recirculate slip within the supply tank, in a manner which eliminates settling and relieves the pump from undue pressure. This apparatus has application for use with other liquids of similar characteristics. The well also functions to prevent the formation of air bubbles.
