Abstract

1333707 Slip casting ceramic material JOHN STEVENTON & SONS Ltd 18 Dec 1970 [2 Oct 1969] 48496/69 Heading B5A To facilitate removal of surplus slip from the interior cavity 16 of a ceramic article, formed by slip casting in a plaster of paris mould, and to avoid displacement of the cast material 15 from the mould surface during removal of the surplus slip, air is passed into the cavity 16 through a hole 10 from an inlet 9 while the surplus slip is being run off through outlet 8 in the lower part of the mould. In the mould shown, slip is passed into the mould from a hopper 6 through an inlet 5, and vents 17 are provided in the top of the mould to ensure that no air is trapped in the mould cavity. Valve means 13, 14 are provided to control the air inlet 9 and slip outlet 8, the air being introduced under pressure from a blower 12. In an alternative embodiment (not shown), air may be introduced at atmospheric pressure through a flexible tube passing upwardly into the mould cavity.
