Making the Heart Model Plaster Slip MouldPosted: February 26, 2014
A trip to the plaster room to mould the foam heart model. We have produced a plaster cast which went well with little difficulty. A few things we could have done differently however include:
- Remembering not to make too much plaster – this led to our mould being pretty heavy and quite unwieldy to work with.
- Make a mould with a flat bottom so that pouring in slip and leaving to set is easier, we have to wedge the mould up with clay to keep it upright.
- Maybe put in two access holes, so that the air can circulate through the mould pushing the liquid slip out and not forming a vacuum which sucks in the clay walls collapsing the clay cast.
