I documented the process of opening up a two part mould straight from casting and preparing it for use. This is a new method for me, as I have always employed open press moulds.
First the two parts are prised open. a release agent is essential for this or only a hammer will be in any way useful (and not for the desired effect!).
You can see the keys in each corner which join the two parts together in the correct place when casting.
The clay is removed carefully, trying not to damage the soft, freshly cast plaster. In my case, as I work in layers, you can see the layers I peel off, one by one.
Then, once all the clay is removed, the clean-up operation begins. For me, this can take hours, because of the intricacy of the forms, I need to ensure there are no undercuts where the clay could get stuck inside the mould. Once this is achieved, the moulds are cleaned.
Now all the moulds are bound together and in the drying cabinet where they will stay for a few days until dry enough to start casting.
