Tea for Two – Plaster workshop

Working continuously for over a week in the plaster room to create plaster prototypes from my textile stitched cups and then plaster moulds for slipware.


Textile cupAs I wanted to explore the holding and containing abilities of a tea set, and possible absence of it, I looked at shape created by the act of accommodating.
I chose textiles and stitch as it’s another object associated with home and domestic environment. Available at my house too, I spend few late evenings cutting shapes and stitching them together to govern the final shape to some extend, to at least appear like a cup or a teapot.

Filled with plaster, even thought the textiles forms were assembled from number of parts to hold the shape, the plaster was much heavier and overpowered the stitches.
In some cases I had to hold the shape until the plaster hardened, or supported them with boards, strings or in a container.

At the end I ended up with fairly large amounts of prototypes, as the teacup moulds were open, allowing me to separate the plaster and textile without the need of ripping it, as necessary with other textile moulds. I was free to experiment with the way they stand and fold, turning them inside out, bounding them with string, etc.

Attempting for a smaller components such as spouts and handles, which are trickier.
The only worry is how much they will shrink in the kiln as a slip cast, and being able to pour.

The hardest and most time consuming part was creating the 3 plaster moulds for slip casting.
With highly irregular shape, I had to look for many undercuts and divide the shape into 4 to 8 part moulds.

However, taking every opportunity to work in the plaster room, I managed to produce the 3 fairly complicated moulds in about a week + extra day or two; getting essential skills at more detailed plaster mould making. Of course through many mistakes too.
