We choose to work with cardboard to create a precise shape made out of “mountain” and “valley” folds. We wanted to work with a small shape to keep control over the materials and the shape. Too big of a size would probably become more unstable and also require a big amount of slurry and pebbles. Too small of a size could make it hard to make folds and also create a risk of slurry not entering all gaps.
We did not get a clear picture of what would be a good size and mix between peeblestone and slurry.
What is relevant sizes according to different sizes and shapes of mould shape?
