1.I like the Aalto vase, so make the volume similar to it with the plastic film.
2.When I made the slurry as the recipe, it seemed very dry and cannot pour down at all. So I added more water little by little. Finally the weight was 500 g. And I added 15 g blue pigment.
3.Cause I didn’t find the right aggregate, and didn’t sieved it very well. When I poured the final slurry, it was just on the surface.
4.The result is it. I think the reason is that the size of the inside aggregate is not coarse enough for the flow of slurry.
