Clay Sculpting

… and from the same sweet youtube channel as yesterday’s lime plastering video comes this demonstration of clay sculpting:

Polished Lime Plaster

Continuing the beautiful work done with clay plaster … this time with lime. I was surprised to see powdered lime being used instead of matured putty (though I’m guessing you can use putty instead … if you have it) … I wonder how it will hold up over time.

One advantage, at least for us, is that lime is easier to colorize then the local clay we use … though I still don’t have a good source for pigments.

I would like to have better tools (= Japanese trowels) for my next plaster experiments.

Shiny Clay Wall Finishing

I enjoyed this video very much – it made me want to get back to clay:

  • It gave me confidence that my experiments in the earthbag cellar were in the right direction – and that with additional refinement, wonderful results can be achieved with earth!
  • It confirmed how important the material mix is in achieveing a good finish (though in our experiments I tried to lean as much as possible on the natural clay-soil we had on site – and in retrospect it needed even more sand than I put in).
  • It made me a bit jealous of people who have access to refined materials … though I am glad to explore with the stuff underneath my feet 🙂
  • It made me reconsider how thin the finishing layers (after base layer) can be – which means much less material to mix, carry and apply! Maybe that also makes it more accessible to bring on-site more specialized materials (I am used to working with tractor loader quantities)?
  • It made me even more curious about experiencing first-hand good tools (like Japanese trowels), I only had the basic DIY concrete-oriented stuff typically available here in Romania.
  • It confirmed my impression that the clay in the mix dominates in terms of color. We experimented with some coloring additives (metal oxides, also readily available in Romania). But it was unpredictable because of the dominant color of the clay. It seems that clay color is key to good, full bodied color!?

Does anyone know of a source for Japanese trowels in the EU?
