project#4: the ceramic exhaust
For a while I have kept myself busy trying to make a ceramic muffler/exhausts. Technically I should be possible for it can stand the heat. Esthetically it could be mind-blowing, just throwing on the pottery wheel any shape you like.The only challenge is to find a solution for the vibration when you driving, but my guess is it is possible.
My first idea was to make it a cast porcelain exhaust.The bright white in contrast with the black soot.
So far I've made a casting mould and casted a few,but the shrinkage of 16% and the total height of almost 60cm didn't give any usable result.
The next step is to press mould a few with a low shrinkage clay. I have to try and keep the walls thin and strong.
