cstovin Posted September 10, 2012 Report Share Posted September 10, 2012 Hi all I know raku glazes are not fired hot enough to make clay non porous; or better said the clay after firing is still porous. I want to make a water fountain and I love the metallic results that various raku glazes/firing work; can I go ahead and fire my raku pieces for a fountain and use like a polyurethane coating to make it water resistant? Any ideas appreciated... Thank you Charlene Link to comment Share on other sites More sharing options...

Any ideas appreciated... Thank you Charlene I make bonsai pots. We need a fully vitrified pot...so I learned from a german potter who fires to stoneware temps then raku, that it is possible and good results can happen...expect losses...lol http://www.hhpots.com/Rakupot.html Link to comment Share on other sites More sharing options...
Benzine Posted September 11, 2012 Report Share Posted September 11, 2012 I was going to suggest the same thing. Just fire the clay to the full temperature first, then glaze and raku. The glazing will be a bit more difficult, as the glaze won't adhere as well, but I don't know why it wouldn't work otherwise. Link to comment Share on other sites More sharing options...
Chris Campbell Posted September 11, 2012 Report Share Posted September 11, 2012 I would not expect the metallics to last very long outdoors in the sunshine ... even the waterproof coating has to outlast the sun, water and weather. You might get a result to last a year maybe? Worth it if it's gorgeous and you don't mind re building it. Link to comment Share on other sites More sharing options...

Actually, I was just going to maybe try to make some small indoor ones; decorative and small water feature for desktop or table top....we used to have something made out of planters that was indoor, and I loved it....so was just thinking...thanks all Charlene Link to comment Share on other sites More sharing options...
