ronfire Posted November 19, 2016 Report Share Posted November 19, 2016 Planning on throwing a small sink for the RV. Was planning to bisque upside down on the rim. My concern is the glaze fire to ^6 with stoneware clay, will is slump if I fire it sitting on the small base around the drain? Plan to throw it reasonably thick to put up with the abuse. Should I try to help support the rim on stilts to keep it stable? or throw a ring for the sink to sit in for firing? Plan to clear glaze inside and out except for the small area at the drain to sit on during the glaze firing. My thought is to just fire it on the base with a few stilts just below the rim in case it tips so as not to damage the kiln. Also it would be on its own shelf , hate to waste the room in the kiln but it might be worth it. Link to comment Share on other sites More sharing options...
Mark C. Posted November 19, 2016 Report Share Posted November 19, 2016 I throw them just as I would a large bowl. The only difference is the foot is a larger thicker ring that the is not connected to bowl. The bowl is fired on this ring both green and glaze fires. If the bowl lip is upside down it can drag and warp in the bisque.Just make the sink thick enough so it does not warp. Sinks can be really thick as one installed they never move.

neilestrick Posted November 19, 2016 Report Share Posted November 19, 2016 Just do it like a bowl. The foot can be attached. I do drop-in and vessel types, and make them the same way, just a big thick bowl. Link to comment Share on other sites More sharing options...
ronfire Posted November 20, 2016 Author Report Share Posted November 20, 2016 Thanks, just made one and will trim it when it is ready and hopefully make the next bisque if it is dry in time. Link to comment Share on other sites More sharing options...
Mark C. Posted November 20, 2016 Report Share Posted November 20, 2016 Do not rush sinks-I'm speaking from experience Make another one for a backup as well Trust me on this one. Link to comment Share on other sites More sharing options...

It's a big piece. A standard bowl is 16", which means I have to throw them to 18" to allow for the shrinkage of my porcelain. I use 17 pounds of clay for that, in order to get it thick enough to be durable. I take a long time to get them dry enough to trim, otherwise they love to crack. Take your time...

ronfire Posted November 20, 2016 Author Report Share Posted November 20, 2016 I am not planning on installing the sink for about 6 months yet so it will not be a rush. Link to comment Share on other sites More sharing options...
JohnnyK Posted November 20, 2016 Report Share Posted November 20, 2016 How do you plan to mount it? Drop-in, flush mount (flush with the surrounding tile), undermount, vessel (top-mount)? Link to comment Share on other sites More sharing options...
Magnolia Mud Research Posted November 20, 2016 Report Share Posted November 20, 2016 The most important decision is the answer to following question: Are you making a sink to fit a hole, or will you be making a hole to fit the sink? Given a choice, I would chose the latter. LT Link to comment Share on other sites More sharing options...
ronfire Posted November 21, 2016 Author Report Share Posted November 21, 2016 The sink will be a drop in for a new counter that I will build. I am stripping out my living quarters in the horse trailer and have it spray foamed and then build a new interior. Link to comment Share on other sites More sharing options...
