I'm making a frame for a ceramic hotplate. Basically, just a few small ceramic tiles glued to some wood. There's going to be a solid wood border which will not be in direct contact with the hot thing on top (at least I hope). I was wondering if I could use poly-urathane, or such as a finish. Also, the piece will be held together by tongue-and-grove, with glue. Is regular carpenters glue good for this sort of thing?
Thanks
John
