glazing outdoor ceramic pieces
Posted 21 April 2013 - 02:18 AM
I painted a bisque piece at a studio recently and they glazed and fired it. I noticed when I went to put the piece in my garden that the inside of the piece still had that chalky bisque feel to it. I didn't paint the inside. I thought they dip the whole piece in the glaze (inside and outside), not just the outside painted areas before they fire it. That way the inside would be smooth and shiny like the outside painted parts.
Is this a normal procedure for outdoor pieces? Won't this cause a problem with moisture getting inside the piece since the bottom of the piece has a big opening and will be sitting in the dirt?. It seems like it would eventually disinagrate or the paint would separate from the piece.

Many people have pottery gardens, and these pieces both glazed and not.,and sitting in the dirt will out live many of our life times.
Glaze may make clay water resistant, but can also cause physical problems.
Much depends on sentence one.
There will be other along with more scholarly response.

It is best to use a freeze resistant clay. There are terra cotta recipes for this.
