Glazing Tutorials in pictures

This first tutorial shows a large coil built bowl being glazed.  

Wax Resist is applied to the bottom of the bowl and approximately 1/4" up the side.  The wax resist keeps the glaze from sticking to the clay where it is applied.  You need an unglazed surface for the piece to be fired or it will melt to the kiln shelf

 

White glaze is poured into the bowl while being held over a large pan to catch the extra.

 

The bowl is "rolled" to cover the entire inside with the glaze.

 

The extra glaze is poured into the large pan while turning or rolling the bowl in an effort to get as much of the rim of the bowl glazed as possible.

 

The glaze that dripped on the outside is sponged off so that the glaze layer on the outside will be uniform.

 

The top edge of the bowl is dipped into the glaze to cover the places that did not get glazed when the inside was poured.

 

Preparations for pouring the glaze on the outside.  The glaze was poured out of the large pan and back into the glaze bucket.  A tall plastic jar sits securely in the center of the large pan and a piece of foam is on top of it.

 

The bowl is placed upside down on the piece of foam.

 

Glaze is poured over the outside as carefully and evenly as possible.

 

Continuing to pour the glaze

 

The excess glaze sitting on top of the bowl (the bottom of the bowl) will be cleaned off.  It won't stick to the bottom because it has wax resist painted on it.

 

One week later, the bowl has been fired in the gas reduction kiln.

 

The light coat of glaze allows the texture of the bowl to show clearly,

 

Notice how the clay that looked almost pink after it was bisque fired is now a dark red because of the iron content.
