Reduction Vs. Oxydation in Raku Firing

Two pots were fired in the same kiln. One pot was taken out and put into a reduction can. Immediately afterward, the next pot was taken out and put into a separate reduction can. Both cans were quickly covered with lids. The two pieces were both glazed with copper sand.

Q. Why is the first pot copper colored and the second rainbow colored?

Glaze Application Tips

So many choices. Where to begin? Let's think about the proper application of one glaze to a bisque fired pot. Form is everything, with or without glaze, but glaze can make or break a pot. The best way to learn is to watch an instructor or an experienced potter glaze a piece. This is how one learns what is enough and not too much, a common and costly error. Here are some tips to help.

SLAB ROLLER

We have a new slab roller! And it requires a different technique than the old one. The new roller has a moving tabletop with a canvas attached to it. This tabletop moves through the roller, and is designed to move in either direction. The canvas attached to the tabletop should never touch clay. Instead, take one of the canvases that we used with the old slab roller, put your clay inside this canvas, then lay this canvas on the tabletop underneath the attached canvas.

Itís important that everything be smoothed out and that the moving tabletop is aligned with the fixed tabletop so that it will go through the roller straight. Then use the wheel to run your slab through the roller. If the moving tabletop starts to go crooked, gently adjust it so it is straight before finishing rolling.  As with the old slab roller, itís important not to pound clay on the tabletop, which can knock the roller out of alignment. Use the wedging table before putting your clay in the canvas for rolling.

Use of the HPG Grinders

The HPG grinders are intended to remove small amounts of extra glaze or other imperfections in finished work. They should not be used on bisqueware, nor should they be used to remove lots of runny glaze. If your pot has a ton of runny glaze, please throw it out rather than wearing out the grinder trying to fix it. If you use the grinder, wear protective gear (eye cover is essential, respirator a good idea), use the rough wheel first, then finish with the fine wheel, and do not push too hard against the grinding wheel, it tends to leave a groove and does not improve the quality of grinding. Also, please be very careful not to damage the power cord when you are grinding or when you stop grinding. Make certain the wheels have come to a full stop before winding the cord over the grinder and putting the cover back in place.
