In Topic: Burner Placement In Kiln Design

28 April 2015 - 05:33 AM

I have a top loading gas kiln. The burners fire upward, so they are underneath the floor. The door is the roof and has a pulley to raise it. I have to climb stairs to set it as I am short, but I don't find it difficult. It is still easier than holding a shelf out in front of me. Setting a top loader is much easier on the lumber region and the setting can be seen from three different angles. I do find that I have to put my weight on the walls, which are brick, lined with fibre. If I remake it in soft insulating bricks, I will have to find some way of supporting myself, other than the walls.

I know of a 10 cubic foot kiln that has two gas burners firing upwards on either side of a brick flue. It is front loading and fibre lined, except for the flue, which is only as high as the kiln itself. The flames just hit the fibre roof, with no ill effect, and it has no bag wall. Its owner, who has been using it for 35 years, says that the bottom is a cone cooler than the top but that is fine. She just allows for it.

In Topic: Turned Foot Rings On Mugs; Elegance Or Affectation?

15 April 2015 - 11:04 PM

I don't like washing bare clay on domestic ware whether it is for serving or cooking. So I cut foot rings. They look better and allow most of the base to be glazed. The only disadvantage of the foot ring is its tendency to collect grotty water in the dishwasher. I cut V shaped chinks in the foot ring, but that spoils the look. What I would like is the foot ring on a plastic mug I own. It has a foot ring of tiny half domes, but I can't think of any way to apply them efficiently to thrown cups. Any ideas?


In Topic: Water Source In The Studio

I have a tap outside my pot shed, but no delivery to a sewer or septic tank. Throwing and hand building requires very little water. A bucket for washing tools and hands, and a bucket to collect the wheel washings. I also keep several plastic soda bottles filled with water at various points around the studio for when I need clean water.

The process of glazing is a different story. It takes plenty of water from the hose, but I can't send anything to the septic tanks. My lawn is my glazing area and I use the hose as a pressure cleaner. All the water goes directly into the ground. As Western Australia is very dry for half the year, the lawn likes it just fine.


In Topic: Round Measuring Tool?

Graphic designers usually have the software to print out paper with lines radiating from a central point that divide a circle into fifths or sevenths or whatever. 380° is divided by the number of divisions,  and a line is rotated by that number of degrees.  I think you could get fairly even divisions with a plastic protractor.
