      Moderators needed!   12/08/2017

      Ceramic Arts Network is looking for two new forum moderators for the Clay and Glaze Chemistry and Equipment Use and Repair sections of the Ceramic Arts Network Community Forum. We are looking for somebody who is an active participant (i.e. somebody who participates on a daily basis, or near daily) on the forum. Moderators must be willing to monitor the forum on a daily basis to remove spam, make sure members are adhering to the Forum Terms of Use, and make sure posts are in the appropriate categories. In addition to moderating their primary sections, Moderators must work as a team with other moderators to monitor the areas of the forum that do not have dedicated moderators (Educational Approaches and Resources, Aesthetic Approaches and Philosophy, etc.). Moderators must have a solid understanding of the area of the forum they are going to moderate (i.e. the Clay and Glaze Chemistry moderator must be somebody who mixes, tests, and has a decent understanding of materials). Moderators must be diplomatic communicators, be receptive to others’ ideas, and be able to see things from multiple perspectives. This is a volunteer position that comes with an honorary annual ICAN Gold membership. If you are interested, please send an email outlining your experience and qualifications to jharnetty@ceramics.org.

Firing a lighter load

Recommended Posts

Of course, poor planning, but....I need some pieces to get throught the system soon, and don't have a full load for either bisque or glaze. I know a lighter load fires hotter, so any advice on what adjustments to make?

 

A friend with the same kiln as mine bisqued a light load with the same schedule I use and he got a cone hotter, and had trouble getting glaze thickness to stick.

I have run into this problem, so I use all extra shelf supports and have learned to keep a half-dozen hard bricks on hand to fill in and help hold heat. It sometimes takes longer to get to temp, but if you have a digital kiln and work your firing schedule by temp, not time, you shouldn't have any problems.

Heatwork is heatwork. If you are using a digital kiln, it will heat at the same rate in a particular program whether you are firing empty or full. It's not like a manual kiln where it will fire faster or slower depending on how full it is. It will ramp up at a specific rate no matter how many pots are in it. The problem you may have is if your kiln only has one thermocouple, your load will fire more unevenly because it is not as full. Make sure you distribute your work throughout the kiln, but tighter in the middle.
