      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.

Strange brown specks !

Recommended Posts

Hi all

If anyone can identify these funny brown specks I'd  appreciate it.

They are on a white earthenware that I had fired up to 200C  over a few hours and then candled   I did this to eliminate the moisture as I had had big problems when firing before with explosions.

I usually just bisque fire and haven't noticed these specks before. The slabs are resting on silica sand which I haven't used before either. 

Thanks Julia

Just as an aside, 200C / 390F is awfully hot to be candleing at. (around  85C / 185F and up to 93C / 200F works for me)


I agree. The purpose of candling is to drive off the water before it has a chance to turn to steam. Once you're above 100C you're not really gaining anything by holding temp there, and the chances of blowing something up greatly increase.
