Beautiful work. The "Vases with Eagles" makes an interesting counter point to the other pieces in the show.


In Topic: Voltage

Do you mean for rolling your own elements, or just calculating firing costs?

 Mostly rolling my own.  I want to max the allowable amperage so I get the fastest ramp possible at high end. Right now I can just barely pull 100F / hr.

 

Also, doesn't the resistance increase quite a bit at high temperatures?  I never saw this calculated in.

Neil, I noticed that when the kiln elements on my kiln are on high range that the voltage drops almost 8 volts from no load. So, should the lower voltage be the one you use to calculate amps and watts?


In Topic: Achaemenid Glaze And "the Origin Of Glazes" Essay

WOW! Thanks for the reference Tyler. I got interested and went to Weiss's main page http://www.gustav-weiss.de  This guy is amazing! I also love the great display of his glaze painting and sculptor.

 

Spent about three hours reading his essays and looking at his art. This guy is a true ceramic philosopher not to mention a fine ceramic artist.


In Topic: Reduction Kiln- Too Early?

09 August 2014 - 02:38 PM

$300 is a good price but as mentioned, there are other costs to consider, especially if you have to pay someone to hook it up and build a shelter.. I have often wished that I could do reduction, since it opens up a lot of glaze possibilities that  I don't have now. If I could find a kiln for $300 I would jump at  it.
