Thank you for the great education

[@WashingtonStreetStudios]

And thank you for watching!

From India. What a lecture! So much information with crystal clear clarity and with foundation of scientific explanations. It gets embedded in your knowledge bank and can never forget. Thank you so much.

What a great explanation for why someone should learn the technical aspects of ceramics... so creativity isn’t hindered! That’s so good. I love this channel and although I’m new to this, I’m learning so much so fast 🙏

Jake, that statement hit me as well! Phil was my first instructor in pottery about 15 years ago and I'm still learning from him today! Thanks for the comment and tell your friends and fellow potters.

i realize I'm kinda randomly asking but does anyone know of a good website to stream new tv shows online?

@Van Brecken i dunno I use Flixportal. Just google after it:) -imran

Do you all have show notes or transcripts for this series on electric kilns? I didn’t see them on your website.

[@WashingtonStreetStudios]

Sorry no.

I'm confused about the topic of ageing elements. If the resistance is increasing, why is less heat produced? Low resistance wiring does not produce as much heat as high resistance wiring, so how does an ageing wire with increased resistance produce less heat. It seems to be contradictory.

[@WashingtonStreetStudios]

The first time you fire your kiln, you create a layer of oxidation on the elements. You want the kiln empty so you don't have contaminants in the oxidation layer. This helps by providing a barrier to further oxidation of the elements. Every time you fire your kiln the elements expand when heated and contract when cooled. This results in tension between the the oxide layer and the base metal because they expand at slightly different rates. Cracks are created in the oxidation layer which expose the base metal, which then oxidizes, elongates the element and the diameter of the base metal core is reduced. As the base metal core gets smaller and smaller, the resistance increases and the element runs hotter, however the reduced diameter of the core metal in the element causes an even greater reduction in the power potential. The net result is less radiant heat in the kiln and less heat transferred to the pottery stack. I hope this helps, Thanks for the great question.

[@gbennett58]

@@WashingtonStreetStudios That helps. The reduced diameter limits the amount of current passing through the wire. Thanks.

Great answer, thanks!
