  1. Most of the paint your own pottery places around here are just names like "five line pottery" and stuff like that. They do really well, but they also are potters and do shows, so they're constantly out there advertising their paint your own pottery business as well. I see their offers on Groupon all the time so I bet that brings in a lot of customers too. Just a thought
  2. Well it depends. Since you're controlling input voltage, and your elements are wired in series, each is receiving a fraction of total available power, right? So if you remove half of the elements, they will receive twice as much power at the same input, creating more heat. The problem comes when you have reached the maximum input (120v @20 amps?) And it's cut in 4. So yes there's more points of heating, it will be more evenly heated, but with each element putting out a quarter of the heat. Now if you turn that down to two elements, you stop running into that false temperature ceiling because those two elements are able to run at a higher wattage. But the heating won't be as even. At least that's the way I see your problem. You're thinking only of total wattage and not wattage per element. I could be entirely wrong because I'm not an electrician or engineer, and really have almost zero experience in either, but just from a pure math problem perspective I see an oversight
  3. Yeah. Any clay company should be able to do this for you. My supplier does custom mixes, but there are minimums. Also prepare for sticker shock, you'll probably pay their wet pugged ton rate, not the rate of buying the raw materials. You can maybe ask around at your local suppliers to see if you can work out a deal, maybe rent a mixer and pugmill and do the work yourself. You never know until you ask!
  4. Spray the board with hydrogen peroxide to kill the spores that are all over it. Impressive that it's able to stain through the glaze fire, the mold must be concentrating metals (which is common in fungi). I'd say killing the source is the only way to really control it, but mold spores are pervasive so control is about as good as you'll get. Can you flip them every day so that the mold doesn't have that moist stagnant surface to grow into?
  5. You'll need to make sure the wiring and circuit can handle the amperage it's going to draw. You should be able to find a nameplate on it with the specifications of the kiln. After that you should be able to type in "how to fire a manual kiln with kilnsitter" in YouTube and get a bunch of videos showing the process.
  6. Amazing! Nice work and hope everything goes well with your new one! Happy firing
  7. Whoops! That's what I meant to type hah
  8. .25 ohm 10% 22 watt ceramic cement resistor
  9. I'm no anthropologist, but if YouTube videos of Canadian engineers is any indication then yes.
  10. They're somewhat common outside of the US. I've seen some Chinese ones that use silicon carbide rod elements, and seen Italian ones that use coils. I think they probably just end up replacing the wire elements more often and chalk it up to operating costs.
  11. The technical term is Sizzle Sauce. It's only happy juice if you're speaking from an appliances perspective. Angry pixies if you're Canadian
  12. Yeah you.want to fire the hotter one first, and then fire the colder one. I think gold is cone 018 and mop is cone 021? Something like that anyway.
  13. I think that's molten metal from receiving 50 amps of happy juice
  14. Could also try adding thickness to the liner glaze to make it more even with the outside. Might as well if you're gonna be doing some freezer->boiling tests
