@jsbarretto I mean you have a high-temperature probe already, go build a PID-controlled fan :P  Over the week I made another mug. Much better formed. I fired it today and the results are quite pretty. Unfortunately I had very little charcoal left and I couldn't fire it for more than about 45 minutes, which is nowhere near long enough. It's since broken :( Also, not nearly enough glazing. Lessons have been learned, however! One of those lessons is to buy a better quality thermocouple that won't melt 350 °C below its rated temperature.  @Workshopshed Indeed, and the more air you can throw at it, the cleaner it burns: there was almost no (visible) smoke coming off the thing at all! |
I completely forgot to post this. Last week I made a mug and fired it.
Results:
- Temperature got up to 1,400 °C, higher than the melting point of iron. Far too hot!
- Using a fan to force air into the bottom is unreasonably effective
- I did a very stupid and wrapped the pottery in foil beforehand (to avoid scorching). Predictably, the foil melted and infused into the pottery. Results are not pretty.
