Try calibrating your thermometer.  Boil some water on the stove, and when it's briskly boiling, put your thermometer in and see if it reads 212 F.  (If you live at very high altitude, the water will boil at a slightly lower temperature, so you'd need to look that up.)  If it doesn't, you can still use it, but you need to make a temperature adjustment.  For instance, if your thermometer reads 200 F in boiling water, then you know the actual oven temperature is 12 degrees higher than your thermometer says, so you'd adjust your oven temperature until the thermometer reads 263 F, and then you'd know the actual temperature in the oven is 263 + 12 = 275 F.

I also cover my clay with a foil tent, bake on a pizza stone to provide a more even temperature, and preheat the oven to avoid temperature spikes.  HTH - Beth

Good idea, Beth. I feel a little uncertain about putting an over thermometer in boiling water. They don't appear to be sealed. Have you done it?

I do all those things to account for spikes. The real issue is not being about to find out what the temperature really is, so if it's safe to test the thermometer, I'll do it. I will say that they're both extremely slow to respond to changes in temperature, so it could be a grueling activity!

I use a probe-type thermometer, made to be inserted in meat, so I know it's water-tight.  But if you have one of those sits-on-the-shelf types, I'm not sure if that would be.

i spent a small fortune for a Breville brand counter top sized convection oven that holds a constant steady temp. https://duckduckgo.com/?q=convection+oven&ia=products&iai=B00XBOXVIAhttp%3A%2F%2Fecx.images-amazon.com%2Fimages%2FI%2F41d-dfKE33L.jpghttp%3A%2F%2Fecx.images-amazon.com%2Fimages%2FI%2F41d-dfKE33L._SL160_.jpg

there wasn't a single one for less money that ever worked more than twice before it went wonky.
