What to look for when buying a Kiln

What cone do you plan to fire to? If you'll be doing cone 6 work, elements in a cone 8 kiln won't last as long as a cone 10 kiln. As for what's a deal breaker, that depends on what level of repair work you're comfortable doing. For some, rewiring the whole control box is not a deal breaker, for others it is. In general, though, you want the wall bricks, floor, and lid to be in good condition. The electrical system can all be easily replaced. If it needs new elements, though, that'll cost you about $350, more if you pay someone to install them. If the wiring looks old and corroded, or the wires aren't soft and flexible any more, they'll need to be replaced. If the plug is corroded, you'll need a new power cord ($100). If it's got the old interbox plugs, you may need to upgrade that as well.

I’d love to be able to fire to cone 8, not sure how much use this kiln has had all ready. As far as longevity I’m just starting out and learning about kilns so even if I had something that’ll only last me a couple years I’d be happy with that. I’ll be sure to ask and check the things you mentioned. Still figuring out what would be best for me. Thank you!

If you fire a kiln to its max, then it won't reach temp once the elements wear even a little bit. for best element life, you want to fire 3-4 cones below the max rating of the kiln.

If you have a multi-meter, you can check the element resistance and compare it to new elements to see if they're worn.
