Knife kiln?

I seen this at the thrift store today, it is filled with fire brick, and has a heating element on the top side, also on the right side is an opening where what looks like would fit a longer item like a knife, it has a small fire brick that fits over the opening.

Would this work for heat treating? I am trying to figure out if it's worth $10 bucks to try it out any thoughts?

My first thought was a ceramic kiln, but there is only about 2" clearance inside. Its just not very deep, I just can't figure out what it would be used for other than a knife, especially with the opening on the side.

I would say probably not. It doesn't appear to have any model info to tell how hot it can get. Heat treating requires some pretty high temps. Without seeing the inside it is really hard to tell. Also the clearance might be an issue. Maybe good for parts?????
 
Looking at the (rather poor) photos, that is some sort of low output heater. It won't be of any use for knives or knifemaking. It may have been a table-top heater for a glass bead maker or some older piece of medical or laboratory equipment. FWIW, the company name does not come up in any search.
 
Yes, after googling "jewelry kiln" I found several good matches.

Thanks for the info...
 
It could work if it gets to 1500 F. It could also work for case hardening of small parts if you have a need.
 
That is what I was referring to. They are used a lot by the enamel and glass bead folks. They are low power and unregulated ( they have no controls). It is useless for any knife work.

For $10 it is a good buy, but you would have to add a PID control and make a fire brick door to use it. And even then it would only do carbon steel folder blades.
