Extra 240v circuits - what to do?

In my utility room there is an electrical box with a blank cover.

Inside are three conductors - a red, black and white. All three conductors looks like either #10 or #12. The wires are capped with wire nuts not connected to anything.

The red goes back to a 30A breaker. The black goes to another 30A breaker. The panel label for these two circuits says "Kiln". I guess there used to be a kiln may be for pottery or clay?

I am wondering if I could use these two circuits for something else? Besides having extra dryer?

I would put in a 2-pole 20A breaker and install 2 gfci's in the box. Now you have 2 20A circuts to plug in whatever.

Is there a ground wire or metal conduit between the box and the breaker panel?

There is a EMT conduit between the box and the panel. There is also a green ground wire screwed into the metal box.

You can repurpose that circuit. You would need to check if GFI protection is required for that area. You may also need to pigtail a smaller wire onto each to allow the conductor to fit the devices. A breaker change may be required.

General purpose circuits are limited to a 20 amp max.

If you reduce the breaker size to 20a for a multi-wire 120v circuit be sure you use a 2 pole breaker not two single pole breakers as you seem to indicate you now have.
