Shawn, I'm sure others here are smarter than I on this. But, if it's not high temp paint I just put them in a sunny window once they are dry enough to handle.

Once they are to the point that I can't smell fresh paint I figure they are pretty much cured.

I do regular paints in a small convection oven at 200-250F for an hour. Let cool for another hour before touching the fount, as the heat leaves the paint soft until it cools.

I'm the king of overkill when I paint. When I paint a fount, i always top off with two coats of high heat clear. Then bake for 30 minutes at 200f. Then 30 minutes times two at 400f. Letting it completely cool between. I bought a toaster oven at Goodwill just for this purpose.

I have a George Forman rotisserie toaster oven found at a secondhand store for this purpose.

I also use around 200 deg. F and cook it for 45 mins. That's with the base coat and clear coat both.

I tend to follow directions on the can. But IMHE any paint is tougher when baked some even if it says nothign on can about baking it. If no instructions, I go 250 or so for 20 minutes, not very exact about it.

Toaster ovens are common in thrift stores around here. I got a very nice one for $7. I bake founts at 200 F for 1/2 to 1 hour. We have one of those natural gas fireplaces, with the fake logs, in our living room. During the winter, founts hang over that fireplace sometimes for days.

Shawn,
I picked up a nice toaster oven at the little thrift store on the right side on Oracle before Red Lobster. Sharing my honey hole so don't tell anyone. There is usually a woman mannequin by the driveway

I will start looking for a toaster oven. In the past, I have used a gas bbq grill with mixed results. The temperature has to be monitored constantly.
Thanks,

I baked a newly painted fount in the kitchen oven ONCE. I was then banned from ever doing this again by my better half.

So I bought a big toaster oven and bake at 225 for 20- 25 min. For frames or other parts painted with VHT Flameproof paint I cure the paint at 250 for 30 min, cool to room temp, the 450 for 30 min.

You do it when the better half isn't home. Then pretend you don't know what that smell is.

It was her idea not mine!
I was shocked when she suggested that I bake it in "her" oven.

Do not be surprised if there's snag to that.
I'm expecting the following to happen soon:-
1. She would no longer be baking anything for you in that oven.
2. She's expecting you to buy her a new one.

Oven to 250, pop it in and turn off the oven. A few hours later I take it out. Seems to work well for an impatient person like me.

I don't have any argument with what others have posted here, but I've found that for ordinary rattle can paints 170F for 30 minutes is enough. I turn the oven off and let it cool with the door closed. For high temp paints I follow the directions on the can, but rarely do the 600f cycle.

After getting in trouble while doing the final 600f stage, I tend to agree with Reese.

What kind/age of fount is it? If its brass they mostly use a soft solder which doesn't withstand much heat at all before reflowing. Even the steel ones of the 30's can't stand much past 300f, so keep that in mind when curing.
The later steel ones use a copper braze that, according to Coleman's info, is set at 2000 degrees.

I melted the solder seam out of the tank on my Monkey Wards "The lakeside" by curing VHT paint at 400F. There's really no need to use high-temp paints on a fount, but the way the "sled" of this stove is put together, the burner base and tank are connected. I was able to re-solder the tank.

I agree with Timm that you don't really need to oven-cure the paint on a fount. Ain't too good for the soldered joints.
If you really want a finish with a harder surface, there is an option of using the 2-pack, room-temperature curing epoxy paints. They'll cure chemically into a tough, solvent-resistant finish. Some of the solvent-free types are about as resistant as Caswells tank repair coatings. Colors can be customized too.
These are a lot more fuel/chemical resistant than the general air-drying paints. Sometimes, they're available in rattle cans from shops that offer pre-mixed paints, but you'd need to use them up before they cure inside cans.
The usual application means for these paints are of course, either compressed air-assisted or high pressure airless sprays.
They are more often used in industrial plants and marine than domestic.
