There is no convection in an electric furnace

It's been a little slow and I thought some may find this interesting.

Movement of heat through convection ends at around 1100 degrees F. At 1700 F, a cubic foot of air has only about one-tenth the number of molecules as at room temperature. This is why there is little airflow at high temperatures.

We had to call a serviceman to come out and try to fix my wife's convection cooktop in our new "forever home" ....He couldn't fix it, just simply didn't know what was wrong with it. Turns out ya gotta use stainless steel cookware
...I came close to buying a convection forge awhile back, would have been just the thing for spider legs!

Induction heating probably deserves its own thread but I'll tell you first hand induction forges are well worth the money. I'm blown away at the speed and the ability to localize heat. You can buy one of the import induction forges for way less then you would imagine. I'd also guess you have a water cooler from your tig. Anyway Bill Roberts bought one just for fireplace tools you should ask him about it.


I also bought into the induction cooktop craze and if I knew it was going to be so noisy I would have stayed with gas. As a matter of fact ours was so loud we yanked it and it now lives in the shop. Yours is probably of better quality with quieter cooling fans.


Anyway splurge a little Duck buy an induction furnace it's really perfect for some of your work. I know you'll love it.


Now how can we apply it to glass. I wonder if sic heats with induction. I'll try it and let you know in a bit.

her's is a Kitchenaid Convection Cooktop, doesn't make any noise at all but works only if you use stainless steel cookware, go fig'r.

I really would like to have an induction forge. It's fun to say induction out loud too.

Magnetic. Anything attracted to a magnet will work. Can be clad. So....certain stainless steels will not work on the cooktop. Big heavy lodge cast iron will work perfectly 😀. Copper will not work.

It's amazing how fast an induction cooktop will boil a pot of water for pasta.

Was watching a show where they melted gold in a table top induction unit. Amazing how fast it melted the gold just sitting on a table top.

Is anybody here using an induction coil as a pipe warmer?

Ok Sky, I see how I confused things. A convection oven cooks more evenly because a fan circulates the hot air, and if I read you that has some limits of around 1100f?

donno how I got caught up in the "Induction" thing

btw, hope Irma makes a U turn!!
