Anybody used one of these to preheat rods?
My daughter is a hair stylist and I saw this thingy at her beauty school. A light bulb went on in my head. One of those aha moments. It is a heater (460 F) for metal combs and curling irons used to process African American hair. If you google "hot comb heater" you can find it. They cost about $30-$40. I did modify the little wire extension to accomodate glass rod lengths and it works like a charm and doesn't take up much space on my bench. I can also preheat murrini on the flat top. Just thought I would show you. Maybe someone has already figured this out but it was new to me.

There are a few people that use these, but not many.
I've seen it here before. You might want to do a search. There were some great suggestions on how to keep the glass rods from sticking to the inside of the rod warmer.

I use a small George Forman grill that a buddy picked up at a yard sale for me for 5 bucks. It works swell.

sticking rods
Yes Deb! I avoid the sticking rods by not putting them inside when molten! (Of course, this has never happened to me, I am just imagining.......)

George Forman!
Very cool idea! I think you need to write to George and tell him the new function that his machine performs!

Wow! Those look great. I have been using one of the little hot plates you set your coffee on to stay hot.

I was looking at the links Ro posted and the top temp is 460 degrees Celcius, not Fahreneheit - 460 C is 860 Fahrenheit.

I've used one of these for a long time... I depend on it. (Tho I can understand why you sold it, Ro!!!) It does bend my rods... I've been meaning to put a dimmer on it for a while.

I've been using one for about 2 years now. Works great and really does reduce the popping with shocky glass. I put a piece of hardware cloth on the bottom to keep the rods off the ceramic - they get hot but don't bend or stick.

like a kiln shelf, you mean? They're not exactly kiln brick -- kind of a cross between firebrick and ceramic. I'm not sure you'll find one as narrow as you need for one of the rod warmers, but maybe you can cut one in half -- know anybody with a tile saw? (an unglazed tile ought to work inside the warmer, by the way.)

I use one of these too. I picked mine up on ebay used. They do pop up every once in awhile. I would love to see a better picture of how you set your rods up though. I have something in front of mine, but it could use some improvements.
My rods have stuck to the inside if I put them in while they are too hot, but it doesn't seem to hurt the ceramic insides. I keep trying to find a piece of hardware cloth to put in mine, but haven't stumbled on any. All the hardware stores carry is galvanized stuff.

You can also use a piece cut from a metal gutter guard - usually about $1 at HD or other BORG stores. It's easy to cut and shape to fit.

Great idea! Too bad I don't have any gutters to steal from my own house.

I've been using one for a few years, and LOVE it. I dont know what I'd do without it. Two more advantages, some of the rods with the air bubble running down the center, preheating them in here stops them from exploding. (You do need to let it reheat b4 you get to the cold part)
and it will strike many colors so you can see which stringers are which
I've been tempted to put beads in it that didn't strike properly, but haven't thought about it at the right time.
I dont worry so much about it sticking, I dont put the glass in molten, but if it does stick, it comes off in a few minutes. The bottom of mine is covered with bits of glass.
and it's soooo hot, it will heat a rod REALLY fast. Dont need to plan ahead. (haven't learned how to do that yet....
