Can anyone give me an oven temp and such to do this? I've had some fondant pieces drying on kitchen countertop all week. I need to attach them tonight (handle and spout for teapot cake) but want them completely dry first.

I would put the oven on the lowest setting and put you items in there with the oven OPEN. You are really not suppose to put them in there with it on but, with the light bulb on instead which apparently is hot enough. But, I think if you put it on with it open is should be okay. I have heard of a frequent fellow CCer doing it but, I can't remember who! LOL

What a great idea! I've never thought of this! Ya learn something new everyday!

I have even done it with just the oven light on, and a rack at the highest level overnight. It may sound silly, but it gets pretty warm in there, even with just that, and isn't too harsh for the fondant.
HTH.

Oven light works great. Especially if you've added some gum trag or other gum to the fondant. Dries very quickly.

I had put some things in mine to dry a few months ago and the got so soft. I took the oven temp yesterday while drying a cast iron abelskeever pan and it was 100 deg F I was surprised it was so warm!!

I would recommend leaving the door open some too!

This is very interesting.The fondant won't melt in the heat??

as soon as I realized how soft mine were getting I took them out! But we aren't humid really (46%) so it was better under the fan on a cooling rack.

I do this all the time - oven on lowest (which is 120 for me) with the door open. Alternatively you can get a heat lamp on them.

My oven doesn't have a light.. should I heat to 150, turn off and then put fondant inside?

I have dried fondant pieces as Nicholas Lodge and Scott woolley says to do . You put them in a 150 degree oven , door shut for couple of hours. Mine dried great. hth
 

I have never had luck drying in the oven, it always melts.  So I suggest you watch it VERY closely to make sure it doesn't melt.  It is a real heart break when you have spent so much time working on something just to have to redo it.

I dry in the oven all the time, since I am a last minute, panic baker! I turn my oven to 170, the lowest setting, and let it heat for about 5 minutes, then put my piece in there on foil or waxed paper, then close the door and turn the oven off. I set a kitchen timer for a half hour, then check it, or turn it, or both. I melted some gum paste tiaras for twins once, though. I left the oven on for about 20 minutes, then turned it off, and came back about 2 hours later. and they were slid off the cans they were being formed on, but they were HARD! lol. I had to remake, last minute with tinted, piped candy melts! 

I am assuming that this only works this commercial fondant and not homemade MMF because the heat will melt the marshmallow? I have to make the sides to a wine box for a cake due Sunday (it is Thurs) and I just made the MMF today. Hoping to roll out and cut the panels tomorrow. Two days is not nearly enough time to dry MMF I don't think. Debating kneading in some dark brown gumpaste to make my fondant look more like wood. Can I swirl gumpaste with fondant, so that it has a swirled/grain look versus kneading it in completely?

Thanks!

I do this a lot too. I prefer leaving the light on. When I turn my oven to lowest temp. (170) and get it warm about 2 minutes, my fondant is a little bumpy. The light works better for me. You just have to leave the fondant in the oven longer.
