I've used oven drying for Magic Sculpt, but not for Duro. I don't know if will behave the same. For Magic Sculpt I have put in a 150-200f oven and keep a close eye on it. Lately, I have been using my desk lamp to aid in setting putty. Just place the object under it. I also have a small crock pot that was intended for drying oils, it works for putty as well. What ever you try keep a close watch on it or it could blister.

It should be fine, I usually only set the oven to about 50/70 so that you heat it and not cook it, usually takes about20/30 minutes in which its time to put the next piece in! you can only try so mix up a blob and put it in
You can also place it close to a lightbulb in Mike Blank style.
I believe the curing time of any epoxy putty is reduced by heating it.
O,.. and if you are going to use an oven, be aware that stormtrooper is talking Celsius and John Long Fahrenheit.
Cº=5/9(ºF-32) So 150-200ºF would be about 65-95Cº here in the old world. Otherwise tou might incinerated your masterpiece!
I'm not trying to be smart here, I just read it.

Heating any 2 part putty speeds up the reaction time and brings the catalyst - resin cure to completion much faster.
FYI - roughly the same process is used in the fiberglass industry, especially for sheet or formed sections of fiberglass. 150 - 200 W bulbs are used to speed up cure of formed or molded sections. Sometimes other kinds of heaters also. Aircraft radomes and various other sections are frequently made of a manufactured metal honeycomb with lay-up fiberglass as the exterior surface. Most USAF maintenance units have fiberglass shops where these are built or repaired.
Personally I use a small 'Crockpot' - an old one that my wife was preparing to put in a rummage sale. Works well on the low setting only. 10 - 15 minutes and the piece is fully cured. Don't use high!!! It's too hot - can cause bubbles in the putty and resin melting. Speaking from personal experience!! :angry:
All the best,

I've sped up the curing time of Aves epoxy using a desk lamp. You can position the lamp close or a short distance away. It's not too hot an I've found a half hour to an hour cures the piece enough to carve or sand into. Though it does not get the piece too hot you still want to keep an eye on it just to be safe.~Gary
