So this is my first time working with fimo after seeing it a couple places. I am currently working on a conversion for a contest over at Worldeaters.net and am using some FIMO on my base to make a plinth type of thing. If I have the FIMO on a base along with some plasticard, superglue, and greenstuff.

What I am wondering is if I can put everything, including the base in the oven at 230 degree F without everything melting? or do I need to bake the FIMO seperate from everything else?

The greenstuff should be fine. The superglue and plasticard are a bit more iffy.

I've seen it mentioned that superglue can explode under high temperatures (no idea how high it needs, though) and I would guess that plasticard, being a pretty soft plastic, would havea fairly low melting point.

I'd try it on a scrap piece first.

Jeez Insaniak your making me go insane.

I got an email saying that there was a post here, with the message. Then you had editted it once and I thought i had double posted and began looking for my second post. then when I came back you message had changed, which once again made me think that I had double posted. And again i just about started to look again for my other post when I noticed the edits...

So did i double post, if I did I am sorry, I did not mean too. other than that I am halfway through my first test and it seems that glue and plasticard are pretty good in an oven (at least on a small scale) but bases however do seem to warp and melt pretty badly...

more info to come when I get it.

It will smell really bad at least. I'd do it seperate from the rest of the piece just to be on the safe side.

So after a closer inspections here's the deal with heat:

Base: Extreme Warping in all three dimensions. Completely ruined

Plasticard: I used small pieces although there was still some definite warping. i think it would be more the larger the piece.

Superglue: Seemed relatively good. Although with nothing that you can glue together it seems relatively useless...

Plasticard melts at 160 C, Gas mark 3. thats the temp I use for vacuforming

I wish I had seen this thread earlier...I would have pointed you to my experience:

Sam as you...base warped/

Cardboard does well in the oven. I used that when I made my sandbags out of FIMO, and will do again when I do the next lot.

I was expecting it to spontaneously burst into flames but it held good.

@General Lee - The plasticard didn't melt, but it still gets hot enough to warp it pretty bad at 230 F

@zeronyne - Yes, I had a sneeky suspicion that the base would not make it through the heat, but I had some extra's and figured i would try it.

@tek - unfortunately, cordboard does not really work for what I am trying to do. I wanted to make the whole base and then sculpt it, and bake it. Now i will have to use some vaseline to make the FIMO not stick to the other parts and bake it seperately and then glue it onto the base. Also, i beleive that paper spontaneuosly combusts at just over 800 degrees fahrenhiet (450 degrees celsius) so there really shouldnt be too much of a worry about cardboard igniting itself in an oven.

I agree. I would just use the FIMO / sculpey for the basic structure and from that point, just use plasticard and gs for the finer workings. You can also separate your plan into parts - working on the ovenables on one part and the non-ovenables on another.

It's half that. 450 degrees Farenheit. Ray Bradbury's Farenheit 451 (I recommend everyone to read this!) is named thusly.

That is what I origionally thought as well, however I couldnt remember the specific number and so i did some research. This is what wikipedia says:

"The number "451" refers to the temperature at which book paper auto-ignites. Although sources contemporary with the novel's writing gave the temperature as 450 °C (842 °F), Bradbury apparently thought "Fahrenheit" made for a better title"

Lol... sorry. The double post reference you saw was to myself. My reply posted twice. I went to edit the second one out, forgetting that Dakka's system does that automatically anyway... so when I finished the edit, all that was left was the post saying that I had double posted. Which I then edited back to my original reply.

Apologies for any confusion...
