Hello, I need some advice here :)
I watched a video on youtube about baking polymer clay on light bulb (to get a sort of a '3D' look), but I have a few questions and I'd be glad if anyone can answer:
- is it safe to bake a light bulb in a domestic oven? (Nothing dangerous happened in the video, but I just want to make sure) Do I need to take some 'extra' precautions?
- is the clay going to stick to the bulb?

Thanks in advance :)

I've never had anything bad happen by baking light bulbs in the oven. I have made Christmas ornaments by covering burnt out light bulbs with polymer clay . If you are using the bulb to get a curve on your piece, then it should pop right off the bulb after baking. I've done that too, but the clay will get shiny spots during baking. You could always dust the bulb with baby powder or corn starch and then it won't stick at all. Good luck!

I cured these mini-bottles today in the oven. Never been a problem, although I do use an oven thermometer.
I made it back to etsy after a few days of studio time to "clay".

Instead of a light bulb, I use a round wooden ball that has a flat bottom. I bought it at Michael's. I think it is used for making doll heads. There are two sizes, so you can get two different degrees of curvature. I don't have any problems with baking or clay sticking to the wood.

Thanks for the answers everyone, I'll post the results when they're ready :P
Jan, I don't think these balls are available around here, so I'll try with bulbs until something better comes up.

Thank you for raising up this theme! I also have wondered about baking the light bulbs.. Hope to hear about the results soon!

I use a glass jar for curves, and a friend of mine uses a broken ceramic mug. They both work pretty well.

I've used a lightbulb to round out the shape of a piece. Turned out fine. Just make sure that the bulb is nestled in something that isn't going to roll. I put mine in cotton batting, the kind for stuffing pillows.

Sevdalina, I didn't look to see where you were located. Yeah I don't think Michael's crafts has made it to Bulgaria yet. Other wood options - looks for old round wood pieces that were used for finials on stair, or bed, posts. If you know a woodworker, have one made. I wish I knew one so I could have some made in different sizes to get different curvature.

I like the idea of using an old ceramic mug for making pieces where you need a gentle curve in one direction. It would work better than the paper form I made.
