Hi,
I have built an oven with wood and house fiberglas
insulation, foam and light bulbs.
Its a 30" X 12" X12" oven,
uses four 100 watt light bulbs and I can get
temperature up to about 400 F. Balsa starts turning
colors at about 375 F and becomes pretty brittle.
Temperatures over 425F is were I find that balsa
starts charring/burning. I try to cook my parts at
300 F.
My sister had many years ago an Easy bake oven that
would cook cakes and it used a 100 watt light bulb.
