U mean you put the subject in a jar, wrap it with an insulated aluminum-jacket and let it sun burn. Of course you cannot close the jar or it MAY explode. Depending upon the length of time u put it out in the sun + the strength of the sun; it may be cooked, burned or raw. It's very much like a DIY solar air heater or solar water heater: Just let the sun do the work. Make sure whatever chemical you put on the jar or "jacket" (if any) is edible. The sun will do the trick anyway

@LOOKlearnLAUGH Short answer is no. It is a canning jar, the lid is on a bit loose and is designed to release pressure anyway. There is no aluminum jacket, the insulation is just a plastic bag or an oven bag wrapped round the jar.. The reflector shields a lot of wind from the jar but its main job is to reflect the sunlight to it and concentrate it for a decent length of time. Supposed to be about 2 hours.

Hi Gaiatechnician,

It appears as though you used the rubber seal when you cooked with the canning jar. Have you ever had one of your canning jars explode? I just tried the experiment with a canning jar but I was reluctant to use the seal with the clamp as I cautioned that the pressure might shatter the glass if none of it(pressure) is allowed to escape. Great vids. and inspiring ideas.

[gaiatechnician]

I did not have the jar sealed (the lid was not tightly screwed down). I believe you can have them sealed but why risk it? The seal is part of the lid with my type and i just leave it loose. Thank you for comment

Thanks for showing us a new twist to solar cooking - in mason jars no less - great idea.

[gaiatechnician]

If you add a little molasses to the water, it darkens a lot and absorbs heat better.

[SororThothma]

Paint your jars flat black to increase heat absorption. You can apply a stripe of tape prior to applying the paint and then strip it off after the paint has dried so as to still have a window to view the interior of the jar with. High temperature paint works best.

I hope this helps.

Interesting video, I'm in the central part of Ontario, it's so cloudy lately. But I would like to try this when the sun's out. Thank you for posting!

if you add a pinch of salt and a pinch of sugar your veggies will retain the color.

Saw this on the internet 6 years ago. I use an old auto reflective shade I bought a Goodwill. Chicken Wing Adobo, Gumbo, and Minestrone Soup are favorites of students. Thanks for keeping simple.
