9.5" Glass Plates
We found the 9.5" glass plates that we've been looking for at a thrift shop. They were 3 for less than $4.00. We painted one of them black on the back and baked it in the conventional oven for about half an hour @ about 250 F to cure the paint. We will use it for solar cooking bacon.
We will use the other 2 clear glass plates as lids.
To the right you can see one of the 8 nesting black bowls inside the trifle bowl covered with one of the clear glass plates.

8-piece Set of Black Bowls
While browsing through the clearance shelf of a local store one day, we spotted a box of Gibson 8-piece set of black bowls. http://www.gibsonusa.com/
They’re made from stoneware and are actually safe for the oven, dishwasher, and microwave. We, of course, didn't pass up the chance to buy them. We did a little research online when we got home and found out that the set is actually called a nesting bowl because they nest neatly inside one another.
We were disappointed to find out though that they have been discontinued. That's too bad because they’re just perfect for solar cooking. The smallest bowl was just right for our mini solar oven. Here are pictures of an egg we've successfully solar cooked in it. It was mostly sunny & 86 °F. The egg was completely cooked in 1 hour & 15 minutes.
Here are pictures that show how hot the 8 1/4 " bowl got. It reached 300°F after 2 hours. The test was done after 12 p.m., 83°F, with continuous sunshine.

Update on Homemade Solar Box Cooker
Our solar box cooker reached 250° F! It was mostly sunny & 86° F outside.Homemade Solar Box Cooker Temperature Test 3
After making some improvements on our solar box cooker, we tested it again to see if they made a difference.
It was partly cloudy, 88 F. Our goal was to reach 220 F.
We were surprised to see it reach 225 F! Not bad for recycled packaging.
