Roger on'nat, TBilly, thank You Sir. Cooking in an actual pot has crossed my mind a time or 2. Reading Your post here, that's my next move.
In much thinking, and wanting to try something before opening the little Presto, I planned to "set" the Pyrex into the top of the Presto, then came the Kamikaze part that I'm trying to avoid posting. Once I made my decision that this would add too much negative possibility, I decided on what seems to be a more finely-adjustable Electric Single Burner and a 1 quart thick pot, $45 total, and I'll try to return the Presto unopened.
If this works right at all, I'll salvage what I can from the 2 microwaves and bring the rest to the scrap area of the dump...which will open up my workbench quite a bit...and that's never a bad thing.
Thank You, Jason and Family, for Your awesome Company, Products and Service. I'll always favor CCM, hands down...no matter what anyone says...yep, I'm biased.
