Log in now. We have some of them and also Corelleware. It is a big difference. I still nuke things on the plastic if it is just a mild warming, but for any major heating meat or boiling liquid I use the Corelleware or other microwave safe item. Those things get hot too, but from the hot food not from direct heating.

Post by earlyout » Mon Jul 31, pm Paper plates work quite well, they only get hot where the food is. And you don't have to clean them. Post by » Tue Aug 01, am climber wrote: I use corelle plates. Ten dollars? Post by Dendritic Tree » Tue Aug 01, am Just a caution - dishware marked "microwave safe" can still get super hot. I know from unfortunate personal experience. I agree with all the Corelle recommendations though,. DW and I bought a set of stoneware from Pottery Barn about ten years ago.

When first purchased, the plates and coffee cups did not get hot in the microwave. Now most of them get searing hot.

When I inspect them carefully I can see micro-cracks in the glaze, probably from years of use, dishwashing, microwaving, etc. My theory is that these cracks in the glass glaze allow the microwaves to penetrate to the fired clay plate and heat it up just like food.

If your dishes are old and have fine micro-cracks in them, it's time for replacements. I have tested this theory by using some pristine extra plates that I had bought, stored in the attic and never used till now and they don't get hot in the microwave.

Post by Tamales » Tue Aug 01, am Yep, the "microwave safe" label does not mean the plate or whatever won't get hot.

Some of them get very hot. I thought microwave safe had to do with leaching toxic chemicals but an online search shows the definition is unclear. It came with a manual which gave a method for testing whether a plate or cup was microwave safe, because there really wasn't a lot of microwave safe stuff out yet. Place the item to be tested in the microwave with a cup of water.

The water will heat up but the item being tested should remain cool. If it heats as well it is not microwave safe.

In every case the clay composition has to be so that at the 'maturing temperature' it begins to vitrify and the partial melting of some of its components provides the 'glue' to provide its strength.

Other chemical changes take place during firing. These include burning off all organic matter often found in many clays, the decomposition of carbonates, which are common ingredients of many glazes, and further crosslinking of metakaolinite to give a three-dimensional network with the elimination of water. This process does not go to completion up to earthenware temperatures,4,5 but at stoneware temperatures all water is gone.

It is difficult to believe that water is present in pots fired to earthenware temperatures, but easy to demonstrate: Take two cups, one earthenware and one stoneware, and put water in both. Put them into a microwave and run it at full power for minutes. The water in both should be hot; the handle of the earthenware cup will also be hot, while that of the stoneware cup will be cold.

Since microwave ovens heat water by causing water molecules to move faster, the hot handle on the earthenware cup indicates the presence of free, mobile water molecules. At stoneware temperatures, the metakaolinite undergoes transformation into mullite 3Al2 O3.

These two structural changes account for the much greater hardness and strength of stoneware over earthenware.

The continuous execution of a sound strategy gives you the benefit of the strategy.

That's what it's all about. Post by retiredjg » Wed Aug 02, pm Good Listener wrote: It is chicken already cooked that is then being heated. I was in Bed Bath and Beyond and hanging in the kitchen area were set of 4 microwave plates that "stay cool in the microwaves ".

There have been no food safety concerns reported when it comes to heating food without cover but it does have some disadvantages. These include, Dried up food with the texture and taste of the food destroyed. Uneven heating of food. Put your first bowl in the microwave, then put a coffee mug upside down next to it. Next, place your second bowl on top of the coffee mug and voila—a multi-level microwaving system.
