Bowl holders
 

What type of batting should be used when making the microwable bowl holders?

only 100% cotton, no scrim, etc.

There is a batting called "Warm and Plush" which replaced the "Warm Tater". It is designed to go in the microwave.

I use a product called Wrap & Zap by Pellon.

The Warm Company does make Warm and Plush, but it is not for the microwave. In fact on their web site they say that they do not recommend that any batting products be used in the microwave. Any of them can catch fire if they reach the right temperature. This is the statement from their web site:

The Warm Company does not recommend cotton batting, polyester batting or blended batting for microwave use. Cotton batting, cotton fabric and cotton threads are flammable. Patterns recommending the use of Warm & Natural, Warm & White or Warm & Plush for microwave use are doing so without the consent of The Warm Company.

Wrap and Zap....I get it at Walmart,

i tell people to only nuke for aminute. ck, then put in again.

I made several for Christmas gifts and use wrap and zap.

I use Wrap and Zap. I had read somewhere not to nuke longer than 3 minutes. If it has to be longer, take it out of the microwave and turn the cozy to the other side and then nuke.

When I made one for my daughter I told her it can be used in the microwave but no longer than 1.5 minutes that it can catch fire. So what she does is use hot pads to remove the food from the microwave and then puts it into the cloth bowl.
