Denmark Borosilicate Glass Cookwear
Recently bought at Sams Club in Mentor,OH a set of "pyrex looking storage: bake, serve, freeze, store items. Has anyone used these items?.
I was told to limit my exposure to reheating my food in the microwave using the plastic Rubbermaid like containers.
Don't know about the glass you bought but I have something like these glass storage containers and I microwave in them all the time. I loosen the lids. http://www.bedbathandbeyond.com/product.asp?SKU=17057456&RN=204&
I also have this borosilicate tea kettle that is up to direct contact with furious flames. http://www.flickr.com/photos/75667634@N00/3218560272/ Here it is in action. http://www.flickr.com/photos/75667634... My son even let it boil itself dry and we let it cool slowly and it was fine.
Hope you have such good results!
