Well, my nomex is finally starting to fail. It lasted much longer than the felt gaskets, though. I was thinking about a Rutland, but was told by the local egg dealer they contacted the maker of Rutland and were told emphatically that they were not meant for use in food preparation. Are there some sort of funky materials used to make either the gasket itself or the adhesive? Anyone ever seen an MSDS sheet on them. Even placing it on the bottom as to not have it hovering over the food when the lid's opened. I was also thinking about just going gasket-less and buying aluminum tape to seal the outside for low and slows. Any thoughts would be appreciated.
