I know many out there don't care about gaskets, so I have some interesting info for those that do. A few months ago someone posted about some Aramid gasket material (generic nomex). They seemed to have good results. Hopefully that person will see this and chime in with how it's holding up. I placed an order and received it today. I decided to do a flame test, and held the same size of nomex and aramid in front of my weed burner on a low flame for thirty seconds each. Neither held up well at all, but the nomex looked somewhat like a gasket, the aramid shriveled pretty fast and had noticeable shrinking. This may be somewhat unfair since the aramid did not go through a shrink cycle in the dryer for 30 minutes like the nomex did. Anyway, here is the pic of the results (hope my iPhone pic and upload worked... ):
I will still give it a go on one of my eggs to see what happens, but I thought it was interesting and would pass it on to those considering this material.
