epoxy resin sludge in bottom of container

in the bottom of two of my containers of epoxy resin, the big container, there has developed a fairly sizable mass of crystaline sort of sludge. I suspect that it is from cold. when I wam the continer in the sun is largely liquifies.

 

wondereing if anyone else has experienced this and is a little warmth or heat all that is needed to get back in business? any permanent issues?

 

there are some internet postings elsewhere suggesting using a microwave but my gut says not to. Any thoughts?

   David,

It's harmless. It's the result of the resin getting below freezing. Just warm it up by putting the bottle into hot water for a while. The crystals will disappear and your resin will be as good as new.

The microwave will work, but it's not as safe as the water bath. Besides the possible explosion, there will certainly be contamination. You'll never be able to use the microwave for food again.

Be safe,

Laszlo
