HI Marie,
I would be glad to share with you what I know about the media, and also very interested to hear what you are working on.
I prefer not to get into the topic on the forum again tho, as it just sparks wars and sarcastic comments, my email is
dvport4@prtc.net
I have a bunch of info on it and some background info on ceramics and even the dreaded FIR. What are you working on? Just so you know the media was designed for a shower not immersion, but folks do it use successfully immersed.
