Absolutely agree with this. I have complete piece of mind about using these as my own little experiments show that these wicks are not decomposing and do not change at all under extreme temps. However, it is in everybody's interest that full disclosure on materials is forthcoming. In that way, people can make an informed choice about whether they want to try them out or not. What is a good strategy to pursue do you think? Should we put some pressure on suppliers to find out from the makers? I wonder if Scuba Dan has gone down that road already? Anyone have a friend in China that could make some inquiries (I think that is where most of these materials are being made)? One possible snag however, verbal descriptions and assurances are merely anecdotal and if there is no current requirement to do so, is any company going to put on paper detailed information on materials if there is no legal or monetary reason for it?
Just on a side note, I was looking at images of porous corals today. Some of these have very fine porous structures. How would this be for some experiments? Talk about a no mystery material, it is basically pure calcium carbonate. Should keep all the chemo-phobics happy. Great for healthy teeth and bones
Here is a core sample:
This one is a little too porous but other varieties have much finer structures. Maybe some potential here.
