hello all at the ngc forums. i'm glad to be able to post questions and read and learn something by visiting here, i appreciate the opportunity.

 

my questions. are the slabs sealed air tight? and if not is it not possible? do we not have the proper technology? and if the answer is 'no' is anyone working on this very important subject? thank you very much for your responses.
