[TheForge] Mineral Wool

[Jerry Frost]

This topic has been coming up for as long as I've been 
on the list and for the reasons you give it's virtually 
imossible to make a meaningful determination.

There is however one meaningful test a person can do 
and that's measure their forge before and after 
applying an IR reflective coating. Unfortunately that's 
only going to tell you what happened in one furnace. 
Maybe if enough people did it and recorded the results 
in a central file we could develop a range of 
expectations.

Till then we have only the manufacturers data and 
anecdotal evidence. The anecdotal is impressive enough 
to make using an IR reflector regardless of furnace 
liner type a no brainer though.

If it ain't forged
it ain't real.
Wrought iron is.
