Thanks for all of the information and tips. It seems like there are many different ratios used and that they all yield a quality finish if the metal is prepared correctly. I have still not made or assembled the tank setup yet. I was initially going to use something like a pot to just blue small parts but am now thinking of just a standard 40in long tank so I can blue rifle barrels etc. Whenever I made my pipe burners for the rust bluing tanks I have I made a few extra for rinse tanks etc. and may have to do some work on them to increase the amount of heat they produce to raise the temp high enough. Thanks, Hereford
