This shell is then hung upside down in a burnout furnace, where the shell not only dries but bakes the ciramic hard, and dewaxes.
I do believe that we are talking about different things here and the possibility of there being a difference in terminology between different English speaking countries may account for us talking at cross purposes, (no offence). - You have done a very good description of lost wax investment casting.
What I am discussing is different, it needs to be sorted and I will endeavour to find something which will explain what I'm trying to describe, - and don't think for one minute that I think I know best, just a misunderstanding you understand!
The 'Blawknox' process does sound similar I must admit - what did they call that process?
These are just a couple of sites where it explains it the way I knew it. (American spelling too.)
jkimberln has got it right in his post on the subject, (to my way of thinking).
