True, however Aide knows the best shallow mining locations for the 
appropriate coal and minerals, the ways one extracts, and building a 
bessemer factory oddly enough isn't difficult, the trick was discovering 
the process. Blowers are easy [blade turbines don't have to be more than 
a cast wheel for pushing air, and rotating is a matter of gears and 
gearing, which do need to be made out of something a bit better than 
plain cast iron, though a basic steel would work for the early smaller 
scale versions.] Refractory materials - the alumina and silica tend to 
be mined rather than 'cooked' in a lab for the earlier versions - fire 
brick isn't rocket science, we have had firebrick since the 600s - made 
with mined rather than lab created materia. [I actually have a stack of 
firebrick for an oven building project - much coarser than the firebrick 
material shelves for my kiln.] Though thinking about it, a Dragon kiln 
can generate some impressive temperatures over a fair period of time. 
And I might point out that fire clay is generally found as the 
underlayment for coal, the best source of shallow mine coal being the 
British Islands ....*cough*

I *need* to get back to my farm, I miss my clay bank =( I hate the idea 
of spending perfectly good money for mud I can mine for free at home.
