Marsh Refinery WIP:
I basecoated it with grey primer for mortar (and the interior) so I could save some steps, but unfortunately I didn't add the floor until afterward. Anyhow, I drybrushed with "Tuscan Red" and "Red Apple" with the latter being VERY light highlights. I wanted it to look old, but not decrepit as the story states that it's one of the few buildings still in reasonably good repair.
Anyhow, did the wood tones with a 3 color treatment, used OldBen1's patented (and oft-pilfered) milk jug windows instead of the glass blocks I had originally planned, primarily due to the ABSOLUTE burnout on these buildings I'm experiencing at this point.
But that wasn't enough. I used some Sculpey and Plasticard to make a gold brick form, a small crucible, and a stack of gold ingots. I used 2 pill bottles and some straws to create two chemical tanks for precipitation tanks (assumed agua regia process) as well as a yogurt container for a smelting kettle (including tin top for molten gold). Finally, I used some Plasticard, a straw, and balsa to make what I'm guessing is a power panel of some kind.
All in all, pretty happy with most of it. Still some work to do, but it's almost where I want it to be.
