The Adamantine is a free reaction. I only use it for doors, lava-controlling devices, and as an early-trading item. I'm using it here only as a plot device.

Log of the Overseer of Plantfarmed
Early Spring, 1052
The Elves came, earlier than expected. We had a bunch of dwarves lined up at the depot, ready for the Adamantine ceremony. They didn't seem interested in it, however. They obviously don't know the virtues of this metal. We practically had to stuff a keepsake or two down their throats in order to get them to take it. We kept the rest to give back to the King when the caravan comes in Autumn.
Mid-Spring, 1052
Immigrants! We got a wave of 23, far more than expected. We only had seven bedrooms set up, but we quickly used the extra dwarfpower to power up more alchemical furnaces and finish up more buildings. For example, we finished the upstairs stockpile and created more workshops.
Mid-Summer, 1052
One of the peasants went insane and claimed a craftshop. He demanded turtle shells but I kept telling him that we don't have any, nor are there any in at least 200 kilometers. He babbled on and on so we kept him locked in the shop to prevent any mishaps. He eventually came out peacefully and walked right into the magma pipe.
Early Autumn, 1052
Right after we finished up the workshop complex (but without the walls), one of the dwarves went insane and claimed a clothier's shop. Luckily, he had what he needed and created this self-centered masterpiece:
I'm beginning to hate artists...
Mid-Autumn, 1052
The dwarven caravan came. We traded back the Adamantine keepsakes for some cloth, leather, bags, and seeds. We also bought some pearlash for the future glass industry, and some metal for any trinkets we may need.
Late Winter, 1052
Nothing happened, and progress on completing, or at least improving the fort has been going well. With the new glass furnaces, I've been mesmerized by the sheer shinyness of it...
I have a plan for the Adamantine that was left behind. I've created more glass industry-related workshops and furnaces for the project. It will be magnificent...
