“You used the CM352,” he said.
Elara knew what it was. CM352 was a strange hybrid: a corrosion inhibitor originally developed for reinforced concrete bridges, later adapted for archaeology. It wasn't just a sealant. It was a chelation agent with a specific electrochemical trick—it targeted free chlorides while bonding to the ferrous surface at a molecular level, forming a hydrophobic film only a few nanometers thick. cm352 corrosion inhibitor
Her colleague, Javier, had already gone home. On his desk, he had left a small, unmarked vial filled with a milky-blue liquid. Scrawled on a Post-it note: “CM352. The last resort.” “You used the CM352,” he said

But it was stable . When she gently brushed a fiber probe across the edge, it didn’t crumble. It sang a low, metallic hum.
The protocol was delicate. She couldn't immerse the sword; it would disintegrate. Instead, she used a capillary applicator. Touch by touch, she traced the inhibitor into the micro-fractures.
