I know right? It must have seemed like a miracle material. You can make fireproof fabrics and blankets, insulation bats, brake pads, ceramic tiles, roofing, even sheet rock for buildings. Its durable, UV safe, water resistant, pest-resistent, rot-resistent and machine workable. It doesnt require any complex chemistry to synthesise, you can just dig it right out of the ground.
And its toxicity is so insidious. It doesnt kill or even make you sick right away. Not the next year even, like silicosis. No, the bastard waits 25-35 years, and then drowns you in your own self-destructing lung tissue.
The danger comes more from inhalation of particles that break off. The asbestos fire gloves contain the asbestos laced fabric sheathed inside cloth material to help contain the particles. They're also considered consumable, because handling something on fire will likely destroy the outer fabric (for example, a lithium battery powered device combusting, and placing it into a fire-safe bag).
