- Basalt Fibre (bonded with recycled PET) is also being used in yacht construction inplace of glass fibre

- Is this any safer than asbestos if it gets broken up?
- > First the basalt is melted at a temperature of 1,400 °C (2550 °F). The molten rock is then extruded through small nozzles for the production of filaments of basalt fibers.
As a 3D-printer user, I flinched.
- In-situ produced basalt fiber reinforced butyl rubber is likely to be one of the major building materials on Mars or the asteroids if humans ever get there.

- We manufacture cast basalt that's used in applications that have a lot of wear and tear. This is pretty cool to see another application of basalt!

- This makes me think about Vinylon[1] and this article from Reuters[2]

- Just answering my own question: Is this be used for bullet proof vests?
Heavier than carbon fiber and kevlar with lower tensile strength than both.
So, no, not unless it's much cheaper.
- rock wool, and other names are used for basalt fibre insulation, which is quite brittle, and turns to dust with very little manipulation must be produced useing a different chemistry and process, but the same bulk feed stock, which I believe is just a certain type of foundry slag that is dumped in the millions of tons per anum range, while still molten, which is where the incentive comes from to utilise it then and there
- I'd guess within a couple of centuries, someone will figure out a material for jeans that doesn't tear between the legs.

- Isn’t Rockwool the unwoven version of this?
- just thinking about this makes me itch. A lot of heat wrap for exhaust pipes is made of this stuff. Works pretty well though, just not a ton of fun to work with.
- Isn't this basically fiberglass?

- This is used in some skateboards and snowboards. Lighter weight, stronger, flexier than wood and doesn't splinter like carbon fiber

- I wonder how long it takes for the basalt glass to begin to crystalize?

- What could regular people do with it?
Oven gloves? Anti-stab vests? Gloves for working with strong chemicals?

- Rockwool is molten basalt /slag spun into wool-like fibers and then bound with resin
- I think I have seen it being used in Snowboards
- So, I can sew a battle west made of rock?!
Finally \../
- Asbestos 2.0?
- I imagine this is bad news to breath in?
