Actually, silica content of black locust is zero

Not the ones in my yard! Sparks are visible when you cut the wood. The
chain has to be sharpened frequently. Chains don't last all that long.
Also quite a bit of ash is left. But it burns long and hot.

Yes, but the wood has very high silica content and will dull a saw chain
quickly. Just a nuisance.
