A lot of heat and a lot of pressure would be a start, but then there’s a time factor as well. The heat and pressure mess around with the rocks mineral constituents, but the real “magic” begins as those minerals start recrystallizing. In time (geologic time) that recrystallization makes a much harder rock.
I honestly don’t know if the process can be sped up. I’m thinking of something like firing bricks, but bricks are made with specific ingredients and certain impurities are specifically excluded because they hurt the manufacturing. When you start with shale, lord knows what mother nature threw into that specific specimen and how she arranged it.
I guess the easiest way to get shale harder might be to crush it finely, mix it with water and bake it. If you’re lucky the clay minerals will find each other and form a strong matrix. It wouldn’t be slate, or even a rock anymore, but bricks are handy sometimes.
Shale is not a good building material, it’s too friable (crumbly). Slate starts off as the same rock ans shale except it undergoes a bunch of heat and pressure which makes it much less friable and an excellent material for things like roofing tiles and mantles.

I saw this on the news and my mind took me to Thebes.

The common mistake - disputing a credit card charge and initiating a chargeback.
I wonder if Kennedy has moved off of bear “pranks” and has turned to crabs.

We all are. It’s one of the bonds that keeps civilization alive. Keep searching !
That’s what the three shells are for.
Calculations are simpler if …….. you assume a spherical cow!
I believe it is an herb.
Waiting for the gang to leave for their nightly feed. They didn’t leave until after sunset this evening.
The little guy tries an evasive maneuver against the hawk.
Most every night, raptors line up for the bat buffet at Bracken Cave Preserve. The bats pour out of the cave for about 3 hours. he bats exiting is a swarming defense strategy to not getting eaten. When you see a young or sick bat stray from the main cloud of bats, the raptors take advantage of the opportunity. Here is one of several hawks that feeds daily before dusk. After dusk, the owls own the skies here in our little Texas wildlife preserve.
Here’s a happy snap from a recent emergence at Bracken Cave Preserve. These are Mexican Free-tailed bats that are part of the maternal colony that summers here in the Texas hill country. We host the colony of approximately 20 million bats from spring to fall. It takes 3+ hours for colony to leave the cave and they’re pretty orderly about it.

Looks like chicken mole. Hope to try it sometime (maybe at a more simple restaurant).
