Add a layer of hot water and let it slake overnight.  After that you can put it all in a blender or use an immersion blender to chop up any hard chunks of binder.  Finally sieve it to remove any small chunks that didn't dissolve.

When we had that problem at school, the hard chunk of glaze was placed between two pieces of canvas and pounded with a hammer. Occasionally it was  dumped on a screen, sifted and the larger chunks returned for pulverizing until they were small enough to mix and screen.

Also, a chisel was useful in breaking glaze stuck in a jar.

I use Liam's method. If it is in a 5 gallon bucket, I use hot water, soak it and as soon as soft enough, I use a jiffy mixer bit on my drill, and grind it up. When I moved back to Montana from Texas a few years ago, I tried to dry up all my glazes before putting them on a truck.

Depending on the quantity, you might break it up and put small chunks in an old blender or coffee grinder to pulverize it, then sieve as necessary and regrind...

If it still has some moisture in it, carve it out of the pot with a loop tool.  One made with a flat blade, not a wire one.  Let it dry thoroughly, then re-wet as @liambesawsays.
