The salt block was the hit of the party. I heated it on the stove top. Since the store was electric, I used a flame tamer between the block and the stovetop. (On my own gas stove, I would not have needed the flame tamer and would have just set the block on the iron framework above the burner.) I heated the block slowly for about 20 minutes and then at the maximum for that burner. (I think I actually got the temp higher than it needed to be, out of fear that it wouldn't get hot enough. Turned out there was no reason whatsoever for any such fears!) I spread a bit of olive oil on the salt block just before starting to grill.
I peeled shirmp (all except the end of the tail), tossed them in olive oil and chopped garlic, and threaded them on rosemary skewers. (I got three shrimp per skewer, which meant I could lay three skewers on the block at a time.) It tooke just a couple of minutes per side, and the shrimp were extremely succulent. (I used medium-size shrimp from the grocery, about 30 to the pound, caught on the East Coast. Here in Charleston, we do get marvelous local shrimp in our own season. I would use a slightly larger sized shrimp, and local ones, if I could get them. However, these were still very close to the best shrimp I've ever eaten. They were amazingly juicy!). They did "pull" salt out of the block.
I did dry the shrimp thoroughly before tossing them in the oil; the various instructions I found were stern about not putting watery things (like butter) on the salt block.
The block took about an hour to cool down. I believe I could have cut the heat off 45 minutes earlier and not slowed down the cooking at all; I will definitely try to use a gentler heat next time.
The block itself darkened a bit; it is not as translucent as before. It has a mark on one side from the flame tamer. It cleaned up very easily - rubbing with the dish bush under running water, but the cooking side now seems to have a "cure" or a "seasoning" - kind of a different, slicker, surface.
One other thing - the block did crack a bit and we now have a little chunk out of it that we can grate over something we want to salt. How fun!
It was definitely the hit of the party - it would be fun to cook your own, kind of like fondue. In fact, I'd bet you could bring a heated block to the table (with something under it to keep from frying your good dining table!) and people could do their own cooking.
