This is more something that should go to NoStupidQuestions. Your answer is that it tastes stony. Discussion ends there.

Tums. Tums, and other similar antacids, are calcium carbonate. Calcium and carbon. That’s what makes limestone limestone.

Rock

When I was being taught geology the lecturers would occasionally lick a rock. I still don’t know if it was a joke as most rocks taste pretty neutraock If you are interested, give it a lick, it can’t do you any harm. Although bear in mind that limestones are a broad church, so you may need to lick a few to get an idea of the breadth of their taste nuances.

Unless a rock contains ores then they are usually OK to taste so branch out after that.

I work in limestone quarries every day. The dust and grit gets everywhere, and almost every day I will get some in my mouth. Sometimes pieces that are about the size of a skittle somehow make it into my mouth (no. They do not taste like lime Skittles)

The taste isn’t the problem, it’s the gritty texture that makes it feel like you’re grinding away at your teeth. The taste is similar to steak seasoning. I keep some unflavored gum with me and chew it when I get some in my mouth. This allows me to enjoy the salty/savory flavor while getting past the horrible texture. If only they made steak-flavored chewing gum.
