Shut-off valves with scale buildup leak but re-seal?

I've noticed this in the past and have noticed this recently too. A globe/gate valve has scale buildup (near a leaking packing nut). I tried tightening the packing nut but it wouldn't budge. The valve still leaked small slow drops, even after a few days. But I noticed after a few weeks, this leak was non-existent. Have you ever noticed this? Is this because the minerals/scale in the water have essentially plugged the leak?

yes, but they sell packing material that with the valve shutoff, you can take the packing nut off and put more packing in and then tighten the nut back down...leak fixed..
