Ceramic Coating Inside

Can you tell me about the dark rings in ceramic coffee mugs?
When I take my coffee cup of the dishwasher to have dark circles inside. What is that? Is it toxic? "Gone layer for coffee? Should I throw away cups or secure to drink? The cups are clean, no coffee stains. If the porous matter is true, would it not be equally distributed? The rings are black / gray not brown such as coffee. I think there is something more at stake. And I'm not looking to change my coffee habits. I suspect that the lines I'm talking about would be present in the cups of tea drinkers.
Those black rings on their coffee cups exactly match those of the lining of your stomach. Assuming you drink the coffee itself.
