Eggshell
because
When an egg is boiled in volcanic hot lakes, the high temperatures cause the iron in the eggshell to react with hydrogen sulfide in the volcanic water, forming iron sulfide. Iron sulfide has a black color, which is why the eggshell turns black during this process.
To prevent a hard-boiled egg from cracking while cooking, you can gently place the egg into boiling water using a spoon, rather than dropping it in. This helps to reduce the impact on the eggshell and minimize the chances of it cracking. Additionally, you can add a little bit of vinegar to the water, which can help strengthen the eggshell and prevent cracking.
