Quick Answer
Yes, you can use rocks from the ocean for boiling, but you need to make sure they are free of any contaminants and can withstand high heat.
Choosing the Right Rocks
When selecting ocean rocks for boiling, look for those that are hard, dense, and have a high heat capacity, such as granite or basalt. Avoid rocks with cracks or soft spots, as they can shatter or break apart when heated. Also, make sure the rocks are free of any visible signs of marine life or pollution.
Preparing the Rocks
Before using the rocks for boiling, wash them thoroughly with clean water to remove any dirt or debris. Then, heat the rocks in a fire for about 10-15 minutes, or until they reach a temperature of around 600-800°F (315-427°C). This will help to purify the rocks and improve their heat transfer properties.
Boiling with the Rocks
To use the rocks for boiling, place a container filled with water on top of the heated rocks. The heat from the rocks will transfer to the water, bringing it to a boil. You can also add food, such as seaweed or shellfish, directly to the rocks for cooking. Be cautious when handling the hot rocks, and use protection such as gloves or a towel to avoid burns.
