The OP asked about Sulfuric acid carbon because someone who worked at a plant where "chalk" was made said that was the main ingredient. I agree that it doesn't seem to be a recognized industrial name. I'm guessing that is just what they call the raw feedstock within that particular plant. i'm guessing also that sulfuric acid carbon is a byproduct of making sulfuric acid or using sulfuric acid in some other industrial process. In other words, the chalk company is buying some other company's industrial waste. | |

It may be considered as a mixture of carbon and sulfuric acid, which are two independent substances which can be mixed of course. But I don't see the interest in doing this mixture. This mixture will be corrosive like sulfuric acid. It will never be used for any game for children. Too dangerous. So what for ? | |
