This vintage chemistry textbook is mainly for learning high - school chemistry. You can read it cover - to - cover to learn the knowledge, or use it as a reference when you're stuck on a topic. When handling the book, be gentle because the binding is loose. Avoid getting it wet as it may damage the old pages. To maintain it, store it in a dry and cool place. If you want to protect it further, you can put it in a book sleeve. Don't write on the pages to keep its original state.
