Do you have a special collection you really cherish? Maybe it's shiny marbles or a birthday gift full of fond memories. No matter its value, there is a story between you and it. Artifacts are like humanity's shared treasures. They show us the history of the past and cultural memories, open our inner feelings, or guide us to understand important scientific discoveries and inventions that changed our lives. Artifacts are so important to us that we want to know more about them and preserve them for a long time.

As time goes by, all stories are sealed in artifacts. To understand the messages of artifacts, we need a key to unlock them, which is called "scientific analysis." It presents evidence at a microscopic level, helping us explore human development and changes over time. Just like people, artifacts age and can even "get sick." That's why they need regular health checkups too! But did you know? Checking the health of artifacts is remarkably similar to how we do our own health checkups? Both include external analysis, internal analysis, and composition analysis.

We don't just use our eyes to observe. We can also use scientific tools like microscopes to take a closer look at the surface, patterns, and cracks of artifacts. Through these instruments, we can further understand the internal structure and elemental composition of artifacts, helping us speculate about their possible manufacturing processes and origins. Using these scientific tools and techniques makes it easier for us to fix, save, and understand old artifacts. Plus, we can do it more precisely and faster! Now, let's travel back thousands of years, from ancient glass beads to the delicate craftsmanship of the Ye Wang's Koji pottery. We'll learn how to use scientific tools to uncover the secrets of artifacts' structure, materials, and crafting methods, and find ways to protect these cultural treasures, keeping the splendor of history alive forever.
