Meaning: This quote by Robert Duncan draws an interesting parallel between the formation of glass and the resetting of time, emphasizing the enduring nature of glass and its potential for long-term preservation. To fully understand the meaning behind this quote, it is necessary to delve into the properties of glass and the process of its formation, as well as the significance of time in relation to both the physical and metaphorical aspects of glass.

Glass is a remarkable material that has been used by humans for thousands of years due to its versatility, transparency, and durability. The formation of glass involves the melting of various raw materials, such as silica, soda ash, and limestone, at high temperatures to create a molten liquid that can be shaped and cooled into solid form. This process of melting and solidification is akin to the resetting of time mentioned in the quote, as it marks the beginning of a new state for the glass material.

When glass is formed from its molten state, it effectively captures a snapshot of time, preserving the arrangement of its molecules and atoms at the moment of solidification. This frozen-in-time quality of glass is what Duncan alludes to when he compares it to starting a clock. In a sense, the formation of glass resets the "time" for the material, encapsulating within it the conditions and characteristics of its creation. This frozen moment in time allows us to examine and analyze the structure and composition of glass billions of years later, providing valuable insights into its origins and history.

Furthermore, the quote highlights the enduring nature of glass, suggesting that the reset time at its formation allows us to determine its properties and characteristics even after billions of years. Unlike many other materials that degrade or decompose over time, glass has the potential to remain relatively unchanged for incredibly long periods. This longevity and stability make it an invaluable resource for scientists, archaeologists, and historians who seek to understand the past through the examination of ancient glass artifacts.

Metaphorically, the quote can also be interpreted as a reflection on the enduring significance of glass as a material that transcends time. Throughout history, glass has been used to create objects of both practical and artistic value, serving as a window into the past and a medium for human expression. The resetting of time at the formation of glass symbolizes its ability to transcend temporal boundaries, allowing us to connect with the craftsmanship, creativity, and ingenuity of individuals who lived long ago.

In conclusion, Robert Duncan's quote eloquently captures the enduring nature of glass and its significance in preserving the passage of time. The formation of glass from melting represents a reset of time, enabling us to examine and appreciate its properties billions of years later. Whether viewed through a scientific, historical, or metaphorical lens, this quote underscores the lasting impact of glass as a material that captures and transcends time, inviting us to ponder its timeless allure and significance in human culture.
