Homonym: refinement (Purification)
Refinement is the process of improving something by making small changes or adjustments. This can apply to various fields, such as art, technology, or even personal skills. For example, a painter may refine their technique to create more detailed and expressive works, while a software developer might refine a program to enhance its performance and user experience.
In the context of materials, refinement often refers to purifying substances, such as extracting gold from ore or processing crude oil into usable fuels. This process removes impurities, resulting in a higher quality product that meets specific standards and requirements.
