The reference / Material surfaces
Surface texture changes how an object interacts with light, contact and wear.
01. Establishing a reference
Surface texture changes how an object interacts with light, contact and wear. A coating and its substrate behave as a system. A useful working note records the context and the purpose of the study. Keep the details that explain what was noticed, and distinguish them from ideas that emerged later.
A coating and its substrate behave as a system. This point should be read together with the stated reference and the conditions of the record.
02. Describing the setup
A finish should be described with a measurement method. When revisiting a series of observations, begin with the original context. Record the order of the work and keep the first descriptions alongside any later interpretation.

03. Reading the first observation
The next pass through material surfaces focuses on comparison. Lighting direction affects the appearance of texture. Look for the relationships between the details and retain enough context for another reader to understand the study.

04. Working with variation
Surface texture changes how an object interacts with light, contact and wear. A coating and its substrate behave as a system. A useful working note records the context and the purpose of the study. Keep the details that explain what was noticed, and distinguish them from ideas that emerged later.
Roughness describes small-scale surface variation. This point should be read together with the stated reference and the conditions of the record.
