Interpretation / 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. Roughness describes small-scale surface variation. 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.
02. Describing the setup
A coating and its substrate behave as a system. 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. A finish should be described with a measurement method. 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. Roughness describes small-scale surface variation. 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.
Lighting direction affects the appearance of texture. This point should be read together with the stated reference and the conditions of the record.
Quick reading check
Which note provides useful context?
What does this reference describe?
Surface texture changes how an object interacts with light, contact and wear.
What should accompany a measurement?
Roughness describes small-scale surface variation.
Why keep the setup in the record?
A coating and its substrate behave as a system.
How should a comparison be read?
A finish should be described with a measurement method.
What belongs in a working note?
Lighting direction affects the appearance of texture.
Are the plotted values live readings?
The diagrams and tables here use illustrative reference data. They are included to explain a reading method, not to report a live instrument.
What changes between sessions?
Review the reference, setup and conditions before combining records from different sessions.
Where should an interpretation begin?
Begin with the observation and its limits. An explanation should remain distinct from the original record.
