Material tray

Name the surface before choosing the remedy.

Material reading is the first Etebu Bench discipline. A cleaner that works on glazed ceramic may punish unfinished wood; a cloth that tolerates water may still bleed dye; a plated screw can look solid while its coating is already thin. The tray below keeps attention on visible evidence rather than brand claims or inherited household folklore.

cloth

nap, dye movement, seam strain, odor, loose fiber

wood

grain lift, end checking, finish cloud, soft dent, joint gap

ceramic

rim chip, glaze crackle, foot ring wear, hollow sound

metal

plating loss, red rust, green bloom, burr, thread damage

glass

clouding, sharp flake, mineral film, stress line

paper

foxing, fold memory, adhesive stain, brittle edge

Material samples arranged on a tabletop for careful inspection — A good tray separates surfaces before it separates opinions. The question is not what the object is called, but how each part behaves under light, air, pressure, and time.
