The presence of oil on a clock can cause damage, particularly corrosion when metal clock components are touched. Other pollutants can cause oxidization and tarnishing in metal clocks. The cleaning agents used to remove pollutants can result in a chemical reaction with previously used lubricants or cleaning agents or with the materials of the clock.
Applying paint to a clean, smooth (but not glossy) wall is best for proper adhesion. "Before painting, it is important to follow the rule of 'clean, dull, and dry,'" says Dennis Fiorilli, senior ...
A main part of the clock case was given to Pittington Hallgarth Church in 1847. [3] The clock mechanism was fixed in a blank window. Parts of it were rediscovered in 1936 and Dean Cyril Alington launched a campaign to restore it. Mr. J. Armstrong from London, an expert in paint, was engaged in removing the layers of paint down to the original ...
Woodcut of medieval clockmaker, 1568 Lateral view of a Timothy Mason longcase clock movement with striking mechanism, c. 1730. A clockmaker is an artisan who makes and/or repairs clocks. Since almost all clocks are now factory-made, most modern clockmakers only repair clocks.
The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
Typical French craquelure in a portrait from c. 1750, larger and less regular patterns, with curving cracks. Painting systems are composed of complex layers with unique mechanical properties that depend on the type of drying oil or paint medium used and the presence of paint additives, such as organic solvents, surfactants, and plasticizers.
Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does. Anodic films can also be used for several cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add reflected light wave interference effects.
Anti-scratch coating is a type of protective coating or film applied to an object's surface for mitigation against scratches. Scratches are small surface-level cuts left on a surface following interaction with a sharper object.
