This article focuses on restoring the columns and metal trim of a Sessions Baldwin black mantel clock, including identifying original finishes, cleaning methods, and avoiding over‑restoration that reduces historical value.
Understanding the Original Column Finish
Columns coated with tinted clear finish
The columns appear to have been coated with a tinted clear varnish or resin, giving them a warm tone beneath the copper striping. This finish is durable and resistant to alcohol and lacquer thinner.
Copper striping applied over the tint
Two copper-colored painted stripes run across each column. These were part of the original decorative treatment and should be preserved whenever possible.
Finish does not respond to common solvents
Attempts with denatured alcohol and lacquer thinner did not soften the coating, indicating it is neither shellac nor lacquer. Sessions often used tougher factory-applied coatings on metal components.
Columns may look “stripped” but are original
Collectors note that the slightly uneven, striped appearance is original to many Sessions clocks. Removing this finish exposes raw copper and permanently alters authenticity.
Cleaning and Light Restoration Techniques
Soap and water for initial cleaning
Gentle cleaning with mild soap and water removes mold, dirt, and surface grime without disturbing the original finish.
Use 0000 steel wool sparingly
Very fine steel wool can brighten the lighter copper areas, but should only be used on the brightest sections to avoid stripping the entire column.
Avoid aggressive polishing
Over-polishing removes the factory tint and copper striping, leaving a plain copper tube that no longer resembles the original Sessions finish.
Preserve patina for collector value
Collectors prefer clocks that show age. Removing patina or original coatings can reduce value and historical character.
Restoring Other Metal Trim and Accents
Rub‑n‑Buff for worn handles and feet
Rub‑n‑Buff metallic wax is recommended for restoring worn decorative metal parts. It provides a convincing metallic sheen and dries quickly.
Seal restored parts with lacquer
After applying Rub‑n‑Buff, a light lacquer coat protects the finish and prevents premature wear.
Verde antique copper finish on lintel
The lintel originally had a verde antique copper effect. While the exact factory formula is unknown, similar finishes can be recreated using layered green and copper patina products.
Do not strip original verde finish
If any of the original verde coloration remains, it should be preserved rather than replaced.
Structural Considerations During Restoration
Feet attached with small brads
Sessions feet are typically secured with small brads. If the holes have enlarged, inserting a glued round toothpick provides fresh wood for re‑nailing.
Inspect for mold and moisture damage
Clocks stored in damp environments may have mold or softened wood. Cleaning and drying should precede any cosmetic restoration.
Evaluate before refinishing
Many restorers recommend minimal intervention unless the finish is severely compromised. Originality is often more desirable than a “like new” appearance.
Best Practices for Preserving Sessions Mantel Clock Columns
Retain original finishes whenever possible
The tinted coating and copper striping are part of the clock’s factory appearance and should not be removed unless severely damaged.
Use gentle cleaning methods first
Soap, water, and light steel wool on select areas are usually sufficient to restore appearance without harming original materials.
Enhance but do not replace patina
Patina contributes to authenticity. Over‑restoration can make the clock look modern and reduce collector appeal.
Consult examples of original Sessions finishes
Comparing with intact Sessions clocks helps guide restoration choices and avoid accidental removal of original decorative effects.
FAQs
What was the original finish on Sessions mantel clock columns?
A tinted clear coating with copper striping, not plain polished copper.
Can the original tint be recreated?
It is difficult to match exactly; preservation is preferred over refinishing.
Is Rub‑n‑Buff appropriate for restoring metal trim?
Yes, it provides a convincing metallic look and is commonly used by restorers.
Should the columns be stripped to bare copper?
No—this removes the original factory finish and reduces historical value.
How should worn feet be reattached?
Use a glued toothpick in enlarged holes to create a new surface for brads.
