Spotting Fire Mark Reproductions
A Collector's Guide to Identifying Authentic Fire Marks
As fire marks have become increasingly valuable to collectors, the market has unfortunately been flooded with reproductions, replicas, and outright fakes. Learning to distinguish authentic fire marks from reproductions is essential for both new and experienced collectors. This guide provides practical techniques and specific examples to help you make informed decisions.
Remember: When in doubt, consult with experienced collectors or FMCA members before making a purchase. The cost of expert verification is minimal compared to buying a fake.
Understanding Metal Composition
Authentic Materials
- • Cast Iron: Most common, magnetic, develops rust
- • Lead: Heavy, soft, non-magnetic
- • Tin: Lightweight, non-magnetic
- • Zinc: Medium weight, non-magnetic
Red Flags
- • Aluminum: Too modern (post-1890s), very lightweight
- • Cast Brass: NO authentic fire marks were made of brass
- • Modern alloys: Unusual weight or appearance
The Magnet Test
Always carry a small magnet when examining fire marks. Only iron is magnetic. If a mark looks like iron but isn't magnetic, it's likely a reproduction made from a different metal.
Physical Characteristics to Examine
Mounting Holes
Check the location, number, and alignment of mounting holes. Reproductions often have:
- Holes in the wrong locations
- Too many or too few holes
- Perfectly aligned holes (originals were often hand-drilled)
- Modern drill marks versus hand-drilled characteristics
Size and Proportions
Reproductions frequently get the dimensions wrong:
- Compare to known authentic examples
- Check thickness - reproductions are often too thin or thick
- Verify overall proportions match originals
- Look for consistent depth of relief in raised elements
Edge Treatment
Examine the edges carefully:
- Look for grinder marks on edges (sign of modern production)
- Check for filing or finishing marks
- Original cast edges have different characteristics than machined edges
Understanding Rust and Patina
Authentic Aging
- Old iron rust: Dark brown, sometimes almost black
- Natural patina: Develops unevenly over decades
- Wear patterns: Consistent with mounting and exposure
- Layers: Multiple layers of paint or rust indicate age
Artificial Aging
- New iron rust: Bright orange color
- Gray appearance: Often indicates recent production
- Glossy paint: Used to mask poor quality iron
- Simulated rust: Cast into the reproduction itself
Pro Tip: Some reproductions have "rust" that's actually part of the casting - look closely to see if the rust texture is raised above the surface rather than eating into it.
Common Reproductions to Avoid
| Manufacturer/Type | Identifying Features |
|---|---|
| Virginia Metal Crafters | Look for specific casting numbers on the rear |
| Wilton Products | "Wilton" spelled out on the back |
| BU# 420 (Hicksville) | Not an authentic fire mark despite appearances |
| Modern Gift Shop Items | Often aluminum, perfect condition, modern mounting |
Note: This is not an exhaustive list. New reproductions appear regularly, so staying informed through FMCA newsletters and member communications is essential.
Best Practices for Collectors
Before Buying
- Research the specific mark thoroughly
- Compare with authenticated examples
- Ask for provenance or history
- Get a second opinion from experienced collectors
- Be wary of "too good to be true" prices
Red Flags to Avoid
- Perfect condition on supposedly old marks
- Multiple identical marks available
- Seller can't provide history
- Unusual materials or construction
- Price significantly below market value
