Genuine Black Slate Coasters (4x4) | Hand-Crafted Laser Engraved Designs
Custom Hand-Crafted Slate Coasters (4" x 4")
A personal note from Chad (Owner & Crafter):
I take immense pride in sourcing deals, but these are special—because I make them myself. These aren't mass-produced plastic discs; these are slabs of genuine Black Slate, laser-engraved right here in my workshop in Burlington, KY.
Whether you're looking for sports logos (like my popular Cincy designs), fierce wildlife, or intricate fantasy art, the laser etching is permanent—it won't fade or peel like paint. I hand-sand the edges of every coaster to reduce sharpness while keeping that rugged, natural stone look. Plus, because it's real earth-mined slate, some lucky coasters feature natural deposits of Pyrite ("Fool's Gold") that sparkle in the light. A "neat little extra" you won't find in big-box stores.
Material Insight: Why Choose Slate?
According to geologists and home interior experts, Slate is a fine-grained, foliated metamorphic rock. It is uniquely suited for coasters because:
- Thermal Stability: It does not warp under the heat of a coffee mug.
- Natural Aesthetics: The uneven cleavage (cleft) of the rock provides grip and prevents "vacuum seal" sticking to the bottom of a wet glass.
- Longevity: Laser engraving physically ablates (vaporizes) the surface layer of the stone, revealing the lighter gray interior. Unlike screen printing, this design is structurally part of the stone and cannot wash off.
