Exhaustive Glossary of Quartz & Quartzite Countertop Terms
1. General Countertop Terminology (Applies to Quartz & Quartzite)
Countertop
A horizontal work surface installed on cabinetry, commonly used in kitchens and bathrooms.

The depth of a slab, typically 2cm (¾”) or 3cm (1¼”).
Edge Profile
The shape finished along the exposed edge of a countertop (e.g., eased, bullnose, ogee).
Seam
The joint where two slabs meet; visibility depends on material, pattern, and fabrication quality.
Backsplash
Vertical surface installed behind countertops to protect walls from moisture and stains.
Overhang
The portion of the countertop that extends beyond the cabinet face.
Substrate
Support material beneath thinner countertops, often plywood or MDF.
Cutout
A section removed from the slab to accommodate sinks, cooktops, or fixtures.
Reveal
The amount of cabinet face visible beneath the countertop edge.
2. Quartz Countertops – Material & Composition Terms
Quartz (Engineered Stone)
A man-made countertop material composed of ~90–95% natural quartz crystals combined with resins and pigments.
Resin Binder
Polymer material used to bind quartz particles together.
Pigment
Coloring agents added to quartz during manufacturing.
Engineered Stone
A category of materials (including quartz) manufactured using crushed stone and resin.
Non-Porous
A surface that does not absorb liquids, making quartz stain-resistant.
Homogeneous Material
Consistent color and pattern throughout the slab.
Batch Variation
Minor differences in color or pattern between manufacturing runs.
Veining (Engineered)
Artificial veins designed to mimic marble or natural stone.
3. Quartz Countertop Design Terminology
Marble-Look Quartz
Quartz designed to resemble marble with soft or dramatic veining.
Concrete-Look Quartz
Quartz with a matte or textured appearance mimicking concrete.
Solid Color Quartz
Quartz with uniform coloration and minimal pattern.
Pattern Density
The concentration of particles or veining in a slab.
Directional Veining
Veins that run in a consistent direction, requiring careful slab layout.
Bookmatching (Quartz)
Mirroring two slabs so veining appears symmetrical.
Finish
The surface texture of quartz:
-
Polished – Glossy and reflective
-
Honed – Matte, smooth finish
-
Leathered – Textured, tactile finish (less common in quartz)
Edge Detail
Decorative shaping of the slab edge for aesthetic appeal.
4. Quartz Countertop Fabrication Terminology
CNC Machine
Computer-controlled machinery used to cut and shape slabs precisely.
Waterjet Cutting
High-pressure water mixed with abrasives for precise cuts.
Template
A digital or physical outline of the countertop layout used for fabrication.
Dry Fit
Test assembly of pieces before final installation.
Lamination
Bonding two pieces together to create a thicker edge appearance.
Mitered Edge
A 45-degree joint creating the illusion of a thicker slab.
Eased Edge
Slightly softened square edge (most common for quartz).
Polishing
Refining the surface or edges to achieve a smooth finish.
Sink Cutout Reinforcement
Added structural support around sink openings.
5. Quartz Countertop Installation Terminology
Leveling
Ensuring cabinets and countertops sit perfectly flat.
Shimming
Using spacers to correct uneven surfaces.
Adhesive
Epoxy or silicone used to bond quartz to cabinetry.
Seam Setter
Tool used to align and tighten seams during installation.
Color-Matched Epoxy
Tinted adhesive used to blend seams invisibly.
Undermount Sink Installation
Sink mounted beneath the countertop surface.
Overmount (Drop-In) Sink
Sink that rests on top of the countertop cutout.
Caulking
Sealing joints between countertops, walls, or sinks.
Cure Time
The time required for adhesives to fully harden.
6. Quartz Kitchen Countertop Terminology
Island
Freestanding cabinet topped with quartz, often requiring large slabs.
Waterfall Edge
Quartz extending vertically down the sides of an island.
Cooktop Cutout
Opening for gas or electric cooking surfaces.
Heat Resistance (Quartz)
Moderate heat tolerance; not heat-proof.
Integrated Backsplash
Quartz backsplash fabricated from the same slab.
Overhang Support
Brackets or corbels supporting extended quartz surfaces.
7. Quartz Bathroom Countertop Terminology
Vanity Top
Quartz countertop designed for bathroom vanities.
Integrated Sink
Sink molded or seamlessly joined with the countertop.
Faucet Hole Drilling
Pre-drilled holes for plumbing fixtures.
Splash Guard
Short vertical quartz section behind sinks.
Moisture Resistance
Quartz’s non-porous nature prevents water absorption.
8. Quartzite Countertop – Material & Stone Terminology
Quartzite
A natural metamorphic stone formed from sandstone under heat and pressure.
Natural Stone
Material quarried directly from the earth with inherent variation.
Metamorphic Rock
Stone transformed by heat and pressure, increasing hardness.
Porosity (Quartzite)
Natural stone characteristic requiring sealing.
Fissures
Naturally occurring lines or separations in stone.
Movement
Natural variation in color, veining, and pattern.
Hardness
Quartzite is extremely hard, often harder than granite.
9. Quartzite Countertop Design Terminology
Marble-Like Quartzite
Quartzite varieties resembling marble (e.g., Taj Mahal, Calacatta quartzite).
Linear Veining
Veins running lengthwise across the slab.
Organic Patterning
Irregular natural formations unique to each slab.
Color Range
Natural hues including whites, creams, grays, greens, blues, and golds.
Slab Selection
Choosing individual slabs due to high variation.
Bookmatching (Quartzite)
Mirroring natural veining across slabs.
Natural Finish Options
-
Polished
-
Honed
-
Leathered
10. Quartzite Fabrication Terminology
Diamond Blade Cutting
Required due to quartzite’s extreme hardness.
Hand Finishing
Manual polishing of edges and details.
Reinforcement Rods
Steel or fiberglass rods added to prevent cracking.
Vein Orientation Planning
Strategic layout to preserve natural veining.
Edge Build-Up
Thickened edges using stone lamination.
Crack Stabilization
