Bookmatch
Two slabs, one mirror image
Bookmatch slabs are cut one after another from the same block, so the veins mirror each other like an open book. Put two side by side and you get a single, symmetrical pattern for a fireplace or feature wall.
Tip: order bookmatch slabs in pairs from the same block number (it is in the product name, e.g. "Block 36"). Call us and we'll confirm the pair is in stock.

The countertop most people compare it with.
Natural stone: granite needs resealing about every 2 to 3 years, and marble etches from lemon juice and wine. Porcelain slabs need neither.
See the full comparison (quartzite, porcelain tile, solid surface, laminate)
| Porcelain slab | Quartz | Granite | Marble | Quartzite | |
|---|---|---|---|---|---|
| What it is | Fired natural minerals, no resin | Up to 90% quartz plus pigment and resin | Natural stone, mostly silicate minerals | Natural stone, mostly calcite | Natural stone, almost all quartz |
| Stains and sealing | Absorbs under 0.08%; no sealing | Non-porous; no sealer | Seal; reseal about every 2 to 3 years | Sealing recommended; acids etch it | Sealing recommended |
| Acid (lemon, wine) | Chemical resistance Class A | — | Resists acid | Etches | True quartzite does not etch |
| Outdoors | Facades and outdoor kitchens; frost resistant | Resin changes color in UV | — | Acid rain weathers it | — |
Solid surface handles heat up to about 175°F and laminate up to about 275°F for short periods; neither is for outdoor use. A dash means we found no source we trust, so we left it blank.

For your fabricator and installer
Anatolia's rules, in short. Share this page with your fabricator. Want the full fabrication manual? Call 502-325-0000.
Cutting
- Use a fabricator with real large-format slab experience. Bridge saw, CNC, waterjet or a combined machine all work.
- Wet cut with diamond tools made for sintered slab, not discs used on quartz or stone. Dry cutting is not recommended.
- Flat, clean, level bench. 6 mm slabs need a support pad under the full length.
- Slow to half speed for the first and last 8 in of each cut.
- Bookmatch: plan the cuts so the pattern lines up across the seam.
Cut-outs and corners
- No square inside corners. Drill the corners first (radius usually 10 mm, never less than the slab thickness), then cut between them.
- Keep sink and cooktop cut-outs about 3 in (7 cm) or more from the edge and about 4 in (10 cm) from each other.
- Leave about 1.5 mm around flush-mount sinks and cooktops.
- No 45° joints on L-shaped tops and no 45° inside edge at the sink: use straight joints.
Support, overhangs and gaps
- The slab is a covering, not a structure: cabinets or a frame carry the load. Keep cabinets level and stable.
- 12 mm on a full support or on reinforcements; 6 mm countertops always on a full, flat support. Never glue onto quartz strips.
- Overhang up to about 6 in (15 cm) without support; 6 to 12 in (15 to 30 cm) with a support; longer runs need a support at least every 24 in (60 cm).
- Holes 6 to 24 in from the edge: halve the overhang. No overhang with an opening closer than 6 in to the cabinet edge.
- Leave 3 mm (1/8 in) at walls and 2 mm at seams.
Gluing and seams
- Built-up edges: two-part epoxy or polyurethane in the slab's color; grind a 1/16 in chamfer after it sets.
- Glue the top to the cabinets, or two pieces together, with an elastic, clear adhesive such as silicone.
- Wet cut, use dust control and wear a respirator: cutting makes silica dust.
Questions people ask
Will the edges chip?
They can. A porcelain slab is hard, but a sharp knock can chip an edge or corner. That is why every edge gets at least a small chamfer or round, and a rounded edge where knocks are likely. Choose 12 mm for kitchen edges and mitred fronts.
Does the pattern run through the slab?
No. The veins are on the face. With Colorsync the body is blended to a matching color, so cut and mitred edges look finished, but the veins don't continue into the edge. A few unglazed, solid-color slabs are the same color all the way through.
Can I put a hot pan on it?
It is rated heat resistant and passes thermal shock tests. Anatolia doesn't publish a maximum temperature, so we suggest a trivet, a good habit on any counter.
Can it go outdoors? Will it fade?
Yes. It is frost resistant, Anatolia lists it for facades and outdoor kitchens, and its warranty covers fading from the sun, indoors and out.
Does it stain? Does it need sealing?
It absorbs less than 0.08% water and scores Class A for stain resistance. It never needs sealing. Wipe spills quickly.
Can it be repaired?
Light scratches can often be worked out. Deep scratches are difficult or impossible to repair, and there is no published chip repair method, so ask your fabricator before you buy.
Will I see the seams?
Our slabs are up to 64 x 127 in, so many tops need few seams or none. Bookmatch slabs mirror the veins across a seam; small shifts in the pattern can still show.
What warranty does it have?
Anatolia's warranty covers its published specs for the life of the original owner in a home, and 10 years for commercial use, on its terms. Damage from impact and a sample-to-slab difference are not covered.
