Billiard Slate Guide

Billiard slate is the natural stone that forms the playing surface of every serious pool, snooker and carom table. It has to be flat, dense and dimensionally stable to fractions of a millimetre, because the ball roll follows the surface. This guide covers everything a table manufacturer or importer needs to specify, source and import it — sizes, thicknesses, CNC machining, tolerances, quality inspection, packing, shipping and installation.

This guide is about the product, not the origin. It explains the slate itself — how pool, snooker and carom slate differ, what thickness and flatness really mean, how CNC machining controls the holes and pocket cuts, and how to buy direct from a factory that ships to 30+ countries. Where the rock comes from and why the geology suits table use lives in the Jiujiang Slate Guide; the roof side of the same stone is covered in the Roofing Slate Guide.
