Tile materials, explained
Melamine — the workhorse
Most complete sets in the world are melamine: hard, light, washable and cheap to engrave well. Yellow Mountain Imports builds its entire range on it. Melamine's limits are aesthetic — it cannot do the layered, translucent backs of premium acrylic — and tactile: a lighter clack. For weekly play on a budget it is the rational default.
Acrylic — the designer standard
Acrylic is denser, takes deeper and crisper engraving, and can be layered so the back of the tile carries colour and pattern through the tile itself. Oh My Mahjong, The Mahjong Line and Linda Li's Artisan line are acrylic. You pay roughly two to four times melamine prices for the same game — and buyers in this tier consider the table presence the product.
Resin — the handmade route
Crisloid's tiles are resin, made in Rhode Island. Resin suits small-batch and custom work: printed or engraved designs, unusual sizes, collector editions. It is how a US maker competes — on craft, not on container-load pricing.
Bamboo & bone — the vintage material
Pre-war and mid-century sets paired a bone (later, substitute materials) face with a bamboo back. Genuine sets now trade as antiques at roughly $800–$2,500 depending on carving and completeness, and modern 'bamboo-look' tiles are melamine or acrylic wearing the pattern. Buy vintage for the object and the history; grade condition tile by tile, or buy from a specialist who already has.
What to avoid
Thin, printed (not engraved) faces that will wear smooth; unnamed plastics in no-brand listings with no replacement-tile path; and any set that will not tell you what its tiles are made of. Material is printed on every product page here because it is the first spec a maker should volunteer.
