Tumbled Glass for Crafts

1 4

Mid-century glass was made differently.

Before mass production, American glassmakers used thicker walls and deeper pigments, and it shows in the color and weight of every piece. We hand-collect genuine sea glass from NYC's historic shorelines, tumble vintage glass in Brooklyn for crafters, and sort it all by color and size. Every source is vintage. Nothing is manufactured new.

Common Questions

Is this real sea glass?

Yes, depending on which product you choose. Genuine sea glass is frosted by the ocean over decades and hand-collected from NYC's historic shorelines. Tumbled glass starts as recovered vintage glass and is tumbled in-house in Brooklyn to a smooth, frosted finish. We never sell dyed, painted or newly manufactured glass.

What's the difference between genuine and tumbled glass?

Genuine sea glass is ocean-tumbled, with no in-house processing. It's rarer and more irregular, and the best choice for jewelry and collections. Tumbled glass is more uniform and more consistently available, so it suits bulk crafts, mosaics and event decor.

What can I make with it, and which size should I buy?

Customers use it for jewelry, resin art, mosaics, framed art, vase displays and wedding decor. Micro and extra small pieces suit jewelry and resin. Medium and large pieces suit mosaics and shadow boxes.

How long does shipping take?

Orders ship from Brooklyn via USPS within 1 to 3 business days. Standard US delivery takes 3 to 7 business days once shipped, and every order includes tracking. Shipping is free on US orders of $35 or more.
