Vintage Pittsburgh Clear Glass Blocks – 5 3/4 X 5 3/4 X 3 7/8 Inches, Used

These are vintage glass blocks from Pittsburgh, clear in color, and they measure 5 and 3/4 inches square by about 3 and 7/8 inches thick.

They're used, so there might be some cosmetic wear, but they're still solid and fully functional.

Great for retro renovations, DIY window projects, or adding that old-school industrial vibe to a space.

No cracks or damage that affects usability—just normal character from age.

If you're into mid-century builds or just need some unique blocks for a project, these are worth grabbing.

Exterior color is clear, brand is Pittsburgh.

Cool little piece of architectural salvage.
