Large Silicone Sphere Mold

The glacio M-BST-301 is a grey silicone tray that produces six 2.5-inch ice spheres per batch. It suits home bars and casual entertainers who want slow-melting ice for spirits or cold brew.

Flexible BPA-Free Construction

Made from BPA-free silicone, the mould flexes to release spheres cleanly without cracking. The material tolerates dishwasher cleaning, so the tray can be washed alongside regular glassware after use.

Check Freezer Space First

The tray measures 8.5 by 6.75 by 3 inches, so verify that your freezer shelf can accommodate a flat item of that footprint. Ensure you have a level surface for filling and freezing to avoid spills.

Questions about this item

What size ice spheres does the M-BST-301 mold produce?

The mold creates six spheres measuring 2.5 inches in diameter, sized for whisky glasses and large tumblers.

What are the overall dimensions of the M-BST-301 tray?

The tray measures 8.5 inches by 6.75 inches by 3 inches, so check your freezer shelf clearance before buying.

How do I fill the M-BST-301 spheres without overfilling, and what step do people miss?

Use the included funnel to fill each cavity to the shoulder, not the brim, then snap the lid on firmly; water expands when it freezes.
