Science enthusiasts and DIYers, meet your new favorite lab accessory! This massive pack of 1000 glass boiling stones might seem simple, but they're incredibly useful for so many applications. Each 3mm diameter bead is made from soda-lime glass with a polished smooth surface and a softening point of 726°C/1340°F, making them perfect for high-temperature applications without breaking down.
Throw a few into your distillation setup to prevent bumping and ensure smooth boiling, use them as mixing balls for model paints to get perfectly consistent colors, or employ them as filtration media in various lab procedures. The chemical stability means they won't react with most solvents, and the optical clarity makes them easy to see what's happening in your containers. Artists love them for paint mixing, home chemists appreciate them for distillation projects, and hobbyists find endless uses for these versatile little spheres. At about 1000 pieces per pack, you'll have plenty to share or use across multiple projects. If you're not completely satisfied, the company offers a full refund - now that's confidence in their product!
