Descriptions:
  1. There are two kinds of commonly used materials for making glass balls: Soda Lime Glass & Borosilicate Glass.
  2. Soda-lime glass is known as chemically inert. It is resistant to alkaline solutions. The balls made of soda-lime glass have good electric and corrosion-resistant properties but can not bear the thermal shock. The melting point is about 700C.
  3. Borosilicate glass is highly chemical and heat resistant. Borosilicate glass balls are dimension stable with a melting point of about 800C.
  4. Glass balls are especially useful for check valves, visual flow equipment, low-speed bearings, and many labs and experimental applications.
  5. Notice: Please confirm the Ball Diameter you are ordering.

Glass boiling stones act as localized nucleation sites, enabling consistent bubble formation to regulate vaporization and prevent erratic boiling or bumping. Their inert, smooth surface promotes controlled phase transitions without introducing impurities. They ensure that equilibrium is reached more predictably.

I wish they had a bit more weight to them but other than that they're alright.

I needed some sort of clear spheres to make glowing eyes for a giant animatronic spider. I was able to fit a standard 5 mm LED inside and they worked great! As I needed them to be shiny black when the LEDs were not lit, I sprayed them with automotive brake light tinting spray achieving the desired effectIt's possible I will need more eyes for future projects and would definitely order more.

I add thees to paint bottles and markers to mix the paint. They work great. I bought glass because the metal ones can rust.

Thought these would mix contrast / washes well but seemed to get stuck inside bottle and doesn’t have the mixing ability of the metal balls

Great for mixing balls for payment, and i dont have to worry about rust like stainless steel can get sometimes
