What are the small black balls inside a floating thermometer (the kind used in wine/beer making)?

While making wine at home we dropped the floating thermometer (similar to the one pictured below) into the wine. It hit the bottom and cracked. The thermometer is still intact, but some of the outer glass and black balls got into the mix. We plan on filtering the wine, so we're not worried about the glass. However, we don't know what the black balls are made of and if it will still be safe for consumption. Are the contents of the thermometer dangerous? Is our wine ruined?

FLOATING THERMOMETER

Winemaking thermometers don’t contain mercury, but they do contain volatile chemicals, like toluene. If you break one into your must, discard the batch immediately.

IT IS NOT GOOD FOR CONSUMING PLS DONT .

A Black Globe Temperature (GT) thermometer is a black copper ball with dry bulb inside that measures the intensity of radiant energy to give a temperature that reflects not just how warm it is but how warm it feels. The effect of radiation is important under all temperature conditions as excess radiation always increases the heat load on an animal.

i read in many places it is lead or this black copper ball so it hink there is no harm just filter properly the wine then consume.

The thermometer may contain volatile chemicals, but what about the glass surrounding the thermometer? The thermometer itself didn't break just the black stuff at the bottom. Do you know what that is made of?

some are lead shot others bismuth for food thermometers they distribute the heat evenly from the glass media to the bulb.

Umm that's not a thermometer. It's a Hydrometer. And the Little black balls are just weights. Usually made out of steel or iron. A hydrometer floats in the beer and based on how much of the top sticks out tells you the approximate amount of alcohol in your beer.

That's a thermometer. You can clearly see the mercury tube and the Fahrenheit scale on one side and the Celsius on the other.
