Specific Gravity - The Home Geologist

Join me in a new series where we'll go through all the ways you can bring Geology into your home! In this first episode, we'll talk about specific gravity.

I really like that you left in the parts that didn’t work out, we can learn so much from that as well. Thanks for making such an easily understandable video.

[@SarahBurnsStudio]

Omg I’m going to learn so much in this series!

Somewhere floating around you can find a theoretical specific gravity accuracy chart which you might find useful as well.
I have a video idea for you if you're brave enough. What is the specific gravity of your orange cat vs the grey cat?

[@DonohueLabs]

I think the addition of all my blood to the water would throw off that calculation!

Super video sir

[@Celestial_Reach]

hey, why do most scales use water thats not weighted on the scale?

[@user-ie1tz5rm8x]

Old school...weight of dry rock ÷ the Volume... specific gravity a measure of absolute density....the water is to measure the volume ...( How much air is displaced)....i think the specific gravity of water =. One...1...so it's assumed .

[@ChandreyeeJohnson]

What if the specific gravity is .05 higher than the specific gravity of a stone? eg, blue topaz per GIA is 3.53, in general, I'm seeing online that says 3.5 to 3.57. Mine is pulling up around 3.58. Any advice or info would be appreciated

[@DonohueLabs]

The range is more correct. Looks like GIA reported a single SI value for...simplicity? So your measurement is just 0.01 higher, which for home units is really within uncertainty I think (I give mine plus or minus 0.03).
