Those numbers could be if packed to gypsums absolute limit. It's this variance that makes volume practically useless.

It seems like concluding there are fillers is kind of a stretch.

It was a sarcastic conclusion!  Fun!  Weee!!  Yayyyy!  Wow!!! Yipppeeee!!! Yahooo!!!

When did home-brewing become a serious endeavor?

Since they started handing out medals!

You want a medal for that?

I agree with ya...if homebrewing isn't about fun, YDIW!

You, sir, are on the verge of discovering the biggest fraud in homebrew history and you don't care?

History is in the making!

According to this:

https://www.usg.com/content/dam/USG_Marketing_Communications/united_states/product_promotional_materials/finished_assets/calcium-sulfate-filler-brochure-en-IG172.pdf

The math works out to (Calcium Sulfate Dihydrate):

3.32 g per teaspoon loose
5.5 g per teaspoon compacted

Which is about 97% pure.

Is the gypsum discrepancy coming from the difference between crystalline and powdered forms? Anhydrous vs dihydrate?

The math for calcium sulfate anhydrous works out to:

3.5 g per teaspoon loose
6.3 g per teaspoon compacted

The specific gravities listed are 2.32 and 2.96 (dihydrate and anhydrous)

If you take the solid form and do the math you get the specific gravities listed.

So 11.4 g / tsp would be for calcium dihydrate in a solid state.

When 'Steve in Tx' compacted and weighed his teaspoon of calcium sulfate he got exactly what he should have.
