Translucent Arkansas help please

[stone and strop]

I used my wife's professional baking scale, essentially a high grade kitchen scale, to weigh the stone. I couldn't find a tall enough beaker that didn't overweigh the scale. So, I used a digital caliper to measure the stone and calculate the volume as accurately as I could. Then I used the link @stone and strop posted:


That's how I estimated my stone, @ 2.61. I'll look for a container that will work and compare the numbers. Water displacement should be more accurate.

Mine was pretty accurate. I was at 2.78 by measurement and 2.8 in water. The stones were not perfectly rectangular (although close) and that leads to the small discrepancies.

thanks. i used my kitchen scales with a 48oz wide mouth nalgene.

Nice,

Shame my vintage Norton Black trans is boxed so I can't test it. I'd be curious how it stacks up against my NW trans black (currently the densest I've tested)

I liked the Nalgene bottle tip- thanks! I retested the stone after I found a high enough plastic container and it displaced 134 grams of water. I actually used on of our toilet brush holders , after cleaning it out really well of course. I think that means dry weight of 360 grams/134 grams water displaced= 2.68 for specific gravity. I remeasured the stone more carefully with calipers and came out, after averaging four readings per each measurement, and using the online calculator to 2.656. So, like @stone and strop I ended up with not much difference in the estimate.

With these translucent and good blacks I don't think we will see much variation. The few I have tested have such low absorption it's very difficult to get a number. That tells me the stone is pretty much solid. The regular hards, softs and Washita's is where things get a little more interesting.
