how do we test for grains of hardness

I don't know but scale watcher does not make the water chemically softer it makes it feel softer the minerals do not stick to you or your pipes etc i am very glad we bought this

High carbon steel with a Rockwell hardness of 57/59, hope it helps. Chef Ryan

The rollers are a hardened steel, this is an incredible Mill and well worth every dime spent on it. I'm doing 50 lb plus runs in minimal time and all grains are milled to my desired settings

Yes, it looks like this grit will polish rocks up to a hardness of 8. keep your rocks the same hardness and they should eventually polish up decently.

I'd does weigh grains. I didn't use it for grains though. I do know it weighs to .001 grams.

There's no markings indicating an exact grit. Its between medium to fine leaning closer to fine though based on comparisons to honers I've used in the past

I would look for balls that are considered "hard" ball pit balls, but even those may not workthese are "soft"

here is a test that can tell you what they are made of http://www.amazon.com/review/R1DUAL4ZTT6CXT

I'm really not sure. All the ones I checked seem hard like cement. It bounces well but surely isn't soft. Have a good weekend.

Not powdery but not *very* coarse either. Can still feel small gritty granules. Just right for everything.

Some hard grains must be ground twice. You can regrind until you get the flour as fine as you wish. On each pass you tighten the adjustment to a level to where you can turn the wheel comfortably.

The inside surface isn't like sandpaper nor is it rough. But, it also isn't like glass. When you fell the inside you can fell the texture/grain. If there is such a thing as grain in granite.

There are several out there. There is one from (tiny gadget) that is 0.4mm with a 9h hardness rating that is equal to the one that is in the bundle pack. And its a great price as well.

I can't speak to "accuracy", as I don't have access to an analytical grade scale to verify the reading on the Gem Pro. But i can speak to repeatability. I put small amount of Red Dot on my scale and it read 2.72 grains. I reweighed the same sample 10 times and got eight readings at 2.72 and two readings at 2.74. I'd say that is pretty darn good. One thing I do is re-tare often, usually before weighing each sample.

Experience has taught me that the directions are more of a guide then a rule Depending on the stones condition and hardness experience will eventually guide you to what works best. I would recommend research online into polishing the type of stones you are working with then follow that guidance.

It doesn't take much to figure out the level of grit the bands contain - just feel them. The coarser ones are just that; hard & coarse. The soft ones are very smooth with not much grit, and the medium band is somewhere in between the other two. Hope this helps.

I have no idea what Rockwell hardness is or why I was asked to rate it. Sorry
