OK it's late so I'll be short since I actually have to prep a client for year end tomorrow... At least I get to help spend some money even if it's not mine =)
Basically chalk is made up of 3 parts... Binder, Fillers and Abrasives.....
Binders have one purpose... Hold the friggin chalk together... Clay has been used for years and will continue to be...
Fillers... For years fillers were just to make up volume but recently they have found out that using certain fillers will make the chalk go on smoother...
No offense intended but this is not a recent discovery.
ie Kamui... Some fillers can also help bind the chalk when it's pressed... Fillers have a lot to do with the chalks feel but not with how it works....
Abrasives... This is where the rubber hits the road... This is also where the premium chalk can excel if their QC is right... With a cube of masters there is no real standardized abrasive size..
Not true. The abrasives are selected specifically by size, shape and hardness. Microscopes have been around for quite a while.
Abrasives are measured in microns.. Too small they don't bite and too large your chalk feels gritty...
If you look at the surface of masters magnified you can see that there is not a consistency to the abrasives across the surface...
Perhaps what you mean is, there are multiple sized particles. This is true, by design, not negligence.
Different micron sizes and some ares that are nothing but filler...
Thats an awefully big claim without any actual proof. Could you provide pictures please?
If you put only filler on your tip you will be very surpised when you misscue after chalking... And if you say it's never happened I'd have to call BS...
On a premium chalk like Blue Diamond you will see a better distribution of abrasives there will be no filler only areas but some areas will be weak because the micron sizes vary... Small micron sizes don't do much more than filler so if you hit a patch of that stuff you might get a sliding feeling from your tip instead of a full misscue....
Kamui is 30 bucks because of the purity and consistency of the minerals they use... And because of the QC they put into making the chalk... Kamui under magnification is consistent in distribution and micron size.. If you misscue with Kamui it's ALL on your stroke.. It's not because you didn't get what you thought you paid for....
Now with that said as long as your tip is porous and doesn't glaze over for the most part the leather lets the abrasives set into the face of the tip... Most of the abrasives used are ruptile...
I wouldnt say "most".
Some of the most used and most popular silicates are nearly as hard as diamonds and do not break down.
which means that they fracture ad create new biting surfaces under pressure.. This means that you can likely shoot several shots before you run out of chalk.. Or what it really means is that you can rupture the abrasives several times before they are too small to create a bite... That's why Kamui can last a game or longer... You start with large micron sizes so as you break it down it keeps on biting....
If what you are claiming is factual, it means that the performance of the chalk would change the longer it has been on your tip.
OK that's longer than I intended but I'm a pool nerd and Outsville is working on chalk hopefully by Tunica... It's not gonna be $30 a cube but it's not going to be $2 bucks a cube either... Man I have toooooo many projects.. Tips and a COR tester will be out around Derby and I hope to enlist AZ's help on evaluations....

I've mentioned this before - I think some of you should just perform your own "grit" tests at home, or else you'll never be satisfied.
(as far as old formulas working better than new. and this chalk is grittier than that one etc.)
Create an inclined plane. (a piece of wood or metal set up like a ramp)
Create a sled. (a piece of wood or metal to slide down the ramp)
Apply various chalks to the ramp or to the sled and measure the differences in their sliding charactersistics.
Sounds cheesy but they do it just like that in the lab.
According to Mr. Renfro, you might want to beat the chalk up a little bit too. (to break down the particles)
