I've heard people say that chalk absorbs moisture over time. I've also heard people say that it dries out over time. Maybe it just depends on things like where the chalk was stored or how it was made. Comments?
It is CHALK!! The same stuff your kids write on the sidewalk with.
Of course it absorbs water if available and dries out in a dry environment.
Perhaps someone can get a gov't. grant for a bazillion dollars to research another obvious fact.
pool chalk is not the same thing as kids chalk board chalk. why don't you tell us what else you don't know.
Perhaps you posted this thread before reading this post on your last thread by Hu
But my forum name is not named after CHALK. Perhaps you could tell us what YOU KNOW about chalk??

when a plant takes up water via its roots, the plant actually has no control over this (osmotic) process. the water is naturally drawn from an area of lesser salts to an area of more salts, thru the (root) cell wall.
in a way, the same applies to blocks of 'chalk'*
if the chemical composition is such that it will naturally 'conduct' moisture, then it will.
if not, then it won't. or, at least it will release water, or 'dry out' quicker.
*this of course applies to 'water' moisture alone and not 'oils' etc.
So then does it depend on the specific ingredients and proportions of a particular company's recipe, or are all chalks pretty much in the same realm?
Most 'chalks' are indeed very similar, so I would fully expect them all to react to moisture very much the same. Not exactly, but pretty darn close.
I read a thread here once that stated corn starch was one ingredient in chalk. I have often wondered what else is in there besides sand, and what they use as a binder. Seems like the moisture absorbed/released would also depend on the hardness.
'hardness' is directly related to porosity and the shape of the particles used in the mix, which is also directly related to moisture content and absorptive capacity...
He probably wouldnt divulge any trade secrets, but if you're curious about what exactly they put in their 'chalk', get ahold of Skip Nemecek at Tweeten and ask him. He's a nice guy.
Nice website for the Chicago Billiard Museum.
Thank You
Is there a physical museum or just the website?
Just the online archive for now. (which is best for easy access to the information) But there are plans in the works for a physical location as well.
I used to live near Chicago. I searched for chalk and I look forward to reading the info. I read somewhere that there is a large supply of clean sand in the Chicago area and that's why most chalk was made in that area at one time. Besides Tweeten there was Kieckhefer and National. And was Brunswick making their own chalk at one time or just hired it out?
I'm not 100% positive but I do believe that Brunswick was producing their own for a time.
thanks for posting

I think it's time to start selling a humidor for chalk.![]()

I just received a bunch of "Pioneer Billiard Chalk" from Ebay. I tried out a cube today. It is hard and does not want to leave chalk dust on the cue tip.
Is there anything I can do to make it softer, or have I just wasted money on cheap chalk? Thanks.
