What I'm looking for is, does chalk stay the same from room to room all over the world, does it stay consistant in all temperatures, or will chalk work better in cooler temperatures, does humidity affect chalk at all...should you only play with one pice of chalk all nite long or doesn't matter..
Is Master chalk the best or what do you prefer?
Is there any other posts on Chalk?
Thanks
