Spots burned by heat?

[taipafan]

We know those spots at the clothes, will demange after using for a period of time.
Is it happened because the pressure or impact when we put the colors on them? Or because the heat produced when a ball is hit?

I don't think it's because of heat. More to do with players banging the balls on the spots.

【4. Less marks on cloth and balls
Resists at the instant friction temperature of 482?F/ 250?C when the ball slips into motion. No abrasion or flat spots on the ball that accumulate dirt and wear the cloth !】

Yes, banging the balls is the main reason, for most of the tables.
But what ratio of demage from banging the balls and the heat?
50/50? 90/10? 99/1?

How about a table that only putting balls to the spots by referee, by first putting a ball beside the spot and then roll it to the spot?

banging ball to heat - 100:0
as mentioned above heat is a negligible factor

placing ball to the side and rolling to the spot will definitely increase the life of spots and cloth

It's because the colour is contacted on and moves from the same place many hundreds of times, where the ball lay will first leave a mark, then the nap will go and then that mark will degenerate into a dip in the cloth. Also there will be a ring of chalk around the spot, that eventually goes under the cloth and hardens where the said chalk has come off the cue ball on contact with the colour. When re-clothing a table this chalk ring, though very small, needs to be removed, or it will get worse and the cue ball will leave the bed as it moves over it, thus striking the colour above the horizontal centre, causing a bad contact and making the dip in the spot worse.
Don't be fooled by that Aramith advertising spin, their phenolic resin material is crap, otherwise there wouldn't be different grades of balls.
