No. The typical snooker cue tips are much smaller than the typical pool cue tips. So, you can fit a pool cue tip to a snooker cue, but not a snooker cue tip on a pool cue.
It is called chalking the cue. The pool chalk is an abrasive, not chalk, and provides more frictin between the cue ball and the cue tip.
No. Other than both being cue sports, they are very different.
Yes, and most people do so. However, if your cue has a medium or soft tip, as many cues do, this cushions the contact with the cue ball, and lowering the force of the break. In addition, it will lower the lifespan of the cue tip drastically. The advantage of using a dedicated break cue is to be able to use a very hard tip to get as much energy into the break as possible.
A pad, known as a cue tip, is glued to the narrow end (tip) of the cue. A small block of cue chalk is rubbed on the pad to prevent the cue tip sliding off the billiard/snooker/pool balls.
Leather is used for the cue tip, and pool chalk is used to provide more friction against the cue ball. Pool chalk is an abrasive using materials found in sandpaper. It is not a form of chalk.
Any material can be used as a ferrule on a pool cue, but not all materials can be used for the tip. G10 is a type of fiberglass and is the hardest that can be used for both the ferrule and the tip. There are also cues that have stainless steel or brass ferrules, but these cannot be used as the tip material.
That is a typical snooker cue.
This sounds lke a snooker cue. It is not a pool cue. Riley was not a recognized cue manufacturer in the US as either a production or custom maker in 1956. This cue has little value in the US to a collector and no value to a pool player. It may have value to a snooker player.
The best tip depends upon the player skill and type of play. If the tip is 14mm there is no reason to go softer than a medium tip. Using a soft tip for additional cue ball control should be limited to a tip of 13mm or smaller. A hard tip must be used for a break cue, but will take away from control for normal play. A hard tip is often used on house cues simply so it lasts longer. The brand of cue tip becomes a preference based on play that is a result of many thousands of hours of playing pool. The brand is unimportant to the average player - the hardness, curvature, and condition are important.
Although playability can be in part a personal opinion on the "feel" of the cue, it must be straight, have a proper and well shaped tip, be properly balanced and the shaft must be clean and smooth.
The tip of the cue is provided with a multi-layered leather tip on its end that allows better contact with the cue ball. Without a properly maintained cue tip, a player cannot have proper cue ball control, one of the most important features of the game.
