Score

Scores are how glass is broken down into smaller parts, made with a Scoring Tool on the surface of the glass. Often done on the flattest and smoothest side of the glass. Scoring glass is not like cutting, sawing or abrading. Though many people call the act of scoring glass "Cutting Glass" there is no cutting being done.

How scores work

Scores are nothing more than an intentional scratch put into the glass that creates a weak point for the glass to break at. Though this won't stop the glass from breaking in other areas or directions because the Run will still follow the path of LEAST resistance. All glass will contain an invisible stress matrix that dictates where a break actually ends up.

Once a score is made on the glass it can't be undone and the glass will eventually break at this point regardless. Thus it's best practice to always break any scores that are made.

Scoring glass takes a moderate amount of pressure to get a correctly formed score. This means that there is a such thing as too little pressure and too much pressure. Too little and the score will not form or create a weak enough sport for the glass to actually break at. Too much and the score will be rough, chip out and sound like there's sand in the score. Going even further can lead to the glass snapping below the tool.

Glass can vary in hardness from one type to another or even from batch to batch thus what works well for one sheet of glass may not work the same for other sheets of glass. Scoring glass reliably is a big feedback loop with constant adjusting.

When scoring you want to do one consistent score from side to side, scores can't stop mid way in a sheet unless another score will pass by it. Stopping too far away from the edge or another score will allow the Run to decide where it will go on it's own.

Scores can make various sounds or even be silent depending on the glass itself. Often times people will say to listen for a sound like a zipper being zipped for what a good score sounds like. Sand noises means too much pressure and no noise means the glass isn't being scored or just doesn't make any when scored.

A good score should leave behind a small divot in the glass, this diviot can be felt when picked at with a fingernail or similar methods. If nothing can be felt then a score was not sufficiently made.
