Clean the glass. Clean it a second time. Drizzle a line of kerosene
on the line. Score. The scoring should sound like a continuous
ripping. Put the score on the edge of a table and give it a quick
snap. You could tap the glass along the score line if the glass is
thick. I have not ever tried scoring both sides--don't need to.
Always, protect your eyes.

Wondered if someone would mention liquid. We always wet the score
afterward with water, spit will do. Never heard of using kerosene. Most
what I did was with glass tubing in the lab and it was unnecessary to
score all around the tubing as water helped propagate the crack. With
glass sheet you probably should score all the way - only one side. You
break by pushing away from the crack. The crack will propagate to the
other side. To avoid a sharp surface on cut glass in the lab, we would
sand down with metal screen. A couple of quick passes would dull the cut
glass.

I have read instructions to dip cutter in kerosene .. have tried it, but
noticed no difference. I have never seen instructions that advise
cutting both sides, but it certainly makes sense for laminated glass.

The kerosene works as a lubricant and coolant.
