Cutting glass
If you are trying to cut your own glass and this is your first time use some kind of oil on your glass cutter. Do not cut glass with a dry glass cutter you might waste your glass. I dip my glass cutter in motor oil but any kind works. Also it only takes one cut or pass with your cutter from one end to the other to make a cut. Dont let your straight edge move, make your cut ,then break.
