Basic Glass Cutting

This is part three of a multi-part series on glass cutting.  Click here to go to part one.  

Continuing our list of important factors to consider when cutting glass....

-- Use the right amount of pressure. You should hear the cutter scratch the surface of the glass. If no mark is left behind, then you're not pressing hard enough.  If you see flaking slivers on the score line, then you are pressing too hard.

-- Cutting at the right angle. Don't let the cutter drift to the right or left. If the cutting wheel is tilted, you won't be able to get a good score. 

-- Only cutting once. Never correct a mistake by cutting again. Never go over the scored line a second time. Not only will it fail to cut the glass, it also can dull your cutter. If you have to, turn the glass over and cut on the other side. If that doesn't work, then use a grinder to grind the glass into shape.  

-- Just a touch of lubricant. Some people cut without oil, others lubricate their cutters generously. For fusing, the best amount of oil to use is the least amount you can use and still keep the wheel from freezing up. Excess oil means more time cleaning the glass before fusing.
