Radium Girl using lip-dip-paint technique, “The Radium Girls: Kate Moore.” 

The women were even encouraged to rub the paint brushes between their lips to make them pointy and speed up the process. This was called the lip, dip, paint technique. Sometimes, the women would even paint their teeth, bodies, and clothes with the paint to make themselves glow. 

“The radium paint was mixed in small saucers. Using a camel's hair brush, you have to have a fine point and practically all the girls had the habit of wetting the brush with their tongues and lips. That's the way this terrible, terrible poison got into our systems. We never even knew it was harmful.”
