Nail

 Share 

A metal device which looks like a nail with a very thick head, they are normally made of grade 2 titanium, quartz, or ceramic, but cheaper versions can also be made from borosilicate glass. This is the part of the rig which is headed with a torch and then has the concentrate dropped onto it, causing the vaporization process to take place. When heating a nail, it is best to get it right to red hot and then let it cool for a few seconds prior to dabbing, as this makes the smoke a little easier on the throat as well as preserves terpene.
