There are several instances where one whom is in possesion of a multi-piece Grinder has an oppertunity to indulge in lovely session of kief only. The same applies to the ever so prominant methodology of Vaporization. And thanks to the Internet and the application technology, most of us have access to purchasing many several Vaporizer models. Alot of these models however, do not accomodate a user who is wanting to partake in the use of kief, and kief only. Being a fairly powdery substance, it is highly likly that much of the product is going to slip through the cracks of a screen. this forces the user to mix bud with the kief, if one wanted to vaporize it. Well, the fact is, you do not have to. What I am about to explain is plainly "oil bedding". For my example I will be using a Direct Draw model with whip, akin to the Vapor Brothers, or Silver Surfer as the example. What is needed, and is the most important and only piece of material you will have to buy, is a fine and flexible, tiny micron screen. I use the screen from a Vapir O2, that is used to filter the mouth piece. I would start by bending the screen so it resembles a container. Then slip that screen into the wand. I would only put it in there slightly below the surface opening. Bare in mind that your original screen is still intact and inside the wand. There is no need to input/remove it as it does not hinder the process. Simply, one would pour the powdered kief into the wand with small micron screen being used as a cup like container, and proceed to vaporize it. You will notice a very thick and consistant vapor quickly emitted, without the need to get a piece of bud going. Later, you can slip the screen out, and wont have to worry about powdered material clogging up your main screen. I started doing this mainly because when I want hash, I only want hash. There is a reason for that, and the reason is I like the effect of hash alone, without that of the bud. And visa versa, as they both convey slightly different effects.
