I use a fine mesh in my cone-piece. It stops that 'pull-through' effect where you lose some of the weed into the bong (billy over here in Oz). After each cone, I have a special 'ashtray' where I dump the ash. There is usually a very small amount of unburnt weed from the outside edges of the mesh, so if I run out, I can filter the ash through a tea strainer and collect all that unburnt weed. I can usually salvage a dozen or so cones from every half ounce smoked. But, seeing as I rarely have to wait for weed (I have a very consistent supplier), I rarely have to resort to the ash bowl. We did have a time where we had to wait for two days for weed and the ash bowl hadn't been filtered for quite a while. Ended up not having to smoke all of the filtered stuff. There was heaps there.
I used to get quite a bit of resin from my old mull bowl, but the one we have now doesn't seem to collect resin...and I wouldn't scrape my stem for love or money.
Speaking of cleaning, try using Tea Tree oil to clean the shit from your stem and cone-piece. Just make sure you rinse it really well afterwards, else you'll have the taste in it for a few days after. |
