No wonder I always got detention for daydreaming
Geez: This question came up at WetDreams the other day. Briefly, this was my response
Depending on what is trying to be accomplished, hygroscopic amounts of h2o can bee a good thing in tone. Whether washing or re-xtalling pfed or meth.
But more so with meth.
The Tone alone(dry) is great at removing excess acidity, but for purification purposes aside from re-xtalling along with alky, it removes little else when dry.
This is ware the hygroscopic amount of h2o can beecum an aid at dissolving and removing some water soluble impurities.
Granted...wet tone will pull goodz, but consider it another step toward purity and a rainy day surprise container, as you pointed out above.
A rewash with straight tone after evapping the trash/goodz will yield the rest of the xtals while carrying away just the trash impurities. Ibee's grown some huge shards sitting in backwash for a week or two.
But for purification purposes, when it's thought of in that light, it's easy to see the benefits of h2o's trash pulling properties against the alternative side of using just Dry Tone.
Dry tone, pulling only what is soluble in it!
Yes it may be considered just a matter of preference in the long run. A full blown rextalling versus WetTone Washing runs close to neck and neck, IMHO.
The deciding factor will always be how much work one is willing to employ is search of purity.
Just a few considerations from another school of thought!
At Ibee HIGH School, The Kidz enjoy letting the scrubbers scrub while they are out playing at recesstime! Or "Out to Lunch" may be a more accurate description!
