Default white/clear pin wheels ?

Friend just made white/clear pin wheels and wants to know if he's done right? Or ???

the white in the pinwheels is gakk. it has been SWIM`s experience that the pinwheels are translucent. not clear but certainly no white in them. it shouldnt turn white untill you scrape it up. even when it all looks translucent hold the evap plate up to a bright lite. see the small scattered flecks of white grit?

Okay,...pardon my friends french, but it looked like someone shot their load in the pot.......two days ago!

But he did throw it in with dh2o placed in freezer for 1/2 hr, filtered and noticed the differnce. Therefore convinced that is clean .997 fine psuedo.

Now with the 3 ingredients- he doesn't know what to do?

Read the thread entilted Here they are, 3 steps...or something along those lines. Lovingly written by our very own....rainman. Who took a long while in translating all the scientific jargon into terms we could all understand. It's not very old at all, in fact if I find it...I'll give it bump. It's well worth it.
