drawing and needle size- a must read!

[THeMaCHinE]

I just take a pyrex glass measuring cup, put about an inch of water in it; microwave the water until it is boiling (about 3 mins); I take it out of the mic, wait till it stops boiling and set the vial in. Prior to putting the vial in, I pierce it with an 18 ga needle (and leave the needle in ((no barrel))) to relieve pressure in the vial as it heats, occasionally swirling the amp. The crystals will dissolve after a little while.
