Some pics from last night and today
Spoiled myself and bought a stainless blow tube with a rubber stopper. I put 2 coffee filters first and then the mesh with a hose clamp
Blew onto pyrex heated to 100 degrees f, let dissolve until most big bubbles stopped.
Transferred to chamber heated to 90-110 degrees and been at -30hg for 24 hours. Gonna do 12 hours, flip, and repeat for 3 days
Pic is after 12 hours , already pretty stable
