New gels soon…

I’ve cleaned the workspace enough to set up another triple batch.


Open door, or turn on exhaust fan to ventilate (30% Aqueous Ammonia is Fragrant, to say the least).

  • 50ml TEOS –> 150ml
  • 40ml Ethyl, 199.9 Proof –> 120ml

Place in 500ml Pyrex w/spinner on Mixer #1, labeled “Fast”. Place cover on Pyrex.

  • 70ml Distilled H²O –> 210ml
  • 2.42ml .5 Molar Ammonia Fluoride (twice listed amount) –> 7.26ml
  • .275ml 30% Aqueous Ammonia –> .825
  • 35 ml Ethyl, 199.9 Proof –> 105ml

Place in 500ml Pyrex w/spinner on Mixer #2 labeled “Faster”. Cover Pyrex and wait for 5 minutes.

Remove Pyrex with Ammonia-Ethyl-Water mix. Transfer TEOS-Ethyl Mix to “Faster” Mixer. Uncover A-E-W Pyrex, remove Spinner (Magnet & Nail outside Pyrex…) , uncover TEOS-E Pyrex, and slowly add A-E-W mix to spinning Mixture. Cover & Wait 5 Min.

Place molds on flat, clean workspace.  Remove Pyrex from Mixer, Uncover Pyrex, Remove Spinner #2 with approved method (above), pour PreGel into the molds, a little at a time, and when full, cover for 24 hours.

Hey, Y'all, I've been rather ill recently, and that has kinda deprived me of the ability to post regularly. I may or may not ever post regularly again. Thank you for playing.
