Any good NAOH alternatives?

[StatuesCryBleeding]

I've recently started to invest the time and energy into extracting spice for my first journey. I've ordered bark from a quality vendor. As I await it's arrival, I've decided to make the best of this time, and to start gathering ingredients. After a little shopping, I've found everything I need except for a quality source of lye. Can anyone recommend the best, readily available alternative? I have plenty of pool ph+ (sodium carbonate?) laying around.

I plan on using a STB tek, and perhaps freeze precipitate.

I've heard that to move actives from bark to naptha lye is necessary, but if you are using another more polar solvent a relatively weaker base may work.

Trisodium phosphate got my attention recently, I wonder if it would work better than lime in some situations? It's strong enough to hydrolyze oils...
