90% Calcium Hydroxide?

[kinderfeld]

Hi all!

So I'm getting materials ready for Q21Q21's Vinegar/Lime A/B Extraction Tek and was wondering if this was suitable to use...

High Calcium Hydrated lime.

The MSDS is as follows:
calcium Hydroxide:...........>90%
Magnesium Hydroxide:.......<5%
Magnesium Oxide:............<5%
Calcium Carbonate:..........%
Crystalline Silica:...........<2%

will these extra ingredients screw up my extraction? Pure Lye has been almost impossible to find as well as pure Pickling Lime. Any input would be greatly appreciated!

I wouldn't use anything unless it was pure.

You can find pure KOH in solution @ hydroponic stores as Advanced Nutrients pH up.

Thanks man . Picked up some A.N. ph up and the MSDS says its 45% KOH. Doesn't say anything about the other 55% however. Could this be water?
