could be that the water dissolved the lime but it crashed out later? That would be pretty cool.downwardsfromzero said:We need more detail before any comment can be made on this.slewb said:I've noticed this happening in a couple of extractions so now I'm doing an experiment. There's this white precipitate that forms at the bottom of an IPA pull if you leave it in an uncovered jar for a few days (photo attached). Any idea what it is? Possibly lime? Once I'm sure it's finished coming out of the solution, which I think it almost is, I'll decant the alcohol and add some distilled water to see if it dissolves.
*What did you extract from?
*What base was used?
*What other steps were there in the extraction before the IPA extract was obtained?
*What percentage purity is your IPA - is it anhydrous?
By 'lime' are you sure you mean calcium hydroxide? Calcium hydroxide is only slightly soluble in water and insoluble in isopropanol.
I am about to try this one too but thought about using lime instead of sodium carb. I have both though. I loved the q21q21. This tek will be awesome though because I am aiming to make a non-toxic start to finish Changa.
