Ok so after a few attempts using Vovins tek, one wants to expand their horizons and try new things.. Specifically q21's lime/vinegar tek... but as anyone in Canada probably already knows, lye seems to be much easier then lime to come by...

Anyways after much reading on here it turns out pickling lime is non existent in Canada and one must find an alternative source. In another thread someone said (I believe it was Q21) they get their hydrated lime from Home Hardware... However the only hydrated lime available there seems to have silica (0.5 - 1.5%)

What I really want to know is, will the silica in this product be soluble in the NP solvent (in my case naphtha), thus contaminating the final product?

Full product details can be found here
And the Msds can be found here

Sorry, the links apparently don't work, check the last post for URLs that should work...

Sister hasn't read the tek you are following , however the crystaline silica is like sand, it will drop out of solution and sit on the bottom of your beaker. From which your solution can be decanted.

If memory serves silica also acts as a weak lewis acid so it may lower the ph a tad, but aside from that there should be no reaction.

Hey, sorry, just realized the links weren't working right and that might be whats limiting the responses...

I guess what I'm really asking is there a chance some of the silica would dissolve in the naphtha, thus contaminating the final product?
And if so how would one know?
And if so, is there anyway to prevent this? Or should one simply look for an alternative product (although walmart, home depot, rona, and canadian tire have all been tried unsuccessfully)

Bump...I hate to do this but does anyone know?

I've done some reading and apparently it is polar and thus shouldnt dissolve in naphtha but im not really up on my science ...

Any help would be appreciated
(PS I'm in Canada and apparently Ms Wages doesn't ship here, or am I wrong?)

silica will not dissolve in naptha; it will dissolve in high pH solutions.

so then for a dry tek (as q21's) it shouldnt be a problem, as its not really in solution, should it?

lye is hygroscopic, as is silica.
the silica will gradually be degraded in the presence of lye

but with q21's tek one doesnt use lye, lime is used instead because it is a "dry tek" and from what i understand lye doesnt work (ive read it some where but i cant remember why right now) but thats beside the point lol...

the lime in question contains .05-1.5% silica and i was wondering if this silica would cause a problem...

would lime gradually degraded the silica like lye would (although this tek, q21's, is a dry tek)?

and if so what does it degrade to? and what does this mean for the final product? does it means some degraded silica would be carried over during naphtha pulls? and if so is there anyway to tell?

sorry for all the questions but i just want to be sure this wont cause a problem before this new tek (new to me) is attempted

thanks for all the help so far, much appreciated!

there is a thread in science by tangarine dream that tells u how to make hydrated lime from the pet store. also i believe u can almost always use sodium carbonate which is just baked baking soda. correct me if im wrong on that bit i know with bufo u can use it interchangeably.

ive tried the pet stores and no place here seems to carry kalkwasser or i cant seem to find it atleast... lol

home hardware (i live in canada) seems to be the only place around the area with lime but as stated it contains a very small percentage of silica

i've seen posts questioning whether the use of sodium carbonate in place of lime for q21's dry tek would work but havent seen any updates... if it would work could someone please let me know as that would be great.. like you said its easily made but besides that ive got more than enough already lol that has been used successfully to wash before freeze precip on previous a/b teks

but as for bufo ive got no idea... havent dabbled there... yet lol
