Partial evaporation before freeze precip? and optimal quantity?

[hst2586]

hello everyone

couple of questions regarding noman's tek, if you don't mind!

from reading various threads on it, it appears that a mixture of 25ml water and 1g of lye per gram of bark should do the job, followed by 1ml naptha per gram of bark later...it seems there are some people who think less water/less lye is needed, do the ratios above appear ok?

some people also say that partial evaporation is recommended before freeze precipitation, what does this actually entail- leaving the mixture out in the open air for a few hours to evap down?

finally, is there an optimum quantity of naptha that should be used in each jar for the free precip, or is it more or less unimportant?

t.i.a for any answers!

As for the ratio, seems you're going unnecessarily overboard with water. Check the FAQ before posting when you have a question as your answer might be there already (FAQ: How big should the pulls be and how much to pre-evaporate , and FAQ: Which ratio of Mimosa:Lye:water is the best?)


Hope it helps.

As for the amount of naphtha in each jar, that makes no difference, what makes a difference is saturation levels related to how much one should pre-evap, as mentioned in link above

good luck

ah, schoolboy error, always check the faqs! thanks for the links, they answer my questions.

one more thing though, can evaporation be done without a fan by just leaving the mixture exposed to the air, or would it take forever?

evaporation can be done without a fan, yes, it might take a while longer though depending if its cold where you are and if the air is too still.. evaporating next to a window will make it a bit faster for example. Just be careful not having nosy neighbours because it will stink up a bit.
