Extraction Fail

[Hickey]

Hello Nexus members,

I was performing the A/B extraction for my fourth or fifth time. I decided to be more patient this time and allowed my sample (~60g MHRB-worth) to sit for over a week to ensure a quality yield. Unfortunately, I heated my water bath too high for my pull (I guess) as the glass container cracked and all of my sample leaked and diffused into my (~1 gallon) water bath. I tried to do my best to decant the water immediately and save the sample but it seems to be completely compromised.

In any case, I saved what I could and incubated the pull at -20C to see if I miraculously got anything - I did not (following 48 hour incubation). The remaining sample is split into one lower level of mud, followed by a distinct middle level of water with mud-bubbles, and a top level of very small naphtha volume that I cannot seem to obtain with the samples loose-consistency.

Is there anyway to save this extract?

Since boiling off such extremely alkaline water is a no-no, the simplest way to salvage this would be split up the total volume of water into smaller, more manageable containers, add enough base to each to restore the correct PH and pull from those with lots of solvent. You'll have to evaporate quite a lot of solvent before precipitation.

Another would be to simply add more bark and more base to these, and continue as if it was multiple STB extractions.

So the vessel cracked eh... that's the problem with overheating the water bath... I should probably add that to my own tek actually.

As always, throw away nothing until the extraction is finished.

Great advice thank you

I believe that's the problem with glass I always use HDP jugs for all my stuff now after an unfortunate accident.
Cleaning glass shrapnel and basic solution spraying everywhere in kitchen was kiiiiinda a nightmare O_O

Mason jars are made for canning. If you're going to be adding a hot liquid to a canning jar, follow these directions:

Jar Preparation
Fill the canner with water and place the jars in the rack. Cover and bring to a simmer over medium heat. Reduce heat and keep jars hot until you're ready to fill them.

Essentially, you need something sitting at the bottom of the pot so the jars dont touch the bottom. The water level needs to be near the top of the jars so that the jar is near completely submerged. Typically in canning/preserving people use a canning rack. A metal vegetable steamer works well. Then bring the jars to a medium boil.

Be careful not to burn yourself on the jars.

Canning jars are Soda-lime-silica glass, and have a high coefficient of thermal expansion. They expand or contract "a lot" based on the direction of the change in temperature. So by heating up jars in a medium heat bath, you're allowing the expansion of the jar to happen slowly. When it happens too quickly or unevenly around the jar, the glass is expanding too quickly or too localized.

Pyrex is made out of Sodium Borosilicate. It has a very low coefficient of thermal expansion. Therefor, they contract/expand "very little" with a change in temperature.

Hope this helps!

All helpful responses -- thank you

What Orion said ^

I fell victim today; in contracting cracked jar syndrome too. (Boooo) :thumb_dow
Fortunately it cracked whilst in the freezer, and my mixture survived!
(Although it may have been a result of my heavy handed partner routing through for food..)

Henceforth, I will slowly pre-heat/cool my glassware. Sloooooowly! And use a buffer for the heat. Ie- A 4x folded peice of A4 paper in the pan, and allow room temp to be reached before using the freezer!
(And boobytrap said freezer to keep badgers out!)
