Go from room temperature, fridge and then freezer overnight. Then pour off naphtha from glass dish through a coffee filter to catch any goodies. Place glass dish upside down at first, prop up one end and place a slow fan on it while it is upside down. When you see all the naphtha is evaporated you can turn dish right side up and allow to fully dry before scraping with razor blade.
If you feel like you have followed all the steps properly and still are coming up with low or no yield you may have a bunk or poor quality MHRB.
Sweet! I'll try that out next. How much do you usually produce off of 100g mhrb?Go from room temperature, fridge and then freezer overnight.

Nps being naptha? And thanks for the help and words of encouragement.. I'm cool with losing some bark to learn and get better and better as I go. Hopefully, there will be no waste on the next oneMake sure that you save your naptha. You can reuse naptha quite a bit and also you can pour your naptha back into your base soup jug for each pull to really get the most out of your bark because any dmt that you didn't manage to get to stick to the glass can go back into the base soup jug and will remelt along with the next pull. Keep doing this till you don't see anymore dmt and your bark is pretty much spent at this point.
When mixing in your NPS you also want to make sure you are thoroughly mixing your naptha with the soup before taking your pull. Want to rotate your jug from top to bottom like pedaling a bike slowly then allow layers to separate and repeat this process 4-5 times over the course of an hour or so. If your ratios are good you should see your layers separate pretty fast.
You also want to make sure you aren't using too much NPS. The precipitation is caused by over saturation of dmt in your nps. The nps can hold a lot more dmt at room temperature or slightly heated then when it is cooled down so as it cools it begins to "crash out' forming your crystals. The slower this is done the better, more dense your crystals will form. I like to use thin neck vessels for this reason like an erlemmeyer flask. I generally will only use between 50ml-75ml for an extraction of 100g of mhrb with about 900ml of water.
If you're still having issues it could just be super low yielding bark but I have confidence there is a work around. My very first extraction I didn't see anything crash out my first pull and was confused because the bark I get is great, once I realized I didn't mix my soup well enough or let it sit long enough and mix it more then I got a fat first yield. Sometimes it just takes a little messing around with. Don't lose hope!
Good luck and safe travels!

I think I got it! White stuff at the bottom is the final product?Forgot to add you can also evaporate some of your NPS before covering to help with saturation. You can tell when you have reached good saturation because youll see cloudy whisps in the naptha. Make sure you only cover with foil do not use plastic or syran wrap. I like to use foil then place a snap lid cover over the top so none of the NPS leaks out into the freezer and also so water doesn't get into your extraction.
