Hey everyone, I’ve been in the industry for a couple years now. I’ve worked at a startup hemp extraction, distillation, and isolation company and I’m currently at a startup cannabis extraction and distillation company.
I have a big interview Monday with an up-and-coming cannabis startup company. They are specifically looking for someone to do R&D on rosin and rosin vape cartridges for a new line they’re working on.
However, I don’t really have any experience with rosin. I’m very familiar with extraction and distillation. The last batch of cannabis-derived distillate that I made came back testing at 99.5% total cannabinoids.
Could someone provide me with a list of the basics of making rosin? I’ve seen posts regarding drying and/or freeze drying the plant (not sure why), doing an ice cold water wash (not sure why), and then pressing. I’ve also seen a lot of people struggle with adding the rosin to vape cartridges, due to its viscosity and the fact that they want to market their product as “solventless.”
Any information would be really appreciated. I just want to make sure I don’t look like a fool on Monday. Thank you.
getting interviewed in a couple of days and they are expecting me to know the In and outs of the job, I better go online and get people to feed me the knowledge…It’s like hiring a “master grower,” who has been producing bud For less than a year
to lower the viscosity, rosin is typically very thick. the best method i have found for solventless carts is to press the material very low temp on the 1st press giving a more terpy profile. the 2nd press is turned up in temp to pull more of a full spectrum profile the 2nd press gets decarb and then 1st press is re introduced to the 2nd press to help with viscosity and add some flavor. with this method most of the time i am able to add the oil into carts without any addition to change the viscosity
That would certainly be my expectation, and simply decarbing in a jar seems like a great responce.
What I don’t get is why would anyone buy a “viscosity booster” that reduced the viscosity…ok, it does what you want, but the folks who made it are apparently unable to use “boost” or “viscosity” correctly, so I’d be suspect of any claims of the appropriateness or safety of their product.
Maybe don’t apply for jobs you aren’t qualified for? If you don’t understand the basics of rosin and how to make HTE solventless pens, you’re already two notches below the average CONSUMER of cannabis products, whereas a PRODUCER of said products should be at least three steps AHEAD of where you’re at now, in order to do the job they’re interviewing you for.
I know this is an exciting prospect, but JUST MAYBE… stick to what you know.
