Little tip, stoves are hot plates!! I once though about buying a ceramic plate to put on my stove to make a rigged up hot plate. Also purchase a thermometer of some sort to monitor the temp and you have a “hot plate”
I would just becareful about getting water in your material. Concentrates tend to absorb moisture.
I always worry about moisture. I keep it at a low water level, and barely even touch it.
Mostly use distillate n stuff so i heat it that way, and use for edibles mostly, so if water gets in my edible distillate I don’t freak out as I would if it got into vaping distillate or vaping/smoking concentrates
a Pyrex I’m afraid that there could be chipping happening while the tool makes contact with the glass and that would end up in our concentrates
I’ve found etching glass to be pretty tough with dab tools. I experimented with scoring glass for crystallization, and found I needed something with a greater hardness to really scratch up the glass.
That said, glass will not be inhaled, chemicals that are leached will be. I can tell you which one I like the idea of less.
Also, more bluntly, I don’t think glass scratching is an issue for any commerical producer using pyrex pans for whipping.
All the extracts we make are ethanol based. I have been able to make shatter, budder, crumble, and even sauce with ethanol extract.
Honestly once you get the solvent below a certain percent it brings out a totally different smell. We are required by the state to have everything below 5000 ppm or 0.5% so once you go that low you can’t even smell the ethanol. Our extracts typically hover around the 2k ppm mark. Ethanol based extracts do smell quite different than any -tane extracts and I believe that’s because the ethanol is able to extract different terps? Or maybe the co-evaporation of specific terps only leave behind very specific terps in more abundance. All our extracts do have their own specific smells due to the ratios that these terps already exist in the plant.
I have read about esters, aldehydes, and ketones that can cause the plant to give off even more specific smells so maybe ethanol isn’t as good at keeping those around but any -tane is better? It’s been a while since I read up on that stuff so maybe someone else can weigh in better than me.
Well my friend you have given me a lot to think about now and I will start trying to implement more PTFE in our lab as a serious change! I wonder if I could find some PTFE trays for whipping in instead of using a liner on Pyrex? Have you ever seen such a thing?
Either way I really appreciate your input and I hope others read this and find great use from it as well in their cannabis adventures.
Also I know that leeching is a terrible thing at any capacity but I would assume that the relative amounts of these terps would have greater impact on the amount leeched. For example if you dumped 50 grams of D limonene into a silicone tray it would leech much more and much faster than the small amount found in my extract. And if I only used it to whip and dry then transferred to another glass tray with PTFE after it would minimize to amount of time said solvents were in contact with the silicone.
Instead of trying to reduce time why not simply avoid it altogether? As mentioned above it is prefectly safe to whip in glass. You don’t need to reinvent the wheel.
But PTFE only really beaks down under high heat if I’m not mistaken. Google says 350 C. Solvents don’t have the ability to break it down so that flourine should be locked up nice and tight.
I’m trying to think of ways to make a PTFE dish for whipping in. Do you have any ideas? @CuriousChemist22 care to brain storm for fun?
I was thinking some type of metal ring around the top and a silicone bottom lined on either side with PTFE somehow.
Here’s one of the first google results for PTFE bowl. I’m sure a good long exploration of the Google rabbit hole could come up with what you’re looking for.
