This is the original posting for my medicine cabinet. You can see it clearly, here. I have since added a charcoal filter can to the outlet at the top when the plant goes to flower to remove any smell.
For my press, 180-200 degrees F is the perfect temperature for pressing.
I have found no need to invest in an automatic regulator. I set the temperature using a simple AC variac and a $15 hand held infrared probe from Harbor Freight. Once set, it stays there all afternoon.
Goodwill Store is my favorite place to shop. You can find so much there and get great ideas for new projects. I hit two or three of them most every week.
You mention a 12% return in concentrate from your hand press. That's not bad at all. You'd likely increase that if you make a press like...
Assume you are addressing this question to me.
The vapeurextract products all contain PEG, VG and PG to some degree. I found the results to be way to harsh on my throat. After much research, I decided I did not want to be inhaling any of these chemicals so I looked for an alternative. That was...
Isopropyl alcohol is rubbing alcohol, which is poisonous to ingest. Why people continue to use it is beyond me, but they do.
Ethanol at 95% is safe to use. I'd stick with that if I was you.
Stay clear of using any additives with your rosin. It's all garbage and so not necessary.
Why don't you consider growing your own plants, organically? It's not rocket science. Anyone can do it whether your location is legal or not. The trick is to keep it small and grow inside a cabinet or tent...
Unbleached parchment paper, like the kind I'm using, is good for 350 degrees F. I press at 180 degrees.
Using the unbleached paper eliminates the chemicals used to "whiten" the bleached paper. Chemicals like dioxin, for instance.
I also have a microscope and I see no paper being removed after...
If, by maximum pressure, you mean what your jack piston is capable of, then with a plate size of 4.5 sq. in the pressure will be 155.55 psi no matter the size of the puck you place in there.
My little press is capable of over 4300 psi based on the size of my plates and using a 12 ton press...
You must use unbleached parchment paper to stay clear of chemicals leaching into your rosin.
Here is a link to the paper I use. Bought it at Johann's Fabric & Craft Store for $3. There may be one near you.

I applaud your comments. I'm not a chemist, but I have also tried to educate readers on this forum and others to the inherent dangers of vaping these additives. Mostly, it seems to fall on deaf ears and I do not know why.
"I'm not sick now so what's the big deal" seems to be the response...
