That parch sticks. At least the 4x4 ones do. They don’t seem like they have silicone on them

I get them to flip fine and don’t get much sticking. Really tacky ones will, but that’s normal

You definitely don’t want them to have silicone on them.

What do you think parchment paper is? It’s paper with a very fine layer of silicone. Google will answer all your questions

Parchment paper
Modern parchment paper is made by running sheets of paper pulp through a bath of sulfuric acid[1] (a method similar to how tracing paper is made) or sometimes zinc chloride. This process partially dissolves or gelatinizes the paper. This treatment forms a sulfurized cross-linked material with high density, stability, and heat resistance, and low surface energy—thereby imparting good non-stick or release properties. The treated paper has an appearance similar to that of traditional parchment, and because of its stability is sometimes used for legal purposes where traditional parchment was used.

Bakery release paper
The stickless properties can be also achieved by employing a coated paper, for which a suitable release agent—a coating with a low surface energy and capability to withstand the temperatures involved in the baking or roasting process—is deposited onto the paper’s surface; silicone (cured with a suitable catalyst) is frequently used.

Silicone coated parchment paper is in the do not use category due to the silicone’s solubility in butane during purging which means silicone in your dabs.

I’m telling you it’s treated with silicone. If it’s not it’s not parchment paper. :man_shrugging:


Apparently why I quit using parchment paper and went to PTFE paper…my mind must have new that’s why it was ABSORBING my terps!

That Martha Stewart article is just furthering the common misconception mentioned in this thread and in this blog.

My previous reply was quoted directly from,

Parchment Paper(Wikipedia)

and if we look at the ‘Baking Sheets’ vs ‘Parchment Paper’ on the SAGA website here we can see one is clearly labeled as being coated in silicone, which though not a guarantee points at there being no coating on the other.

Now, after looking into the ones recommended earlier, are you aware the ones you linked are silicone and/or quillon coated @Dred_pirate?

They mention it on the Worthy Liners webpage here.

Maybe a good alternative would be something like:

A Bear Products listing claiming to use no silicone or quilon.

Anybody can type anything on Wikipedia. Not a credible source. Ever

Maybe it depends on what company made the parchment, as it used to be made from animal skin I’d say the name has been somewhat universal…

Silicone is part of this process @ like 2:45-2:55

I use vehicle oil filter pliers to open and close my ethanol containers. It keeps the lids nice and tight and you aren’t breaking your hands in the process.

Wikipedia has been ranked as accurate as Encyclopedia Britannica, and if you make a change to an important article that is easily verified, mods usually change it back within 24 hours, even less if what you changed had a citation that was peer reviewed. Wikipedia only sucks for things that don’t have citations. It can be a very credible source, especially for science related things.

As for tricks of the trade, I pull patties like taffy instead of whipping them to make crumble, it is so much easier to do, especially when changing unstable shatter to crumble.

Cleanliness.

I was not taught how to extract or run a CLS, I had to read/learn first hand, by myself. My trade brings a few things to the table…

I was getting a mol sieve together tonight. Just came in, my first one. As I was assembling it, I wiped all surfaces down with ISO. I looked at the 3/8 NPT weld joint on the hemispherical cap. The back of the welded joint, on the ID of the tube, had a bunch of soot and crud in it. I don’t know if they backed that joint with something or just back purged the weld or what. But both caps had a bunch of contamination in them…as seen in the pics on the q tips

When adding anything to my system, I treat it like a steam plant system. If it’s going in, being opened etc it gets a 100%, spotless cleaning with ISO or acetone…then gets a once over with ISO immediately before install if it wasn’t capped for foreign material exclusion.

Just my thoughts…not so much a trick but what should be common sense?

Are those the smallest rebuildable ball valves ive ever seen?

Might be just trick w lighting…but they look tiny! I love it, where’d u get if so

they are just small 3 piece ball valves…thats the next step up. probably 3/8 or 1/2

They are 3/8 ball valves. Nothing fancy here. You can adjust the pressure of the seats on the ball which I appreciate. These came from open source steel…they’ve got a decent deal on a molecular sieve at the moment.
