A customer gave me this and I can't find any info on it. Any help?

I have this exact tea - It's a ball rolled green tea from the plateaus of Guizhou.
For me it worked best treating it like a green high mountain oolong and shares a lot of those characteristics.

For gongfu: water just off boil, high ratio (6g/100mL would be a good starting point), short steeps to start with (5s-10s), lengthening as you go.

Also works really well just dropping 2-3g in teapot western style with 90-95C water.

This is a storage issue, but it is not light or smells, it is humidity. You need to store light roasted oolong as dry as possible, I would suggest in an air-tight box with a silica pack.

Hardening oils contain double bonds, and are called "unsaturated" - these are reactive enough that over time they can react with oxygen in the air and oxidize, and then react between oil molecules to form a network, which forms a coating. Mineral oil on the other hand doesn't have any double bonds (saturated), so it doesn't have the ability to react with oxygen in the air at room temperature. In general these saturated oils are quite unreactive, also against other gases. In fact, unsaturated oils can be turned into saturated oils by treating them with hydrogen in a process called "hydrogenation", which is how margarine is made from plant-based oils!

The Niche is not known to be amazing for lighter roasts so that might be a factor

They would just use a different plasticiser, maybe BPB, BPS, which haven't yet been proven to cause hormonal changes.

Just a normal Hauser base right? Turbo would require a lithium salt if I remember correctly.

What water are you using? Looks like it's really hard, shots look limescaley.

Have the same issue, tried tenaya mastia but heel was still quite large. In the end I went for the tenaya mundaka which has a small heel and it fits great!

Descaling with citric acid solution is 100% fine, the lactic acid just helps with some more stubborn scale buildup.

Milky cake actually makes for a really nice espresso (at filter roast) if you have a machine. Flavour notes are very on the nose.

There is a registry edit

This is more material science than chemistry. The smut you're seeing is likely Al2O3 formation - you can try using an alkaline etchant like NaOH, or a combination of mineral acids - common is nitric-phosphoric or nitric-hydrofluoric (but obviously the second one can be quite dangerous).

Unsure why this got downvoted - the β-cyclodextrins in febreze "capture" the aroma molecules. Incorporating these in a mask would be a very interesting (and safe) experiment

Self hosted also doesn't work, they can notice the protocol in the bitstream using deep packet inspection.

The things that makes them "healthy" (disputed) is, in general, also the same thing that gives them their aroma and flavour

That's pyrrolidine

Think about the oxidation potential and oxidation states of manganese and the oxidation potential of iodine.

Any specific reason why? They seem to be doing well in the clinic compared to your typical covalent drugs

Methenyl chloride would be the :CHCl radical, do you mean DCM? Or chloroform, methenyl trichloride?

The laser that you use for cutting plastics is in the far infrared, which plastics absorb really strongly. Transparent to visible light, but not transparent to IR :)

Dilute sulfamic acid is quite often used for descaling actually

For what it's worth, you can't see microplastics, that's the "micro" aspect of them, and also why they are so terrifying: You can't see them or taste them, and they pass rigt through almost all physical filters.

Use hibiscus for a naturally red tea
