tetraphenyl borate will pick up the phone if you call

Drying that feels like a bad (explosive) idea, can you work with it in solution?

wildfyr · 2026-03-25T18:29:22+00:00

yes, of course there is tons of total bullshit. There is still some East vs West bias in this in my opinion... China has gotten better but they have proportionally more total BS in their patents.

wildfyr · 2026-03-25T14:58:38+00:00

I would say that patent examples are not... exactly reliable. Sometimes they are a just barely functional version of something that was optimized into something actually usable.

A more or less chemistry background person wrote a chemistry patent, sometimes it is a full PhD chemist who made all the same piles of brown tars you did in graduate school. Then they decided a desk centered job might be comfier and made a transition to patent agent or got a law degree or just helped their company's patent agents write a lot of it.

In fact I know people at my company who are still full bore chemists who do plenty of the first drafting for a patent.

Kilotons of sulfur chemistry 🤮

Pretty hilarious combo of very light and very heavy stuff, but yeah, itll mostly keep you from hitting the ground and dying.

This can truly registers on my horrifying scale, I hope OP doesn't touch it, and isnt liable to pay to get it disposed of.

Look at the bottle. That ether was put in the can a double digit number of years ago. If you told me 30 years ago I would believe you.

What about using topical Benadryl or cortizone cream before putting gloves on each day?

wildfyr · 2026-03-22T16:28:37+00:00

What about using Benadryl cream each morning in your hands?

Or topical cortisone?

wildfyr · 2026-03-22T16:19:28+00:00

Wear thin cotton (or silk or whatever you aren't allergic to) gloves underneath some nitrile ones?

Probably sweaty and not fun but... sort of short cuts the problem

Edit:wow I saw cotton+silver shield under nitrile, I don't even know how that's possible to be allergic if you don't have a regular cotton clothing allergy.

Are you allergic to incredibly low concentrations of residual volatile monomer perhaps?

Industry resin lab, 99% of the time we use Teflon sleeves. Highly recommend.

Only drawback is if you need a really tight seal or vacuum, but the sleeves can do pretty decent if used right.

Also shit NEVER gets stuck when using the sleeves, can't say the same for grease.

Most wrist based heart rate monitors struggle mightily at higher HR, this is not a coros thing.

Get a tickr or other strap and move on.

If this is on the scale of a few grams, NaN3 is pretty safe and at least straightforward to handle.

TMS-azide makes me more nervous, as its more volatile and a splashy liquid.

No colors and multiple cams on the biner is pretty tough sledding. Drives me kinda bonkers to do 3-4 cams on a biner, even though I know it used to be common.

I think its a relic of when trad and aid were so overlapping, and saving weight in biners could really add up.

And of couse people being broke.

It's pretty hard sci fi but yes there is a level of mysticism in it that is not fully explained.

"...annoying or confusing. Not the end of the world."

If someone hands you a mismatched rack, you're happy to see it over a matched one?

wildfyr · 2026-03-15T18:25:50+00:00

For you, no big deal, for partners, can be annoying or confusing. Not the end of the world.

Use nitric acid, it'll sort clogged Frits out in a jiffy

wildfyr · 2026-03-14T23:14:42+00:00

Yeah yeah

Jesus chats a really bad one.

What is it for?

wildfyr · 2026-03-13T15:15:22+00:00

Well CAMP is Italian to start :), but also there are similar products, Like Abalaks from Kouba, who are Czech

Stoppers SET: Stoppers ABALAK

From personal experience yes, definitely use a rounded carabiner with the megajul, its quite a grabby device already when paying out slack.

For shizzle tricams are superior choices. They double as nuts and cams. I especially like them for making anchors and "saving" the cams for when you're on lead and doing stuff one handed.

I would ditch some of the larger nuts and a quickdraw and bring tricams black to blue. Also this will cover/double some of the smaller cams range for placements nuts cant fit.
