Here is a documentary on wootz produced by al pendray and how they think vanadium from one mine was the key.

Vikings managed to get some crucible steel and made the best blades of the day with it:

I would happily pay for the entire collection of ACOUP posts in book form. This is the kind of history I wish they had taught me in school but didn't.

I definitely encourage everyone to donate (just $3.50!) if you want to support academics doing great public service aside from their main job (he is an adjunct).

I wish people would provide not just a Patreon link but also a direct payment option. I would love to support this effort, but I do not want to sign up for a Patreon account or a monthly subscription. I'd much rather just make a one-time donation.

The sad news is that the credit card scammers have ruined this - automated credit card testing often looks for small donation pages like you're suggesting, then uses them to check if stolen card numbers are valid. This leads to chargebacks, loss of reputation by the donatee in the eyes of the card processor, and a whole bunch of wasted time. One of the "services" that organizations like Patreon actually perform is to take on this risk on behalf of their clients.

I guess bitcoin/etc payments are still OK, but except in some small niche subject areas, aren't generally accepted enough to make the direct donation setup worthwhile.

A paypal link would be fine. As would a physical mailing address where I can send a paper check.

this. in one of the projects I am working on, we have this problem exactly. automated credit card testing problem for small donations.

we use Stripe API there. And Stripe is just suggesting to pay more for their radar check, which in our opinion, put more burden on both donors and the organization.

Same here! There are plenty of people I would happily give a one time donation to, but signing up on Patroen or giving up details beyond my email address are too big of a step. I’d even settle for a Venmo address.

How would you send someone a Venmo payment without giving out any personal information?

Patreon is garbage. Would happily kick this guy a few bucks via Apple Pay or whatever though.

Put some money on a Visa/AmEX/etc. debit card and drop it in the mail.

lisper wrote at 2020-11-07 01:05:47:

A paper check is probably a better idea since a prepaid card is effectively the same as cash. But either way I still need a mailing address.

btc wallet address (or another coin of your choosing)?

Given the number and variety of services I've signed up for online, handing over all sorts of PII, the odds that _Patreon in particular_ ends up being the data- breach / misuse that causes me significant annoyance seems ... minuscule.

I've paid quite a few people small amounts by limiting the number of months I'm subscribed.

YouTube creator AvE is a good example, I pay him a few tens of dollars every couple of years, but never stay subscribed via Patreon very long as I derive no extra benefit personal for doing so.
