Is this not related to the practice of tempering steel?
Click to expand...

In some ways it is, and it some it is a totally different world.

"Glass" belongs to the group of materials called.... "glasses".
Glasses are non-crystalline ( amorphous when you go nerdy) solids. There are lots of other glasses than the traditional glass.
A glass is formed when you cool a molten material until it solidifies, but without starting a crystallization.
Because glass has a thermal expansion, uneven and rapid cooling will induce stress and strain. Quite often more than enough force to pull the object apart.
A controlled annealing will release the tension and reduce the risk of breaking.

Tempered glass is made by a rapid cooling of the surface. It makes the glass a lot tougher, but the price you pay is, that when it breaks, it really disintegrates (think car window). And any cutting and shaping must be done before tempering.


Steel on the other hand is completely crystalline, and the properties are decided by the crystalline phases present.
Steel with around 1% carbon can be hardened.
When we start, the carbon is present as cementite, an iron carbide (Fe3C) and the iron is primarily ferrite (pure iron)
If we heat it past 1000°C, the cementite dissolves in the iron and austenite is formed. If we cool it down again slowly, it will separate again, but if we quench it, the separation does not have the time it need, and we "freeze the high temperature phase". (Now it is called martensite)
The steel is now very hard, it will scratch glass.... and it will shatter easily.

So it has to be tempered by heating to a moderate temperature, to convert some of the martensite back. Basically you buy toughness and pay for it with hardness.

(This was as much as i could remember. Hardening steel is both a science and big money!)

Hell yeah! I think most of us who create something and send it off to a middle-entity for sale wonder what becomes of their creative offspring. I adore seeing my beads made into jewelry, my jewelry being worn by a customer, etc. I would imagine that a traditional artist would love to see where a piece has been placed and that the buyer is happy with it (and, going for the payoff, how much they enjoy it and why they purchased it in the first place). Sometimes if feels like writing a story but not knowing what the ending will be.
 
Total ego-rubbing!

It is nice to make something you are satisfied with, but it is even better, when someone else likes it!

This is a great explanaition.
 
How is Artfire working for you?

If you sell on Artfire, how has that been working out for you?

I joined Artfire in their very early days and it wasn't very well run, so I withdrew and stayed with Etsy. Now, with Etsy abandoning their early 'handmade' policies, I'm looking for a different venue, especially for kink-oriented goodies like my nipple dangles. I know from Fetlife that there are some active sellers on Artfire, so I'm thinking about giving them a second chance, presuming they are past their growing pains.

Any thoughts would be welcomed.

As a non creative who loves creative things, buying on etsy is a pain. So many mass produced stuff to filter through. I've practically given up. Last thing I bought was a light shade, barely as described that frankly I could have picked up in a DIY store. :(. I want to support creatives, not just aspirational creatives. :eek:

I'd love yo know if you end up on an international alternative you'd recommend.

I'm on the verge of starting my own website again, but the costs are in my way. (I ditched my site and my domain a few years ago.) I think I'll be selling a few things on Facebook in the meantime. There is a thriving bead-selling community (ok, several pages/groups) as well as some handspun yarn groups. But I think I'll be selling the "adult" stuff on Etsy. I'm also perfectly willing to ship overseas, always have been! I won't falsify customs forms (which has annoyed a few customers), but I'm well aware of how to ship "off and away."

The funny thing about shipping....I've kept track of every country I've sent beads to, over the years. The only time I've ever had troubles were shipping to Mexico, Canada, and Russia. Mexico and Canada were just loooong visits with customs, and I suspect the Russian was trying to rip me off (the same buyer filed claims with multiple artists, and we DO talk among ourselves LOL).

I am one of the last people in the world NOT on facebook. :) i have thought about putting a business page on there, interestingly, but for me personally? Nope. G has a page simply to be searchable by potential employers. ( it happens.) it also happens that some employers operate on facebook to monitor some employees over whom their are questions, like minor scale industrial espionage, lol.

Oh, I'm right there with you Elle.
No Facebook for me! It does nothing, absolutely nothing for me. Maybe I did it wrong when I experimented :p oh well!

And just where is the beautiful autumn silk thread I wonder?? :D

What do you spin on?

I love finding fellow fiber lovers. :D

I have a 25-year-old Reeves 30" saxony wheel. I also have a roughly 250-year-old great wheel. I travel with it for occasional demonstrations, and it's my favorite for spinning cotton.
