Scottsdale Iron Pour 2010

I have a friend who takes an iron sculpture class at a Scottsdale Community College.  Twice a year there is an iron pour where the artists melt enough iron to fill hundreds of molds. In the spring it is done at a college with no room for observers.  But in November, visitors are welcomed and encouraged.

Last year, my first to observe, was held in the morning and I was quite impressed.  It takes a lot of careful coordination because the iron is kept continuously flowing and is heated to 2500 degrees. 

This year they held the event at sundown and I remembered to bring a camera. As impressive as it is in the daylight, it is twice as cool at dark when the iron is glowing red and the steam is rising off the poured molds.

This is maybe one-sixth of the molds laid out
One of the small plaque molds is mine.

The molds are laid out on a pile of sand.  This enables the molds to be leveled and catches any drips of molten iron.

The smaller open face molds to the right are the ones they sell at the iron pour for people to play with.


Last minutes instructions before the pour.

As you can see, everyone is wearing welders leathers and helmets with face shields.  This is too dangerous to take chances with.

The cupola is loaded from the top with iron and coke.  The molten iron pours out the bottom.  Slag exits from the side (hidden in this picture) 

Sparks everywhere

Waiting to lift

 One of the reasons for the protective gear. 

It takes two people to handle the ladle.  Here they are waiting for the last bit of iron to fill the ladle before they take it.  The fiberglass blanket keeps the iron hot  and prevents splashing.   

The first thing done with a fresh ladle is scrape off the slag, which rises to the top of the ladle.

Pouring the molds requires a lot of manpower.  The 2 ladle handlers can't see into the mold from their posts.  So there is a spotter that tells them when the mold is full.

Besides the spotter, there are one or two shovelers  that cover any overflow with sand and watch for fires.

Pouring a mold

Closer view

The amount of iron required depends on the size of the mold.  And the temperature of the iron varies within the ladle with the hottest at the bottom.

The detail of the mold determines whether it is poured first or last from the ladle.  The differing sizes of iron requires someone to calculate which molds can be poured from the current ladle.

Pouring ceramic shells

Some of the more delicate pieces are created using ceramic shells.  A wax design is created and the ceramic poured over it to create the shell.  These are preheated before iron is poured into them so the ceramic doesn't shatter.

Smoking and burning after being poured.

This is part of the reason for the sand base.  You can see the iron burning outside the molds where is over flowed.

The largest of the night.

This mold required 250 lbs of iron.  That took two ladles poured simultaneously.  One ladle was filled, then set aside with its fiberglass cover while the second was being filled.  Then the 2 ladles were poured at the same time.

I enjoyed the pour immensely and highly recommend it.  .

Cupcake to Eclair - geek, not foodie

I have been the happy owner of a Motorola Cliq for about a year.  The Cliq used the Android OS 1.5, called Cupcake.  (Not sure what is with the food fetish).

I had no real complaints, but as time passed, some of the apps being recommended to me would not run on Cupcake.  Although really, did I need the Kindle app?  Am I really going to read a book on a 4 inch screen?  But I am enough of a geek to dislike being behind in technology.

So I was thrilled when Android 2.1 (Eclair) was finally offered as an upgrade to Cliq users.  But the thrill didn't last.

I read ALL of the instructions.  And there were pages and pages of them.  Maybe that should have been my first clue.  I realized I had a cable for connectivity at work, so I downloaded the upgrade and installed it.  And it bailed on me.  It got stuck in a shutting down, booting up cycle. 

Another bad sign - there was a FAQ for just this situation.

I removed the battery as recommended.  That didn't stop the cycling. So, reluctantly, I did a factory reset, as the trouble-shooting guide suggested.  Only I couldn't finish the reset because I didn't have 3G connectivity in the office, nor did I know the password for the Wi-Fi here. I was NOT a happy camper.

When I got home, I set my Wi-Fi connection back up and finished resetting my phone. The good news was that the update was in place after the reset.  The bad news was that not everything I had downloaded showed up in My Download.  Among the missing, my 2 favorite apps, which I paid for, which I use nearly every day.

Anxious to get my phone back to its pre-upgrade state, I didn't bother to look for my receipt e-mails.  I downloaded them anyway and paid again. The one was only $3.  But the other was $15.  Impatience has its price.

Finally I got everything mostly restored and I was able to use my phone.  There were some differences I liked, such as the native widgets for turning Wi-Fi and Bluetooth on and off.  Some I didn't, like having to slide the lock icon instead of double-tapping the menu button to unlock. But overall, I was okay with it.

Then the next day I couldn't get my music to play.  I was frantic.  I was furious.  I Googled.  I talked to an Android compatriot.  Nothing. 

I had plugged my phone into my computer to remove the update file as required.  Only I didn't change the USB from drive to charge.  So the music wouldn't play.  I could argue for better messaging, but this instance was user error.

And it turns out that I really love the new Connected Music Player.  It even displays the lyrics for the song I am playing.  How cool is that!

So overall, happy with upgrade, unhappy with upgrade process.
