In Topic: Let Me Show Off My Latest Raw Material

Today, 03:37 PM

Jed,  this is probably a dumb question, and it's probably just shale (or something I don't know), but does it have even a weak magnetism to it?  Do you think if you roasted the stone in a camp fire, it would be magnetic?  I probably just have iron ore on the brain and if so, I hope someone comes forward to correct me.

 

I've sent you some photos, via PM of a mineral someone posted to the little Iron Smelters group I belong to on Facebook, I can't post it here, because I really don't want to post someone else's photos in public without their permission, but they called the mineral siderite (iron carbonate).  I thought siderite was crystalline in form, like large crystals, but the photos shows more worn, sedimentary rock like you've got.  I thinking (more hoping) you might have an impure, shale-ish version of that.  It's lack of plasticity and extremely small shrink rate would support this, I think, maybe.  Possibly.  At the very least, it's not all shale.

 

It looks very much like your pictures. So it may have Mg  in it. That would explain the low shrinkage. I will try roasting some of the rock.  I do know that if I heat it up with a torch, it pops and explodes a little bit.  Nothing happens once it is milled.

 

 Roberta, my geology searching also mentioned Pierre shale.  I have two buckets of the granite as well.  It melts to a beautiful white.

Yes it does.
For all to know my level: I have one electric kiln and am converting one to a gas fired kiln. I have made my burners using a pattern I used when I built my first forge. I have created 2-3 glazes from scratch. I am stuggling with John's wheel throwing excercises. I struggle to throw a cylinder taller than 16 inches. And most of my clay ideas fail. I have made 10-12 ceramic flutes and am still struggling to perfect them. I have collected and processed raw material and have made my own ball mill. That about sums
Up my experience.

Tyler, your point is well taken. I will limit my comments on this forum to asking questions....posting my progress in my clay endevors,...and praising other's knowledge and successes.

I understand what you are saying..Yet it is my job and responsibility to vet my sources. One thing that defines the internet is that it is predominantely a collection of opinions with scattered referenced articles.

As you suggest, it would be easy to vet people's comments if they gave their level of expertise on the subject at hand.

Yet one thing I have enjoyed from this forum is the invitation for ALL to contribute. This tread tends to go contrary to that invitation.

I appreciate what Pres said earlier. He told his class that he didn't know much about the course material. Yet by the end of the course, all the students knew to whom to go for advise....him. It is the same here. Most can name the 20-25 experts on this forum. I appeciate when one of these makes comments on my thead.

In post garduate courses I had to site ideas and reference content. It was as if I had not earned the right to have an original idea until after I had letters behind my name. Please don't do the same thing to this forum...

I agree with vetting one's sources and reviewing other's experiences to help one along his/her own path. Yet I want to be the Devil's advocate for a moment.

1. The US government paid millions in grants to Universities such as MIT to develop a blue laser. They were not able to do it. The laser was developed by an engineering hobbiest in his garage working on a shoe string budget. He was not constrained by conventional thought within the field.
2. Columbus discovered the "new world" against the advise of the scholars of his time.
3. Soft white bar soap was discovered by mistake when a batch of soap was left in the mixing machine overnight causing it to be whipped up.
4. I have framed a quote from Dan Bennett PhD, University of Chicago:
"How monotonous the sounds of the forest would be if the music came only from the Top Ten birds."

There is something to be said for fresh eyes and minds in one's field which have not been limited by conventional constraints. This may be why most great ideas for new inventions are conceived by people before their 30th birthday....they don't know it's not possible.

Don't disregard ideas from the untrained too quickly. Their voices add to the music of the forest.
