What about materials with a metallic appearance ?

[Bennett]

Thanks Mark & George for the answer.

 I purchases a preowned Genie with well used wheels and I didn't want to wear them down too quickly.

Here is another one for the metalic thread. Native copper in matrix. Pictures are not that good but you can see the copper shining mixed through the matrix.

Nice Slab Seth:)
I love all the metallic stones.
Hope you show us the finished design please.

I am not sure about this one..

If Amphibolite is considered a metallic or not.. Apparently it is from Africa. Have not cabbed it yet.. Saving it for a bit..

Anyone ?

I think what you are showing is called bronzite ...

according to other sites:

Enstatite is magnesium silicate, MgSiO3, with the magnesium partly replaced by small amounts (up to about 12%) of Fe+2. In the bronzite variety, (Mg,Fe)SiO3, the iron(II) oxide ranges from about 12 to 30%, and with still more iron there is a passage to hypersthene. The ferriferous varieties are liable to a particular kind of alteration, known as schillerization, which results in the separation of the iron as very fine films of oxide and hydroxides along the cleavage cracks of the mineral. The cleavage surfaces therefore exhibit a metallic sheen or schiller, which is even more pronounced in hypersthene than in bronzite.  The color of bronzite is green or brown; its specific gravity is about 3.3–3.4, varying with the amount of iron present.[2] The refractive indices and optic angle increase with iron content. The enstatite endmember has a positive optic sign, whereas bronzite and hypersthene both show a negative optic sign.

The more greenish variety with a a silver sheen is usually called just hypersthene. The schiller pattern is  caused by metal oxide formation and thus appears metallic. Many of the materials listed in this thread are not true metals (in the chemical sense), but do show a "metallic luster" like hematite (an oxide), pyrite (a sulfide), covelite (another sulfide), rutile needles (esp. in quartz - another oxide),  etc.

Bronzite gets it's name from the fact it resembles bronze in color.

Thank you Ron !

You enlightened us earlier about the difference between a metallic and metallic appearance..

Going to change the title of the thread accordingly

Here's my piece of Bronzite again with the metallic looking flaky texture.  You can see the flakes in your piece also George.  I have only see enstatite as a mineral specimen, but there is quite a difference between the way the three forms look.  Hypersthene has really small flakes that are more like barbs and it kinda resembles shiny lead.

Now if i can only get a trim saw blade to work, I might try cabbing a piece.  I will have to go back and check the thread where Ron or someone talked about banging saw blades near the edge to make them cut again.  George, do you remember where that was posted?

I think you are taking about a post by Tony within a blade thread I started.

[Mark]

Thanks George, that's what i wanted.  Not exactly sure what i am supposed to do, but i will go bang my trim saw blades so maybe i can cut out some preforms.

Today is my every other Friday off, thank God.  We all hate the every other long 5 day weeks.  So i have a 3 day weekend.  The wife is finishing the kid's costumes for Halloween, she makes them all each year.  This year they are really cool.  I'll get a pic later. She is incredibly talented when it comes to art quilts, fabric arts, sewing, etc. 

I want to do a little cabbing and decide if i need a new entry for the cab contest or if what i cabbed last week is fine.

I don't mean to put Tony on the spot, but am pretty sure he would not mind me letting ya know..

He offered, although I never did send my bad slab saw blade to him for repairing..

I bet if you dropped him a PM you could work something out with him..

He mentioned being pretty good at getting these back in shape !

[Mark]

I should do that.  I have a $275 DP/MKxxx blade that I bent the first week i had it.  Not sure that my trim saw blades are worth repairing.  Ya know those little suckers cost more than the green blades i use in my 14" slab saw.  DP uses a 1" diameter hole so that no one else will make blades for the Genie Trim Saw attachment.  OK, off to the basement.
