just saw this on abr.. wondering if anyone has used it, and if you have any pictures/feedback.

yay

sounds poisonous...

[quincy]

Al2SiO5... shouldn't be toxic, never played with it though

Cyanite (http://encyclopedia.jrank.org/CRE_DAH/CYANITE.html)

[quincy]

some cool up close pics:

not toxic and works good

encases easily and is a neat orange color like moldavite

we just go this great stash of it cheap and thought that you all would like it!

thanks

I'd like to see a pic of what this does in glass

[jes]

Good day, here are some universe marbles I have been trying to practice the pictures towards the end of the post i used lots of kyanite in them it is orangish color and very compatible, I also like the fact that it is a rare earth mineral too. please cheack it out any ?????'s please ask, thanks jes

Those chunks of orange amber gold like splinters and chunks and stuff is kyanite, its in alot of them but most evedent in the last ones! peace

is that it on this matter?

[Greymatter Glass]

Hey Jes, Kyanite is actually one of the most common minerals on earth. It's Alumina Silicate, possibly the closest thing to natural boro you'll find.

For the crazy hippies it's also the only stone that doesn't require any cleansing or "discharging" and it absorbs negative emotion and energy.

I just never really didnt realize it was so abundant like that, cool, thanks, It sure dose seem natural too, its fun too, thanks doug. has anyone tried it I wonder what people are coming up with too?

[LunacyMountain]

kyanite is very abundant, but this orange kyanite is only mined out of Tanzania. There are actually only a few mines left mining this and they say in 10yrs there will be no more left, unless they find a new deposit.... be aware of a lot of lower quality stuff that is not even gemmy on the market. when it come to encasements the stuff is awesome and holds a very nice orange color, the stuff is not toxic unlike moldavite which is a tektite and very poisonous.

[jes]

OH wow sounds like you know alot about it? so is it one of the most common minerals on earth or not? I looked at it like a rare earth mineral that you cant just find everywhere, Tanzinia ????


Mainly I know the stuff really works, I am curious about Blue Kyanite that stuff works sweet too and is blue instead of orange, where dose it come from is it abundant too?


thanks for sharing your knowledge

How is Moldavite poisonous? It's essentially sand that was fused when a meteor impacted central Europe, and it's mainly silica, with a little bit of iron and beryllium....

As for orange, it's colored with manganese... so it's Al2SiO5(Mn+) it is a considerably rare polymorph of Kyanite, only coming from one or two mines in Africa.

Blue Kyanite is all over the place, pretty sure it's found on every continent. Alumina Silicates are some of the most common mineral compounds on earth, so the blue isn't going anywhere.

I had problems with blue and green kyanite burning out its color and just kind of looking clear. but I've seen it done and both to hold it's color, the orange never burns out it usually looks more rich in color after encasing. Moldavite is caused by a tektite collision and is classified as a tektite, it is not just glass.....it's not as toxic as solid black tektites which can be encased and I've seen worked a lot but that shit is highly toxic!!!

what about flame-fusion/synthetics like corrundum ?

[smolder holder]

beryllium= very hazardous! That stuff can cause cronic beryllium disease if you inhale just a microscopic bit and get it lodged in your lung tissue. Your body can (not everyone develops the disease) react like its having an allergic reaction and build up scar tissue around the beryllium. Which in your lungs is bad news. It does have a cumulative effect.

If moldavite does contain beryllium be careful folks.

Riley re: the flame fusions and encasement, the typically burn out at the temps required to encase. If you want to go the synthetic route then I suggest using Czochralski pulled minerals, corrundum included. they will hold up to higher temps. hope this helps save you some time and money.

Re; the color changing after encasement. The orange, blue and green kyanites will all hold their colors if you tube encase, keep the mineral out of the direct flame and keep the flame bushy and encase really slowly at a relatively low temp. when i do it, i often pull the tube encasement out of the flame and allow the glass to continue to gather/encase for a little bit before i put the tube back in the flame. this makes the process slow but allows you to get some of the more sensitive minerals in glass. this technique applies to some other minerals like black tourmaline (aka Schorl tourmaline). This technique will also help with minerals that eject gases at higher temps. basically, do it low and slow.

thanks dammond !

i am not really into any encasements at all. other than opals, i don't get why anyone wants to encase anything, it never looks as good as the gems/minerals look non-encased, boils, has c.o.e. issues, etc. but to each his own. this is with the exception of some mica, and copper mesh that i have seen look alright.

i have been interested in the red and pink corrundum as attachments.

i think the pink corrundum, with some facets, attached via black horns would look sexy as hell. their is obviously a huge shortage of rich pink tones in our boro color palette, and i think the corrundum would fill this void nicely.

on a side note, i found that the actual process of creating a boule of flame-fusion synthetic sounds rather simple, and alot of the process is reminiscent of some kind of boro powder application process. maybe i am over simplifying it in my imagination, but this doesn't sound too crazy:

"How gemstones are synthesized by flame fusion process?
This method is based on the melting of very finely pulverized alumina in an oxy-hydrogen blowpipe type burner. This requires a highly purified alumina which is prepared by repeated crystallization and later calcination of ammonium alum.

* The alumina is placed in a container or hopper which is tapped from above by a hammer at regular pre-selected intervals and regulates the flow of powder.
* This powder drops through the oxy-hydrogen flame, melts and falls on a rotating pedestal, where it solidifies.
* This pedestal is lowered slowly to allow cooling and crystallization of the corundum boule.
* The flame temperature generally ranges from about 1000°C to 2400°C since the melting point of corundum is approximately 2050°C.
* Both the growing crystal and the flame are protected from temperature variations by a circular ceramic heat resistant walled area.
* Boules are generally up to twelve inches, in size.
* The different varieties of corundum are obtained by adding various metallic oxides to the alum before it is calcined. "

Riley you are a wealth of knowledge. Thanks for sharing repped.
