So close I can taste it...but far enough it will still probably take me another year or two to get it just right. Single glaze formula (no layering), hard cone 11 oxidation.    |

Looks like the images didn't make it to the post.

Yes. Definitely worth waiting for. Thanks Adam. I have wanted to get into iridescent for some time, even bought Greg Daly's book, only to find that his approach required reduction. Looks like you are definitely on the right track.
You clearly have some tiny, but well-defined crystals in the glaze. I'm not sure why you think the timeline for success would be measured in years.

Adam,
This is spectacular--just as it is--so I'll be great to see it when it meets your expectations!

It is very nice ! I would try it without crystalls and with a combination of different coloured glazes.

I'd like to get a vacuum chamber en.wikipedia.org/wiki/Dichroic_glassback in the way long time ago I had a job as a lab tech in an aerospace research company and we had a Vacuum furnace for chemical vapor deposition of silicon carbide coatings if any air leaked in during cooling there could be problems (like explosions)or these vibrant iridescent rainbows on the parts that the management regarded as rejects but i thought where super. i had a small piece of it for years and it never diminished must be around here somewhere |

Try Reduction on it. I think it should get even better

I thought it might be moissanite en.wikipedia.org/wiki/Moissanitethe picture below claims that its natural silicon carbide ore from oregon but it looks more like synthetic .this looks like the effect we got from CVD I think the effect is enhanced by the blackness of the SiC maybe a black glaze would be a good starting point  |

Gordon,
I edited your post to show the image. I am not sure how you are copying the image location in the first place but it seems you are copying a link to the folder that contains the image perhaps, or something of the like. Right click on your image and select "Copy Image Location" from the drop down to get the link you need to paste into the "insert image" window.

Jim, Found this on the "world" mineral dump at Sterling Hill. Believe its synthetic, a slag of some sort. Heated a piece to 1100c to see if it would melt but instead it fell apart. Silicon Carbide is quite stable, my kiln uses SiC elements. Gordon  PS thanks Greg this from the usual photobucket, that other try was from google drive which only seems to allow copying a URL, correct? |
