Youtube videos document the process from start to finish. 4 videos in all... definitely worth watching if your interested in agate carving.
The last video shows a final treatment of the carving after polishing. Looks like the carvings are being dipped in a heated solution. If anyone knows what they are doing please clue me in!
Thanks,
Dan

that is a fascinating video(s)....i followed what they were doing right up to that last heated step too! those finger protectors in the first clip looked interesting and i'd love to know what kind of saw and blade that was for the first rough cuts. that was very interesting, Dan, thanks for posting those!

Glad you like the vids KD. That saw blade cuts agate like butter huh? I think it's cool that most of the carving is done using saws. Sort of the same thing that I do...

Thanks for sharing them Dan! They are so interseting. That saw has an incredible cutting speed, it makes me doubt that is agate, though the look is clearly agate.
After vibe, they first use an ultrasonic cleaning bath. And the last treatment ... I don't know, I only suppose it might color the stones. They look a bit purple after the "boiling", but one can't see clearly.

very cool Dan, thanks for sharing those. I suspect the that heated mixture at the end to be acid polish. Its a common practice to use acids to polish stones when cost is the main factor. However, it may be a different chemical process for polishing stones. Otherwise why would they of cleaned the stone before polishing it?

The videos were awesome! I enjoyed them a lot!
I can see where the one rotary tool would be easier for the carving than using the dremel all the time like I am!

Dan,
I believe the heated solution was waterglass , it appeared to be an older mix as there was a bit of white moving about in the tub. It would be impossible to tell how long the pieces were in solution but would guess some time to cover small scratches and unpolished areas that the vibro did'nt reach.

Nice vids Dan. Interesting process. Wish my saw worked a 1/10 of the speed of there saw. Looks like there are a bunch more rock related vids there. Now I have to look at them all. Thanks for ruining my day.  |

Hi,
Watching the video reminds me of some material that I cut many years ago.
Australian Dendritic Opalite.

I believe the saw is an opal, or jewelers saw. Very thin, and cuts fast. If the link works, this guy is demonstrating one. video.google.com/videoplay?docid=-7272727978374494056&q=opal+cutting&ei=Q9o4SNXPG4SE4gLoldTpAw&hl=enNow the water glass had me scratching my head. I have not heard of this before. I had to look it up. Here is what I found. water glass water glass or soluble glass,colorless, transparent, glasslike substance available commercially as a powder or as a transparent, viscous solution in water. Chemically it is sodium silicate, potassium silicate, or a mixture of these. It is prepared by fusing sodium or potassium carbonate with sand or by heating sodium or potassium hydroxide with sand under pressure. Water glass is very soluble in water, but the glassy solid dissolves slowly, even in boiling water. Water glass has adhesive properties and is fire resistant. It is used as a detergent; as a cement for glass, pottery, and stoneware; for fireproofing paper, wood, cement, and other substances; for fixing pigments in paintings and cloth printing; and for preserving eggs (it fills the pores in the eggshell, preventing entrance of air). I have some Banded Opal that is great looking, but full of pin holes. I have been filling the holes with Super Glue. This may be a good alternative. |
