Techniques for CollectorsTrying to figure out how to polish this inner hole in Quartz drilled with an ultrasonic drill.
26th Nov 2011 05:25 UTCRyan Lay
I'm trying to figure out a way to polish the inner hole on this pendent? It is clear Quartz and the inner hole is drilled out using an ultrasonic drill and the problem is polishing the inner hole. If anyone has any ideas it would be greatly appreciated as these keep breaking from polishing attempts. I would also consider sending this work to someone if someone was interested in polished a couple of hundred of these?
Thanks and have a nice weekend everyone.

Try a series of silicon carbide grits with water (as a slurry) then acord or sturdy string small enough to pass through the hole....draw back & forth and cover all surfaces until smoother...then thoroughly wash & go to the next finer grit. Polishing can be done in the same manner....just be liberal with the slurry so as to not generate too much heat...this is why they break, too much speed from a rotary power tool!

The hole doesn't go all the way through a string won't work.

If you ever get it figured out, please post a pic of the finished product. I for one would like to see how it turns out.
Thanks

Having said that, however, I'd strongly suggest that unless you're selling these things for a large sum, surely it's not the kind of job you really want to spend the entire winter doing. Outsource it to India or China, they'll do it for peanuts.

If the refractive index of the liquid you're going to fill the quartz pedants with, is the same as that of quartz (R.I. 1.53), then you may find fine polishing is not required. Try filling one with glycerol (also called glycerine), it may have a close enough R.I. (1.47) to make the solid / liquid interface disappear.
Just a thought,
Regards,

Good luck.

You mentioned sending them out. If you decide to do this I have someone who might be interested in doing the work. Send me your email and I will send you the details and contact info.
