Question about Dremel 400 Series Xpr Rotary Tool Kit with Xpr Multisaw and Xpr Planer Attachment 400 - 6/90
Whats the best way to get a good shiney finnish
I made a pear of earring with the lapis and put them in the pickle solution, as the resolt the stons lost color. The serfes got a whitish mate color and lost luster.
I thryed to tumbler them for two days but it did not change anything.
I will appreciate if you can help me to solve this problem.
Lapis is a porous stone and should not be pickled if possible. The pickling solution is an acid and has soaked into your lapis and reacted quite a ways in. Next time, try painting on the solution with some care when working with porous stones. Look into some geological books for more information on the stones your working with, their porosities and reactivities. Or like when working with cloth, test out a small peice of the stone first. As for your jewelry, Im not sure if its recoverable. There is the possibility of a chemical bath or heating solving it, or possibly grinding away a LOT of the stone. You may need a chemist or more acurately, a geochemist. If your willing to experiment, I think heating will likely be your solution. Try something around 200-400 for a short time, and dont set fire to anything. Remember that the metal could melt around there depending on what you used to mount it. ::shrugs:: if your using these things, dont rely on anything like this without some research first or experimentation of your own. Get a good jewlers jem book.
