Just noted a post on another forum suggesting that some lapidary suppliers "fill" their tin oxide with talc.
It is too expensive to source from retail lapidary supply shops as they are doubling the cost and "possibly" using fillers.
Aussie Sapphire would like to place on record that we do not (and have never) adulterated any product such as tin oxide or other polishes with "filler". To be honest, I would be completely gobsmacked if any of our competitors did either. However, as we can only speak for our own products, we would like to assure everyone that our tin oxide is sourced from a high quality supplier and not altered in any way.
And just a heads-up, we dont double the per kilo cost either.
We encourage all people out there to shop around for the best value but in our experience, the retail lapidary suppliers in this country are reputable and you should feel confident in shopping with any of them.
cheers
