Re: Identifying asbestos

seems like the general consensus is quartz ,mica etc sliders are not as important as differing refraction oils
my question now becomes I did not know of anything other then the immersion oil I use for 63x and 100x objectives where do I obtain such a wide variance of oils

Re: Identifying asbestos
