Hello - again.

I just went through this on my LS-12. The oil didn't have the same clarity after filtering through bags. It still worked just fine when I put it back into the saw.

As another member replied in the original thread containing this question, some materials leave a permanent discoloration in saw oil. I cut some old estate chrysocolla once that colored my oil blue-green. Even though the rough didn't show the typical signs of dye treatment, I always assumed someone had treated that rough with "Tidy-Bowl".

That's interesting and explains what has happened as you and the other member were so gracious in answering. Glad to hear that this coolant can be reused. Just have to get used to the black ink color.

Since this is an issue of oil, which comes from cutting and grinding etc.  You could go here:
http://lapidaryforum.net/group/index.php?board=41.0

That's a whole section of the forum devoted to such things.

Will do ... Excellent suggestion.  IV

Dear Friends .... This may have been discussed somewhat an I appreciate your patience & understanding concerning this matter. I drained the Light Mineral Oil from a small 12" slab saw and filtered it through several brown paper bags. The muck was removed, however the oil did not clear up.

Seems as though an ultra fine dark suspension of matter may be still left in fluid discoloring it. Otherwise the filtered fluid looks to be reusable? Would like to what others say about this? Thank you very much!  IV USAF 62-66

some minerals leave a permanent color in the oil. Psylomalene and laguna lace come to mind.  i'm sure there are others.

As per suggestion I'm going to repost this in an appropriate forum for further discussion, if you will? Thank you for taking the time to analyze the matter.  IV USAF 62-66
