Re: Cutting Seraphinite
I've production slabbed a fair amount of seraphinite on 18" and 24" saws running light mineral oil as the lubricant. Although the oil was typically filthy with swarf and black in color, I've never experienced issues with oil staining on seraphinite such as can occur with chalky turquoise.
But because seraphinite tends to be pricey, you might want to run an experiment on your particular material (and lubricant) as a reality check before introducing a large piece to your oil saw...
I cleaned slabbed seraphinite in clay kitty litter (oil sorb) followed by a soak in a bucket of soapy water for a day or so, then a soft brush scrub with soap and water, which is my normal procedure for anything slabbed with an oil lubricated saw.
