Howdy! Does anyone have any thoughts on cutting cave stalgmites with an anti-freeze cooled saw vs. a water-cooled saw and the possible effects of such on oxygen and carbon isotopes? I've heard that anti-freeze will mess things up but I haven't heard how or why. Any help might save me a long days drive to the nearest water cooled saw tha'ts large enough. Thank you.
