I have been following the thread on cutting irons in water. My
question is, why distilled or purified water rather than tap water? I
was under the impression that purified water, i.e. ultrapure water, is
much more corrosive than mineralized water like spring water or tap
water. In fact, ultrapure
Hi Carl,
You raise some very interesting points that I had not considered. :)
It has been my understanding, that tap water or non-distilled water
may contain chlorine. It was also my understanding that chlorine is
very destructive to certain components within meteorites and that the
chlorine
Hi Steve and hope all is well. Forgive me if I am crossing the line here,
but I noticed quite a few more emails from you lately. Are you back in the
hobby of meteorites? Reason I ask is I thought I read an email in the past
that you were breaking away from the hobby. Anyways, just was curious.
Who knows what chemicals lurk in tap water? By purifying it, you are removing
the unknowns. I have
seen, for lack of a better term, Lawrencite disease creep up, especially with
tap water that contains chlorine which seems to accelerate the
problem. I have had no issues cutting with
Adam, Mike, Carl, and list:
The main constituents in pure water that cause corrosion are
dissolved gasses. Does anyone de-gas their cutting water?

Hello Everyone,
This week I have some more spectacular impactite offerings very much
worth giving a look. Several have been listed as Buy-It-Now while
others were started at very reasonable auction prices. There are not
many of the melt rocks remaining and the endcut listed will likely be

I fill all my old distilled four litre jugs with tap water and let them sit
with the caps off for about seven days.
A chemist buddy of mine said it takes about 24 hours for any chlorine and other
gasses to dissipate, but with the narrow neck and relatively small cap opening,
to be
Pete and list,
Unfortunately the method you use does not effectively de-gas water, as
exposure to the atmosphere will allow atmospheric gasses to continue
to dissolve into solution; it is the atmospheric gasses that cause
water to be corrosive. To de-gas water you can:
- Boil it
- Sonicate
Hi Michael,
Is there a method to calculate how long to leave a specific volume of water
at a specific vacuum (inches Hg) to ensure that it is degassed?
Thanks,
Ed

Ed and list,
I do not know of an exact way to calculate, but a few minutes at
around 29 inches Hg of vacuum (sea level), especially on a hot plate
and with a little aggitation, will remove about all of the dissolved
gasses.

Hi Folks,
I wanted to clarify that my personal experience is mostly with stony
types. While I do appreciate irons and pallasites, I avoid cutting
them. I've had a couple of near-misses while cutting irons. On one
particular occasion, I was attempting to cut a window into a small
Whitecourt
Seems to me that if you recirculate the water, all that out-gassing is for
naught as the blade will re-aerate the water.

I purify water in a closed system, reverse osmosis so I assume most of the
gasses are discharged with the brine.

Hi Greg and all,
I tried each one = same result: SOLID BLACK, though there is a
little + sign - I suppose that is related to the problem.
I have had others off list contact me and say they got the same
results as I - but obviously some on the list are seeing the images. Too
Bad.
Wow, can't wait.

Hi Don,
I'm surprised you were only able to detect the first layer of a multi-layer
image!...
As I have learned, 'The Black Phoenix' is not easily revealed... ... ... I
did hear she might have a video that was 'accidentally' released earlier...
