MINERAL_TYPE: Oxide
MINERAL: Water_Ice (Frost)
FORMULA: H2O
FORMULA_HTML: H2O
COLLECTION_LOCALITY: USGS Denver Spectroscopy Laboratory faucet
ORIGINAL_DONOR: made from triply distilled H2O, USGS
CURRENT_SAMPLE_LOCATION: none (evaporated)
ULTIMATE_SAMPLE_LOCATION: none (evaporated)
SAMPLE_DESCRIPTION:
The sample was created by growing ice on a 77K cold finger from water vapor from triply distilled H2O from Gary Olhoeft's lab, USGS, Denver. The sample should have very little contaminants; being essentially pure H2O.
Measured at 77K.
