The Frostwork field of the Aragonite section should record any observation of frostwork.
Frostwork is fine, white, needle-like growths of aragonite crystals that look very much like ice crystals. Frostwork can appear in aragonite bushes which should also be recorded in the aragonite bushes field. Frostwork can also appear separate from bushes on popcorn nodules or growing from calcite crusts and coatings.
Frostwork crystals are usually short but can be many millimeters long in some situations. They often radiate outward.
Examine all popcorn carefully for signs of frostwork growing within it and examine any aragonite bushes for frostwork which may be present at the tips.
