Soon after the box was opened the lumps began to take on a white powery coating of the monohydrate. Left exposed to the air the lumps eventually dried out to a white powder.

    You describe perfectly the product I buy here! It really looks like a mixture of mostly ice and a bit of powdery snow. As I showed in the thread I referred to, it is almost pure decahydrate.

    The ratio between "ice" and "snow" seems to vary between batches.

    Of course it does not make real sense to ship water, but it makes a LOT of "business sense" to sell water. Think about liquid detergent business... Or, think about liquid photochemistry business!
