Sealing Crystals

Some of our great neighbors (the W family) gave us a Rock Crystal kit a little while back. The kids loved it, of course, and finally talked me into making crystals with them last week.

I explained that at first it just looks like a rock in liquid, and they were fine with that. We set our little box of potential crystals up above my bill desk and let them sit. We helped the kids check on it periodically.

Within a few days we had lovely crystals on our rocks.



Apparently, one of the children checked the crystal box without help at least once and bent one corner down just enough to make a tiny hole in the plastic.

So the crystal water leaked out slowly but surely onto the surface of my desk, splattering on everything else within range and sealing the roll top shut.

Does anyone know how to clean up a crystallized roll top, or alternatively, does anyone want a slightly used desk?
