[BCMA] solidifying water

[Moderated BCMA subscriber listserv.]

Dear fellow museum people

I curate the small Greek Heritage Project Museum in Victoria and am setting
up a display about the Greek experience with coffee.

I would like to put a glass of water and a cup of Greek coffee on the
beautiful brass tray in the collection but don't want any chance of spills.
The display will not be in a case so danger lurks.

Can anyone suggest an inexpensive way to solidify liquids? cost is a factor
