Thanks Marc, Mike, Alexandros
I haven't the photos SBS.
I use a ordinary epoxy. I paint only the bottom of a dark blue, but the epoxy did not tint. The depth of the base 1,5 - 2 cm and I poured a few layers (3-4), drying each layer. When the last layer begins to harden I'm starting to form "waves" using synthetic devices. It takes about 1 - 1,5 hours until the epoxy hardens.
