Suspend objects

All the novelty stores sell all kinds of chochkeys made of glass with
objects, 3d reliefs, etc. inside of them. How do they do it?

They are not actually glass, they are clear acrylic resin. If you handle
them you will find them warm to the touch while glass is cooler to the
touch. Casting resin is available at most hardware and hobby shops. You
need the resin, the setting catalyst, separator to keep the stuff from
sticking to the mold and molds of some form. To put stuff "inside", it is
normal to pour a layer, let it firm up a bit, place the objects and then
pour another layer. It is a bit tricky because the layers have to be
different batches as the extra stuff from pouring the first layer will set
in the pot if you have extra. Also pouring over some objects without
getting air bubbles takes practice.

I don't really know but I'm under the impression that working with these
acrylic resins requires very good ventilation and other precautions for
health reasons.

The Swedish use laser to make internal 3d reliefs.

If the Russian's did not invent the process, they certainly made big use of
it first. But that is just images, not objects, which observed close up
show the little dots of "etching" where the two laser beams crossed.

Agree, but the warnings are all over the resin and not every posting has to
have legal notices attached - otherwise "Glass is heavy and sharp and may
....."

I had the chance to observe how it is done at a place in Utah. It's one
laser beam moving in an x-y axis and the z axis is done by the depth of
focus of the cone shaped beam. Pretty interesting operation.
