Bottle slump inclusions

[Flowers]

Hi everyone
I was wondering whether it is possible when doing a bottle slump of say a clear bottle to try and place some different colour glass or millefiori inside the bottle so that when it melts there are other colours included.  Is this possible to do? If it is not what would be the best way to add patterns or colour to a bottle slump?
Thank you

all the glass would need to be the same COE,   not sure that if you used a bottle that you could be sure it would all be compatible.

Cheap idea: little shapes in thin copper sheet, or wire, or Glassline paper. Mica powder.
Expensive idea: loose dichroic powder, either CBS dichroic 'extract', or the sort you buy on copper foil and flake off. (check the Warm Glass site).

These would go with any coe.
