Rank noob needs research refs for 3d prototype

Not sure I'd mix sand in as well. If it melts glass it will probably also melt sand, which is after all unmelted glass.

Curious as to why/how microwaves can heat glass.
No OH stretch bonds and those are what microwaves mainly act upon.

But yep the clay moulds are the way to go.

Microwave kilns are insulated top-vented containers that go inside the microwave oven. These kilns are coated on the inside with microwave susceptor material. This allows microwaves to heat the fusing chamber to the necessary fusing temperatures. Commercial microwave kilns are usually 3-1/4" tall cylinders with a 4-3/4" radius. The kiln base has a 2" fusing platform.

I've found several tutorials for diy microwave kilns and will be able to fabricate shape and size more suited to my needs.

I will expand my research on making clay molds. Thanks.
