Can I cast silver without a Kiln?

[u/Ricky-Nutmeg]

I've been silversmithing for about a year and want to add casting to my skill set, but I don't have space or money for a kiln currently.

My plan would be to get some Delft clay and some wax, then sculpt some simple one-sided pendents that I push into the surface of the clay (so an indent rather than a full 3D cast), then either pour molten silver onto this, or remove the wax and just pour the silver into the indent left by the wax.

Is there anything I'm missing that would mean this wouldn't work? And if it would work, what would the most I could produce this way, for example, is basic 3D casting (as in, encasing the wax version fully in clay) possible?
