This is honestly really easy to do
You can type the abbreviation of the element you want, e.g. dest ice gbmb sing dmnd dray
in the tools category there is a element called prop if you click it there is a menu opens and there is a setting called cType you click on that type a number (13 for ice) and click with prop on lava.
How to you do that? You modify the file of the save?
How did you melt water, diamond, and antimatter?
