So for this you need a new material template, and a new inorganic material template. The inorganic material template doesn't matter much because the syndrome is in the material template its linked to. So here's an example material template from the basic STONE. The important part is at the end.
[MATERIAL_TEMPLATE:NAME_HERE]
These are the state names, adjectives and colors for the material.
[STATE_COLOR:ALL_SOLID:GRAY]
[STATE_NAME:ALL_SOLID:these shouldn't matter?]
[STATE_ADJ:ALL_SOLID:stone]
[STATE_COLOR:LIQUID:ORANGE]
[STATE_NAME:LIQUID:magma]
[STATE_ADJ:LIQUID:magma]
[STATE_COLOR:GAS:ORANGE]
[STATE_NAME:GAS:boiling magma]
[STATE_ADJ:GAS:boiling magma]
[DISPLAY_COLOR:7:0:0]
The modifier used to all values involving the material.
[MATERIAL_VALUE:1]
Temperature information.
