A kiln remembers every flame.
Now it can remember the wind and sun, too.

[Verse]
When renewable power is plentiful,
electric heaters warm a core of refractory brick.
Layer by layer, heat is held inside,
quietly waiting behind insulated steel.

[Spoken]
When production calls, controlled air moves through the core,
carrying stored heat back to the kiln.
No combustion in the battery.
No change to the clay.
Just dependable heat, ready for the next firing.

[Refrain]
Bank the heat when clean power flows.
Bring it back when the kiln door closes.
Hold the hours. Shape the flame.
Make tomorrow from the same old clay.

[Outro]
For tiles, tableware, and technical ceramics:
steady temperatures, lower fuel demand,
and energy that works around the production day.

[Sung Tag]
Bank the heat.
Shape what comes next." \
