Potion of Eternal Flame[]
The Potion of Eternal Flame is a orange color, looking similarly to that of the Potion of Fire Resistance. It gives the Eternal Flame effect.
It is brewed from vanilla lava and a fire charge, giving it an unstable structure. It cannot be amplified, but can be elongated. Brewing it with vanilla redstone elongates it, and brewing the result fluid with a Plagued/Pure Tear (a Pure Tear, in this case) elongates it again.
The vanilla lava and fire charge used to brew the Potion of Eternal Flame.
