About the Heat black outline icon
Three wavy lines rise in parallel above an open, flat-bottomed tray with short upturned ends, a simple way to show heat radiating from a surface. It communicates warmth, cooking temperature and hot-surface caution. Use it on oven and heater controls, appliance labels, food delivery apps showing a hot meal, weather widgets, and laundry care symbols.
The tray is wide and low so the waves dominate the upper half, which is what gives the mark its heat reading. Pair it with thermometer, snowflake and flame icons for a temperature set, and keep vertical padding so the wave tips are not clipped.
This is the black outline version of the heat icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
