Hot black filled icon
Four wavy vertical lines representing rising heat or steam
About the Hot black filled icon
Four evenly spaced S-curves rise in parallel, the familiar shorthand for heat radiating off a surface or steam lifting from something freshly cooked. It carries warmth, high temperature and serve-hot meaning without any object attached, so it fits oven and kettle control panels, climate and thermostat screens, weather app summaries, restaurant menus and food packaging.
The curves share a uniform stroke width and identical amplitude, repeated on a square grid for a rhythmic, texture-like look. Pair it with fire, sun and snowflake icons for temperature scales. Because there is no outer container, keep clear space around it in toolbars.
This is the solid black filled version of the hot icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
