In the current work, researchers collected 100 marginal detections of silicates in Spitzer's archives and grouped them by brown dwarf temperature.

The suspected silica clouds, though hard to see or confirm, were right in the temperature range where silica can condense in an atmosphere: between about 1,900 degrees Fahrenheit and 3,100 F .Silica condensation is a matter of chemistry. Rock can vaporize, cool and condense into clouds just like water, although at higher temperatures.
