Etchant

The metal plate was a piece of aluminum flashing that I†™ d cut, masked, and etched with a rubber stamp and some PCB etchant solution. ❋ Unknown (2009)

 PCB etchant solution etches aluminum wicked fast, so if you try this at home, watch it closely. ❋ Unknown (2009)

Hydrofluoric acid is a powerful bone etchant and -who knows why- people develop erosions in their enamel when they move from Brisbane North to Gladstone, a city affected by dental erosion but also skin allergies, asthma and probably cancer for some specific locations. ❋ Doyle (2009)

Jayve moved the bubble four times, etchant fumes searing his flesh, collar of his nanoskin pulled over his mouth and nose to breathe through. ❋ Dozois, Gardner (2006)

He clutched his net bag, half-panicked touch racing over the surface of the insulated tins within until he was certain the wetness he felt was rain and not the gooey ooze of etchant: sure mostly because the skin on his hands stayed cool instead of sloughing to hang in shreds. ❋ Dozois, Gardner (2006)

The etchant eroded crystalline sealant, staining the corroded surface in green, orange, violet. ❋ Dozois, Gardner (2006)

Heedless, heart racing, Jayve extracted the first bottle of etchant, pierced the seal with an adjustable nozzle, and — grinning like a bat — pressurized the tin. ❋ Dozois, Gardner (2006)

Warm developer and etchant do speed up the process, but keep an eye on your board's progress! ❋ Collin Cunningham (2010)

Keep etchant away from any metal you don't want etched - including stainless steel sinks! ❋ Collin Cunningham (2010)

The etchant tends to bleed under the edge of the paper and give a hazy or ragged edge to the design. ❋ Sean Michael Ragan (2010)
