DYKEM High Temp Marker

This ink is specially formulated for marking surfaces exposed to extremely high temperatures. Once written at room temperature and allowed to dry, the mark can withstand temperatures up to approximately 1093°C (2000°F). It can be used to mark almost all non-porous surfaces, including metals, glass, and ceramics.
The Hi-Temp Marker has a built-in valve action mechanism that prevents the ink from drying out. By pushing the pen tip inward, ink is supplied to the tip. The valve action mechanism also prevents the ink inside from drying out even when the cap is removed.
The pen tip uses a fiber tip, which wears down with use, but can be replaced with a spare tip sold separately.
The ink dries in approximately 45 seconds to 1 minute.
*While it can be safely used on most surfaces, please perform a surface test before use.
