Is it safe to use a piece of Galvanised steel as a slumping mold in the kiln?

No. Search galvanized steel on the forum and you will get more than enough information on this topic.

Galvanized steel is coated with zinc, which will vaporize below 800°F (about 425°C). Zinc oxide fumes are dangerous. Google, "metal fume fever."

my question to that is, is it a one time thing though?
If I fire it once well ventilated are all the toxins released?

Construction fabric is galvanized, and usually, it all burns off in one firing. Then it can be encased in Bullseye Glass. I have switched to sandblasting the coating off, or soaking it in vinegar/alcohol solution. Less dangerous to ozone.
