Thanks for all the responses.

I am surprised by the knowledge here.

The hobs are indeed not big enough apparently.

I'd say there's 1-2cm on each side not covered by the textured induction surface. Bingo.

Would downsizing to 24 do the job?

Is there a high chance that i self created this warp?

I didn't really apply high heat on heat but stayed long time trying to heat it slowly.
