Mistakenly didn't put a glass plate, printed for 3min on the heating plate

Dear all,

 

Long story short: I accidentally didn't put the glass plate on the heating plate.

I printed for about 3 min  on the heating plate before I realised I left a plate on the sink after cleaning.

Could you please tell me how can I remove it without damaging anything?

Is it too far gone?

 

Thank you,

Paulina

I would warm the plate up to 75° or so and gently scrape it off with a putty knife.  It should be fairly round since without the glass there would be no squish to the build plate.  You do need to try to get the surface flat.  You wouldn't want a high spot in the middle that could cause the glass to rock back and forth.
