Though I put some ice on my finger immediately...

I got my thumb burned my thumb at work. during my part time job.
The pizzas at of the place I work is are an unusual shape.
It's raised pizza dough by power of eggs, so it become like flower. The eggs used in the dough make it rise to look like a flower.
It's They're baked on in a smaller pan than we usually use, and  I serve them  carry it to the customers.
Then I was forgetting forgot to cover the handle, so, as at the moment I touched it, I burned/burnt got my finger burned a few.
I had have never been  got burned, how should I treat do my blister?
I will take care in future.

だいじょぶですか？！

Though I put some ice on my finger immediately...

I got my thumb burned during work.

The pizza place I work at is usually safe.

It is baked in a smaller pan that we use to carry to customers.
Then I forgot to cover the handle.
So, at the moment I touched it, I got my finger burned a bit.
I had never got burned before, how should I treat my blister?
I will be more careful in the future!

These are my ideas to help your notebook.  Please let me know if this is helpful! :)  Also, cover your blister with a band aid during work and let it air out at home.

*not sure whether 'pan' is the right word. I usually bake pizza's on an oven plate. Maybe someone else can comment. Otherwise one usually bakes something 'in' a pan (because it has edges, and therefore an 'inside')

**take care of articles (a, an, the), they seem to be your main problem in this entry.

And in my opinion, icing a burn is like putting a boiled egg under cold water (it cracks). Better to hold it under lukewarm running water to ease the pain. If you have a blister, it will heal in time. But like Catherine says: put some band aid on it during work and take it off at home.
