I have this image in my head of someone engraving letters or patterns onto a piece of wood (flat or not) or on metal (but it doesn't have to be both, either wood or metal is fine) with an instrument that is made of metal (iron?) and it is red-hot, which is how the work is done. I am sure there must be a word and it is used in art, but not only.
My first guess was incise, but it does not involve fire/heat:
to cut the surface of something carefully with a sharp tool (Cambridge)
Is there a verb that describes the same action but using fire or a red-hot metal instrument? (I wonder what the name of that would be also, but my main question is the verb).
The result looks something like that
I need it for a metaphor:
This experience was _______ in the depths of his being as with a red-hot iron (instrument - could it be chisel?)
Edit: I should have mentioned that the experience is not necessarily negative, though it may involve pain. In fact it is not. It has just been indelibly engraved in the soul.
