Spoon in the Glass

I got the glass work at yesterday, I put a spoon into the glasses.

– glasses that touching around the spoon cracked in the glass (not surface)

– naked parts of spoon are became to dark, black.

– The small safety pins also became to dark, black

*Probably these things were not ‘became to dark’…I think these things’ surface were peeled off, or melted.

– the air remaining in the glasses.

It was great experiment to know characteristic of the metal, and to know before melt and after.
