Glassmaker

Oh I can’t find my calipers that I will need to shape Master John’s bottle! Sorry, I did not see you there. My name is Robert, and I am the local glassmaker. Every day I have to make sure that my fire is very, very hot. Then I melt the river sand in the fire for one week, until it is the same temperature as the furnace. Then I dip my blowing iron into the kettle. I then blow really hard to make the bottle. Finally I use calipers to shape the bottle until the bottle is the right shape. The most difficult part of my job is heating the sand, because I might get burned. Sorry, but I have to keep working.
