I wanted to do a few more glass items but not having much Dichroic aside from black and clear, I decided to smash a few bottles and see how that worked.
Bottle are hard to break. Unless of course you drop them on concrete, but I needed to minimise the mess and little nasty bits with kids and dog wandering around.
So with safety glasses on and hammer at the ready I put a board in the laundry tub, covered it with paper and break the bottles. Even with a board, the glass still bounced a bit and took about 6 hits before it succumbed to the pressure.
I have tried several pieces of each glass to see how they melt and if multiple pieces will join nicely.
The only difference between these and my Dichroic is that this stuff smokes like crazy and the fumes are really bad. Dichroic only smokes a little bit and the fumes are not so toxic.
Two windows wide open allows for good ventilation – providing the wind is blowing the right way.
A cold night is not the time to have glass cooking in the kiln.
A sunny day is definitely preferrable.
I have a brown piece, a green one I think would be perfect as a guitar Wrapture and there is a clear one with branches in the kiln cooling.
The glass goes into the kiln, reaching 800C then cooking for 30 mins. This is a one hour process. The glass is then left for at least 8 hours to cool and anneal properly. Although I did drop a piece on the floor and it still breaks like normal glass. Oops.
I would like to open the kiln at the 800C mark and stamp the glass while it is still red-hot and see how it cools. Hence my mention of gardening gloves. This will be something I try next time.
Here is the first piece of beer glass I made as a necklace.
All I want now is some of that pretty blue glass, or yellow…. wonder if the people at the tip will let me take it out of the recycling bins..
Keep smiling 🙂
