As part of our fantastic project we will be exploring a range of glass fusing techniques, getting to grips with the different states of glass, moving glass from a solid to liquid and with various fusing temperatures, bending and casting glass. We will experiment with glass frit, stringers and confetti and use metal inclusions to create some amazing reactions. We will even grow our own bubbles in glass! To help shape our visual ideas we will be looking at the work of artists who have explored water as a theme. Our final exhibition will be a series of fused glass panels that reflect our water theme and exciting experimental journey through fused glass!
What great fun we’ve had!
In our first workshop we discovered that glass changes state from solid to liquid when heat is applied. We also discussed how air can become trapped between the layers of glass, forming bubbles during the fusing process. We created inclusions in glass by trapping different metals such as copper and aluminium between layers, these changed colour when fused together in the kiln. Copper oxide was mixed from a solid to a liquid and used to help us create a mass of aqua bubbles in glass – we are hoping these will resemble bubbles in water. To explore the movement of water we completed two experiments, bubble painting and marbling. We discussed how oil on the surface of water is repelled and when moved it swirls into magical patterns. We took a print of this and will use it as inspiration for our designs.
WOW! Our glass is amazing!
Our tests from workshop 1 are back and they are awesome!
Everything is sparkly and you can see different layers
The mica is like glitter and my copper has turned blue
Another experimental workshop!
We’ve been using fibre paper of different thicknesses to layer up into a relief design. When we fuse glass over the relief it will take on the exact form of the built up layers. This is called kiln carving. We had to take care not to build our layers more than 4mm deep as our glass is only 6mm thick. Using different glass frits, confetti and stringer to develop our designs took a lot of concentration and was quite uncomfortable! Jackie and Matt took us through the Health and Safety rules of handling the different types of glass, wearing a mask and goggles to protect ourselves from breathing in glass dust and preventing tiny particles reaching our eyes.
Jackie demonstrated how to bend glass stringers using the heat of a candle. We will be having a try at this in our science lesson.
