Having completed the mould and sprayed t with Graphite, I took the mould to be blow by Topglass in Wocestershire. I was very nervous about the whole process and didn’t have a lot of hope so I was only looking to achieve 1 successful form. However, the process was extremely successful and I have ended up with 4 forms; 2 clear, 1 white and 1 translucent black, which i’m am very pleased and relived about!
The first think we did when we got to the studio was drill and number of small holes into the mould to let the air and steam escape when the glass is blown into the mould. The glass isn’t in a liquid enough state when being blown to take impressions of these small holes. Likewise, any cracks in the mould were not major enough to show up either. The only time you started seeing defects was as we blew more forms, bits of the mould started breaking off and because I didn’t have any more graphite, the glass did take these impressions up, but still, this wasn’t very noticeable.
Following prepping the mould, The glass blowers got the glass ready by making it into a vase shape with a ball of air at the bottom. Once this was ready it was a swift process of taking the glass ball out of the kiln and pacing it into the mould, which was already prepared with two sides together.We then fitted the third side around the glass and held it very firmly in place with six pairs of hands to ensure the pressure of the glass inside didn’t lift the mould apart. The glass blower then blew into the mould and the glass quickly expanded into the mould inside creating a lot of steam. When he was finished blowing he would tap his food to signal us to take the mould apart which we duly did to reveal the successful form. The glass was then cut of and put in the kiln overnight to cool down slowly so it didn’t shatter.
I chose to have a white glass piece as well as a black one which I am really pleased I did as I think the black works really well, showing the forms really well. See below for a full length video of the process.
