When the tubes are being bent is it important to retain the diameter. If anything restricts it the gas will struggle to fill it, affecting how the sign operates. To avoid this air is blown gently through it whilst the glass is still soft. This pushes the tube back to the required diameter.
A challenging part of the process is splicing glass tubes together to make larger neon signs. They are made from several sections of tube, all of which need to be attached together. To do this the end of each piece of tubing needs to be heated so they can be spliced together.
