Blank 20cm Glass Dye Sublimation clock, ideal for a personalised gift or promotional product. Square mirror clock with sublimatable round clock face and digits.

Warning: Glassware is susceptible to thermal shock, ensure the blank is heated through to at least room temp before putting in your heat press. Not doing so may result in the glassware cracking due to the extreme heat change.

Getting a nice even pressure distribution across the blank is also vital to avoid cracking it under the pressure of the heat press.

As well as keeping your pressure light It’s recommended to always put this clock in the press face down so the top heat platen is coming down on the completely flat side.

Further to this using 100% polyester fabric (linked below) as your top cover layer will help further by giving you a barrier between the heat plate and the glass directly touching as well as helping to further even out your pressure distribution.
