SHOT GLASS (1.5oz & 2.5oz) SUBLIMATION
There are a few important things to know about the shot glasses before you
sublimate. First the shot glasses are similar to all other sublimated
products in that the transfer and shot glass surface need to make direct
contact and reach about 400 degrees before sublimation will occur and glass
takes longer to heat than most products.
Secondly the shot glass needs to have a poly-coating in order to accept the
sublimation ink. Optimal image quality will be achieved using shot glasses
specifically designed for sublimation.
Sublimation shot glasses can be sublimated using a silicone wrap and a
convection oven. The directions for the oven are below a convection oven is
Thirdly because not all ovens are created equally the dwell time can range
from 11 to 14 minutes in an oven. Some experimenting with dwell time may be
necessary for best results. Directions for using a wrap in an oven are listed
USING A Silicone WRAP With Oven:
- silicone mug wrap (MGWRP4)
- sublimatable substrate (Shot Glass)
- sublimation transfer
- scratch paper
- Fan for cooling (DO NOT PUT IN WATER THE GLASS WILL CRACK)
- temperature - 400 degrees F 405 degrees if using a convection oven
- dwell time - 11:00 - 14:00 minutes (depending on the wrap and oven type)
- Silicone wrap pressure -medium
Note: The recommended settings above may need adjustments for best results.
Settings will vary depending on the oven brand and model ink and paper and
2nd Note: Be sure that the artwork does not go beyond the size/dimension
limits of the Silicone wrap.
3rd Note: Convection ovens are recommended over traditional ovens for even
distribution of heat however you will need to increase the temperature to
405 degrees F to compensate for the convection air that will have a slight
4th Note: Preheat the oven to 400 degrees F before placing the mug into the
oven 405 degrees for convection oven.
1. cut your transfers so that the transfer is slightly larger vertically than
the shot glass.
2. Position the substrate onto the transfer.
3. Tape two ends of the transfer. Make sure to start and end the transfer in
between where the white area starts and ends.
4. Wrap another piece of scratch paper around the shot glass and tape the
ends. This prevents ink from transferring onto the wrap.
5. Wrap the silicone wrap around the shot glass also starting in between
white area of shot glass and stretch and roll the silicone wrap around
6. Put a strip of tape around silicone wrap to prevent it from unwrapping.
7. Using the oven settings above stand the shot glass up in the oven. If
placing multiple shot glasses leave space between each to allow for proper
heat & air circulation.
8. Remove items from the oven after the appropriate dwell time using heat
resistant gloves if necessary - the items will be very hot.
9. Remove the silicone wrap tear off the scratch paper and the transfer and
put in front of a fan to cool.
- Do not place glass into water after sublimation - cracking will occur. Use a
- If the image of the final product appears light increase the pressure or
the dwell time (1-3 minutes).
- If the image on the final product appears blurred or substrate appears
yellowed or has brown spots on the rim of the top or bottom of the mug reduce
the dwell time slightly (15-30 seconds).
