Do not heat the speaker or the handle. These cups are not dishwasher safe. Hand wash only please!
In an oven you should always check as you go for the best results because different ovens do heat differently. I use 365 degrees and heat for 7 minutes. When you can see your image through the outside of the paper your cup is done.
In my press I do 385 for 40 seconds and flip for 40 more. Please remember to always check as you go either way you sublimate.
