Engaving a Thermal Mug

The first step is always to spray the special glass mixture onto the mugs as it's the glass micture that will melt into the metal to give the permanent engraving...

You can see that due to this special mixture Billy needs to wear special gloves and a face mask

It's then back to the laser where a sepcial holder is placed in the laser and Billy goes through a whole series of tests to ensure the engraving will be done correctly. This also involved a special pass with a low red light so he can eyeball that the cut will go on the correct place on the mug

Computer is interfaced with the laser

And there you have the finished product which is then washed and the final step is to dry and polish it for presentation
