All burners are individually hand made and so there may be slight uneven surfaces or minor ripples as well as variations in height and weight and colour texture. None of this will affect the functionality of the burner and is normal in the production of individually made products.
The lines of this burner give an industrial appearance, particularly in the silver finish. This is a modern, edgy burner unlike most of the wax melters on the market just now.
We do not recommend using the burner for any longer than 3 hours at a time.
