What is happening if my Lamp produces a large flame but does not continue to work when this flame is extinguished?
It is most likely that the flame was extinguished before the stone had reached its working temperature. Put the Snuffer-cap on the Lamp and leave it for 20-30 minutes to prime. Light the stone again and allow the flame to burn for a full 2 - 3 minutes before extinguishing. Please note that after igniting the stone, the catalytic effect is optimised between 2 and 3 minutes. If this does not work it is likely your stone has become clogged. Follow the instructions below for "How do I clean the Stone?"
