I was selling vintage furniture from a market stall in the 1980s when I first came across lava lamps, in an old box. At the time they were really unfashionable, but I loved them.
My then business partner and I approached the inventor, Edward Craven Walker, and asked if we could buy the formula to make our own lamps. He said: 'Why don't you come and take over the business instead?' And that was that.
