He found Dr.Boaze and Murdock with a kettle filled with coal.

The gas issuing from it had been burnt in a large metal case, such as was used for blasting purposes.

Now, however, they had applied a much smaller tube, and at the end of it fastened the thimble, through the small perforations made in which they burned a continuous jet for some time."[7] After numerous experiments, Murdock had his house in Cross Street fitted up in 1792 for being lit by gas.

The coal was subjected to heat in an iron retort, and the gas was conveyed in pipes to the offices and the different rooms of the house, where it was burned at proper apertures or burners.[8] Portions of the gas were also confined in portable vessels of tinned iron, from which it was burned when required, thus forming a moveable gas-light.

Murdock had a gas lantern in regular use, for the purpose of lighting himself home at night across the moors, from the mines where he was working, to his home at Redruth.
