Peter Glasby:
The front of the kiln

The calcination tube inserted into the front of the kiln
Peter Glasby:
The building up the chimney at the front of the kiln.
Peter Glasby:
The back of the kiln with the steel calcination tube resting on piece of marble. Note the spacing.
Peter Glasby:
The flap at the back of the kiln with the hole in the ceramic fibre wool. This arrangement protects the burner from the heat of the fire box. The burner in this case is a Teclu Burner, but can be replaced by something equivalent.
Peter Glasby:
Looking back into the fire box from the chimney end
Peter Glasby:
The working kiln with the burner going and a glass tube extending from the calcination tube taking the vented gases through the conical flask containing dilute red cabbage juice.
Peter Glasby:
The inlet to the Red cabbage juice goes to the bottom of the vessel ensuring the gas travels through the juice. The outlet has a rubber tube on it which takes the gas into a jug, to be poured into glasses and tasted.
Peter Glasby:
The calcination tube being emptied after 45 minutes

Slaking the thirst of the thirsty quick lime
