Material:
- A large, closely fitted covered box or pail
- Wire netting
- Granite iron cooking kettles, with straight sides and closely fitted covers
- 10 to 50 lbs. mineral wool, for padding
- Cotton cloth or galvanized iron fitted lining
Place hinges on cover of box, and see that box or pail to be used as the cooker is large enough to hold one, two or three closely covered granite kettles or pails, allowing at least 2 inches of space all around and at the top and bottom of kettles.
If your kettles are not of the same height, place enough packing, not necessarily mineral wool, underneath the shorter ones to bring the tops of the kettles on a level.
