  • Page 24: Instructions

    OVEN CURING INSTRUCTIONS Your Mugnaini wood-fired oven is made from Refrattari Cotto or refractory clay. The water used to form the clay must be cooked out before your oven can be put into use. Curing is the process of slowly heating an oven to first drive out the moisture from the oven components and surrounding mass, and then to temper the oven dome.

  • Page 25: Using The Door

    HOW TO MEASURE OVEN TEMPERATURE Mugnaini wood-fired ovens will self regulate based on the size of the flame and the floor temperature. We measure temperature inside a wood-fired oven with an infrared thermometer for accuracy. By checking the floor temperature, using visual cues and flame size we can create distinct repeatable oven environments for different styles of cooking.

  • Page 26: Starting A Fire

    Prior to starting the next fire, open the door slowly and measure the temperature of the sides of the dome paying attention to use the same spot each time you measure. Average left and right side temperatures and record on the chart. Commercial 180 x 140 Wood AOS Manual Mugnaini Imports, Inc.
