Generally speaking, you will need low temperatures for majolica. Firing at cone 03-04 should be more than enough for this type of ceramics.
Temperatures in a kiln are generally measured in two ways: by a pyrometer or by a pyrometric cone. Pyrometers are electronic thermometers which read the temperature inside the kiln. Pyrometric cones are pieces of ceramic formulated to bend at specific temperatures in a kiln. Most potters use both methods of measuring temperature because the temperature at which clays and glazes fire is very critical.
I would not suggest it. The oven elements will not get hot enough for kiln work. Since a kiln gets to the temperature of over 1400 degrees, the standard overn elements will not attain that temperature. Invest in standard kiln elements...and a good kiln thermostat.
It's due to the moisture in the clay evaporating.
There is really no set time on how long pottery need in the kiln. You just it to be at a certain temperature to get the effect like having it on low temperature to melt your glaze and some has to be on high to melt.

Greenware is typically fired at a lower temperature known as a bisque firing before glazing. For cone 04 clay, it is fired to around cone 04 temperature, which is approximately 1945°F (1063°C).

The optimal temperature setting for a microwave kiln to achieve the best results is typically around 1650F to 1830F (900C to 1000C). This temperature range allows for proper melting and fusing of glass or other materials in the kiln. It is important to follow the manufacturer's guidelines and instructions for specific temperature settings for your microwave kiln.
A Rotary kiln is a pyroprocessingdevice used to raise materials to a high temperature (calcination) in a continuous process.
It's due to the moisture in the clay evaporating.

Glass bottles can be slumped without a kiln by using a microwave kiln or a DIY kiln made from a metal container and a heat source like a propane torch. The glass bottle is placed in the kiln and heated to a high temperature until it softens and slumps into the desired shape.
Bottles can be flattened without a kiln by using a technique called bottle slumping. This involves heating the bottle in a kiln or a regular oven to a specific temperature and then shaping it using a mold.
1400 degrees F for two hours, then 22 hours to slowly cool.
