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.
Ceramic paint when used to create a variety of handmade crafts must be fired in a kiln. Firing ceramic painted items in a kiln requires an extremely high temperature, usually in the 2300 degree Fahrenheit range.

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.

You can slump glass bottles at home without a kiln by using a microwave kiln kit. This kit allows you to heat the glass bottles in a microwave to the necessary temperature for slumping.
The kiln may be taking too long to fire because it could be overloaded with too many items, the temperature settings may be incorrect, or there could be an issue with the kiln's heating elements.
A kiln is a special oven used to heat ceramics and pottery at high temperatures. The kiln gradually increases the temperature to remove any moisture and then reaches a peak temperature to harden the clay and glazes. This process, called firing, transforms the raw materials into a durable finished product.
