I love using the microwave kiln - I now have 2 small and 1 large. I also have a large regular kiln. The 2 small ones are great for rotating two projects without waiting for it to cool down. I really only use the Ney furnace for large shapes. I love how fast this process is in the microwave. The only problem I have to watch out for is touching the glass after touching my oily face. The glass will crack. Have fun and just do it.
