>I haven't tried it, but a teacher I work with says it works to iron the back
of the lino before cutting it to soften the tile for easier cutting.
a zap in the microwave might work.
In my experience, an iron does help to soften old linoleum. Of course,
it is still not as cutable as fresh linoleum. DO NOT STICK LINOLEUM IN
THE MICROWAVE by itself--this will lead to your microwave breaking. If
you have to use a microwave, put the lino in the microwave with a glass
of water--this will ensure no damage will be done to your microwave.
(This is also a good tip for warming socks up in the microwave.)
