The first time I did an anodic bond I used a hot plate and DC power
supply that were lying around.  Just to be cute I used a coat hanger as
an anode.

The bonds were as good as what I get now using a very high priced
commercial bonder.  I still get a lot of laughs over that hot plate and
coat hanger.

I would think direct fusion bonding in a standard lab furnace would be
difficult because of the differences in glass transition temperatures and
coefficients of thermal expansion between glass and silicon.
However, during my PhD days, I recall another student who reported making
his own anodic bonding setup with a hotplate and a HV power supply. He
reported success with bonding silicon to glass but unfortunately I never saw
the setup or have any more detailed knowledge of what he did! From my
limited knowledge of anodic bonding I believe you will need around 1kV DC,
about 500degC and glass with sodium ions (e.g. soda-lime).
