Brenda, if they're that runny, you may be using glazes designed for a lower
temperature. But to adapt the ones you have there, you need to add more
refractory stuff. If I were you, I'd do a series of tests, adding in
increments of 5% clay of some kind, either kaolin or (if it's a dark glaze)
ball clay. However if it's really that runny, you may find that if you add
enough clay to stop the running, you'll have a completely different-looking
glaze.

Arnold's suggestion of the chisel is good. Then give it a good grinding on
your bench grinder to get rid of any traces of glaze. And put some kiln
wash or silica powder over the spot next time you fire.

Because the glaze has dripped on my shelves, does anyone have a great way to
repair them?
----------------
Wearing safety glasses, hold an old chisel at a sharp angle against the
shelf. Gently tap the chisel with a hammer to remove the melted glaze.

Hi Brenda -
One - see Paul Lewing's reply to this question.
Two - Please use kiln wash on your precious shelves (they're expensive,
yes?) that way any drips should come off either with the pot, or they'd be
relatively easy to get off (Arnold Howard's reply) without damaging the
shelves too badly.
Kiln Wash: equal parts Alumina, EPK and Silica.
Re the recipe above: there are many effective variations of this recipe.
Buona fortuna,
