Need help with Macro patch

[Mark Fry]

I want to do some patch clamp experiments, in the "Macro Patch" 
configuration.  I am having some trouble finding good references on the
technique, and therefore, I am having some simple problems.  For example
what type of glass do people use

I would be thankful if somebody had some good references or personal hints
they could pass along.

Thanks in advance,
