Default Borax granular vs 20 Mule Team

Are these the same? I'm looking for the 3 grams specified
for the
Microphen substitute in Darkroom CB.

A few years ago someone contacted the United States
Borax Co, the maker of 20 Mule Team Borax. It is chemically
pure, at least enough for photographic purposes and is
granulated. It should work in any photo formula calling for
Borax. Red Devil Lye is another "grocery store" product
(although I haven't seen it recently) that is pure enough
for photo use where sodium hydroxide is called for. One can
make the equivalent of Kodalk (sodium metaborate) by
combining the hydroxide and Borax in solution in the right
proportions.
