That's basically the same as the M3 Mokume stuff without the meaningless technobabble then? I giggled reading the M3 site.
No,actually is not .
The M3 Mokume is a composite material consisting of clear epoxy (or maybe methacrylate ) resin and real metal particles ( aluminium ,iron ,copper,bronze,brass,tin,zinc,titanium ,etc )
and ,most probably, some mica pigments.
The pen blank vid shows the making of a composite material consisiting of two part epoxy resin andonly mica powders .
If you ask me I prefer the Resin + Mica combo ,more than the M3 mokume composite.
The M3 is not going to be lightweight (as it contains real metal particles ) and is subject to
corrosion ( they may call it "patina" ,still it is corrosion actually ) .
Lately ,I'm experimenting with composite epoxy materials and their use at the making of VC stems & mouthpieces .
Soon ,some new mouthpieces will be available.

Maybe even some new "cigar " type of Mica Composite (outer layer )
& Titanium ( inner tube ) stems will follow...
Mica is a very interesting material for the art .
Amongst many otheruses ,mica is also used ...
( ...) in
reinforcing additives for polymers to
increase strength and stiffness and to improve stability to heat, chemicals, and ultraviolet (UV) radiation; in heat shields and
temperature insulation; in industrial coating additive to decrease the permeability of moisture and hydrocarbons; and in polar polymer formulations
to increase the strength of epoxies, nylons, and
polyesters.
Wet-ground mica, which retains the brilliance of its cleavage faces, is used primarily in
pearlescent paints by the automotive industry. Many metallic-looking pigments are composed of a substrate of mica coated with another mineral, usually
titanium dioxide (TiO2). The resultant pigment produces a reflective color depending on the thickness of the coating. These products are used to produce automobile paint, shimmery plastic containers, high-quality inks used in advertising and security applications.
