I LOVE the Liquitex acrylic inks- I have them in a variety of traditional colors and I've been using them constantly in my paintings so thought I'd go ahead and splurge and get the metallics. I actually have other brands of metallic acrylic inks (Daler Rowney) and they are really vibrant and very metallic, so I assumed the Liquitex would be similar.
Unfortunately, the Metallics are not really that "metallic". There's definitely a metallic/sparkly sheen to them, but they are sort of oddly goopy in consistency, so you'll get a clump of metallic in one part of the paint, and then just a gold sheen and then another clump of metallic, even when the acrylic ink is THOROUGHLY mixed. I guess the particles aren't fine enough, and the binder in them is not tinted enough. They also don't "flow" well- I usually drip acrylic ink on the canvas and then tilt the canvas to get it moving before I work it in with my brushes, but this sort of sits there a bit before it just FALLS down in a blob. It's very odd.
I would guess that I got an "off" set, except the black and white colors in this set are marvelous and perform really well- they are both perfect consistency and go on the canvas like a dream. I'm flying through the white.
So it's sort of an iffy thing- if you want really great, vibrant metallic inks that will really POP on your artwork, this might not be the set for you. But if you want something a lot more subtle, sort of like a gold sheer powder effect, you might like these.
