Lapis Lazuli

Lapis Lazuli-Tutorial

Final piece for Lazuli

This faux lapis lazuli panel was completed for a specific client.  Lapis lazuli is a deep blue semi-precious stone (not a marble). Most lapis lazuli contains calcite (white), sodalite (blue), and pyrite (metallic yellow).  Since the stones do not come in boulder sizes (the largest sizes rarely exceed 12 sq. ft.), a larger panel like this needs to be broken up into sections.

In this tutorial, I will demonstrate the step-by step of the center square of this lapis lazuli.

With a 2-headed, pointed marbling brush, a very minimal background is created with a bright, yellow ochre to mimic the bright golden flakes encrusted in the lapis.  This is a guideline for the entire composition.

Once dry, a slightly tinted blue, slick coat is applied to the entire surface.  With a 2-headed, flat badger brush, add an overall texture of a blue glaze (using a mixture of Proceed ultramarine blue, black and pthalo Blue), leaving about 25% uncovered.

Switch to a samina chiqueteur and chiqueteur or “sponge off” to further soften and change the texture using a simply damp brush.

Deep “white” areas are created by removing glaze in a jagged, worm-like shape.  Here, a small, 2-headed pointed brush was used on its side to create this effect.  Soften the entire section with a softener (round or square)

Finally, using a 2 headed, flat squirrel brush, dipped in alcohol and on its tip, add some dark areas (black, raw umber, ultramarine blue).  Soften and let dry.   Step 2 is complete.

Once dry, glaze on a transparent, ultramarine blue and a dash of pthalo blue to give it that extra pop, and break up the glaze with a chiqueteur (we like the samina chiqueteur for small projects like this)

Using a small, 2-headed, pointed brush on its side, create a few fissures, placing them in the lighter, white opening sections created in the previous steps.  Soften lightly, as you go.

Continue making finer network of veins, connecting the larger fissures, with a small but long veiner.

The square is finished.  Let dry very well and reverse the tape to complete the other areas.
