How To Make Faux Ocean Jasper with Polymer Clay – Step by Step

Materials:

• Translucent Polymer Clay (Any brand, I used Premo)
• Alcohol inks: coffee/brown, yellow tone, orange
• Black polymer clay
• White polymer clay
• Pasta machine (or acrylic roller)
• Ball tools (one large, one small)
• Sharp tissue blade
• Backing clay (black, brown, or scrap)

Step 1: Create the Translucent Color Sheets

• Condition the translucent clay
• Roll it out on the thinnest setting of your pasta machine.
• Divide into three equal pieces.
• Color each sheet with one alcohol ink shade: coffee, yellow, orange. Let dry.
• Roll each coloured sheet again through the pasta machine on the thinnest setting.

Step 2: Stack and Reduce

• Randomly stack the three coloured translucent sheets.
• Pass the stack through the pasta machine on a medium setting.
• Cut the stack in half, place halves on top of each other, and roll again.
• Repeat the cut-and-stack process 2–3 times until you see soft blended layers.

Step 3: Prepare Black & White Contrast Sheets

• Roll out one sheet of black clay and one sheet of white clay on a thin setting.
• Layer them together and roll again until smooth.
• Cut this sheet to match the size of your translucent stack.
• Place one sheet on top (white side facing up).
• Place another sheet at the bottom (black side facing down).

Step 4: Add Jasper-Like Texture

• Using a large and small ball tool, press random dips and impressions into the clay stack
• These indents will form the round, organic “stone” layers typical of Ocean Jasper.
• Compress the clay back into a square block shape.
• Let it rest for 10–15 minutes so the clay firms up slightly.

Step 5: Slice and Build Your Veneer

• With your sharpest tissue blade, slice off very thin sheets from the block.
• Lay these slices onto a sheet of backing clay (any colour or even scraps).
• Gently roll flat with an acrylic roller or pasta machine.
  
• Start at the thickest setting and gradually reduce to 2–3 mm thickness
  

Step 6: Use Your Jasper Sheet

• Cut veneers for jewelry, beads, or decorative elements.
• Bake according to your clay brand’s instructions.
• Sand and buff for a buttery shine, or add a thin layer of resin for extra gloss.

Result: A richly layered, organic faux Austrian Jasper sheet, warm browns, yellows, and oranges framed with striking black and white contrasts.
