Polymer Clay Safety – reassuring words from the Doc!

Doc Sarah is the self-described “Guild Cheerleader and Web Tinkerer” for the PAPCG (Philadelphia Area Polymer Clay Guild) and as her username indicates, a medical doctor.   Recently, in a discussion about the safety of polymer clay, and concerns over the fumes released when it burns, she had this to say:

“The fumes of burning clay are an airway irritant. (The burning generates a low level of hydrochloric acid in gaseous form.) Basically that’s a fancy way to say the fumes stink and cause irritation. It is short lived. Of course children have smaller airways and may be more sensitive so it’s a good idea to keep up the ventilation to dilute the air. (if there is a risk of burning.) But don’t worry, there is no hidden toxic effect or delayed issue. If you don’t have any problems now, you won’t have any. Furthermore, if there is any irritation, when it’s gone it’s gone. You can’t take a product certified non-toxic and do anything to it to make it toxic. Burning will make it an irritant, but NOT a toxin per se (using medical definitions.)”

Doc Sarah is a helpful and sensible voice on the Polymer Clay Central forums, and she would probably want me to remind you that it is a good idea to wear some sort of dust mask when working with any mica powders or other particulate matter.  That will keep your lungs happy and smiling like the ladies she made from her first face cane!  (pictured above – she gives Barbara McGuire credit for helping her over come her face cane fears!)

Pottery Clay – DIY Divided Tapas Serving Platter with Illustrated Sections

Every good hostess knows a serving platter is the secret weapon at a party. It corrals snacks, makes everything look intentional, and saves you from running back and forth with little bowls. This DIY divided platter takes that idea one step further: each section is labeled with hand-drawn illustrations, making it both useful and irresistibly charming.

The original inspiration came from these  tapas-style platters, but we’re creating an English version featuring everyday snacks and nibbles. It’s fun, it’s functional, and it makes even store-bought crackers look Pinterest-worthy.

Materials You’ll Need

  • White ceramic clay (or air-dry clay if you don’t have access to a kiln) 
  • Rolling pin or slab roller 
  • Oval platter base template (downloadable below) 
  • Divider templates (downloadable below) 
  • Scoring tool + slip for joining clay 
  • Sponge and rib tool for smoothing 
  • Cobalt blue underglaze pencil OR blue underglaze with a fine brush 
  • Kiln + clear glaze (for ceramic clay) OR a food-safe sealant (for air-dry clay) 

Step-by-Step Tutorial

Step 1: Shape the Base

Roll a slab of clay about ½ inch thick. Place the oval platter template on top and cut out your base. Smooth edges with a damp sponge.

Step 2: Add Dividers

Use the divider templates to cut strips of clay. Attach them to the base by scoring and slipping. Smooth joins and curve the edges slightly for a handmade look.

Step 3: Refine

Let the platter dry until it’s leather-hard. At this stage, you can tidy the walls, soften corners, and make sure the surface is smooth.

Step 4: Draw Your Illustrations

Here’s where the personality shines. Using an underglaze pencil or fine brush, sketch quick doodles into each section. Keep them loose and playful, not perfect. Our platter has:

  • Cheese – wedges with holey details 
  • Ham – loose stack of wavy slices 
  • Anchovies – three slim fish outlines 
  • Sardines – larger, striped fish drawings 
  • Salami – one log plus a few round slices with dotted speckles 
  • Olives – oval shapes with pits, some sliced open 
  • Tomatoes – little cluster of round tomatoes tied together 

Note: Drawings are slightly altered from the original for a fresh, unique design.

Step 5: Fire and Finish

  • For ceramic clay: bisque fire, add clear glaze, and glaze fire. 
  • For air-dry clay: allow to dry fully, then paint with a clear food-safe sealant if you’ll use it for food. Otherwise, it makes a perfect decorative tray.
