Works at silver clay shrinkage rates of 8–22%
Plenty of margin for trimming and finishing the join

How to Measure for Your Ring Band

A ring band wraps the full 360° around the finger, so your finished band length equals your finger circumference. Because clay shrinks during drying and kiln firing, you need to start with a longer piece of clay than your finished size. Follow these steps:

Measure your finger circumference snugly in mm (or use a ring sizer)
Add 2–3 mm ease for comfort
Multiply by the factor below to get your starting clay length (accounting for shrinkage)

Clay Type	Shrinkage	Start with this much MORE clay	Multiply finished length by
Fine Silver (e.g. PMC3, Art Clay)	8–12%	~10–14% longer	× 1.09–1.14
Silver clay (higher shrink)	15–22%	~18–28% longer	× 1.18–1.28
Copper clay	20–28%	~25–39% longer	× 1.25–1.39
Bronze clay	25–30%	~33–43% longer	× 1.33–1.43

Example: Size M women’s finger (52 mm circumference) + 2 mm ease = 54 mm finished length. Using bronze clay at 30% shrinkage, start with 54 × 1.43 = ~77 mm of clay — well within the 145 mm mat. Even a men’s XL (68 mm) at 30% shrinkage needs only ~97 mm, leaving plenty of spare mat.

How to Use

Apply a release agent to the mat before use
Press your clay firmly onto the mat
Peel away carefully to reveal the impression
Use a strip/straight cutter to cut your desired shape
Wrap around a ring mandrel at the correct size before drying

Important Notes

Always use a release agent to prevent sticking
Please be aware that the pattern detail will appear smaller after firing — the higher the shrinkage rate of your clay, the more the design will reduce in size. This is normal and expected with all metal clays
