Sgraffito Tiles

sgraffito, (Italian: “scratched”), a technique used in pottery, which consists of putting down a preliminary surface, covering it with another, and then scratching the superficial layer away.

 

I became interested in making tiles after watching contestants on The Great Pottery Throwdown. What I took away from terracotta week was incredibly helpful and inspiring, so I had to give it a try, plus I hope to own a home someday that I could customize with handmade tiles, so let’s call this a practice run :)

The Tools

The Steps

1
Roll out 3/4 inch (or 19mm) slabs of clay using a slab roller or hand roller

2
Transfer slabs to drywall boards for appx. 24hrs, cover with plastic until leatherhard

3
Use a square block (slightly larger than your final desired tile dimensions) as a guide to cut tiles (I used a utility knife) from the leatherhard slabs

4
Use a wide brush to paint on underglaze, drying each layer completely between coats (2-3 coats for an opaque finish)

5
Clean and trim tiles for sgraffito work

6
Use a banding wheel and carving tools to sculpt each tile

7
Place finished tiles on a drying rack until bone dry, no need to cover

8
Bisque fire

9
Glaze fire, with or without glaze applied

10
Install with grout and enjoy :)

A few Notes About Making Slabs

  • Start with clay straight from the bag, using a wire cutter to slice off blocks about 1.5 inches (or 38mm) thick

  • Use a slab roller or hand roller to roll out clay to your desired thickness

  • Use a pointy pin tool and a rubber kidney to pop air bubbles and smooth the surface of each slab before drying

  • When transferring slabs to drywall boards for drying, do so in a fluid motion so as not to indent, pull or alter the level slabs

Slabs for this project

There’s a slab roller at my studio so I opted to use that for making my tiles, but you could *easily* achieve the same quality slab using a rolling pin and two evenly sized sticks, as shown here by Pottery to the People. A canvas or fabric surface is best to avoid the clay sticking.
