Last spring I was in Philadelphia and visited the Barnes Foundation. Afterwards I went into the gift shop. I was admiring a lovely ceramic persian tray and coasters. The items were a bit out of my price range, however, I examined them and thought "I can make that!"
Step 1: Barnes Foundation Platter
This beautiful platter was a larger version of the coasters I liked.
This platter cost over $200.00 and if I remember correctly the coasters were something like $27.00 each!!!! Wowza! I can make that!
Step 2: Supplies 1
I had some old chunks of red and white clay that was too hard to use for hand building with my students, so I decided to use it to make thick textured coasters.
access to a ceramic kiln
32 oz. yogurt container
Step 3: Supplies 2
mark making tools
I used rubber texture mats
number and letter stamps
other tools that I found
Step 4: Roll Clay Slab
first roll the clay into a piece approx. 12'X12'
Try to keep the slab about 1/4" thickness through out.
Step 6: Begin Texture
I first chose a textured rubber mat to roll an overall pattern into the clay
Step 8: Marking the Clay
using found and hand made items I began marking the clay. These are tiny dowels taped together to create a flower like mark.
plastic thread spool
paper clip glued to a film canaster
lid of an old film case
letter printing tool
number printing tools
Step 14: Cutting Coasters
When the slab is covered with textures and marks begin to cut coasters. Using the top lid of the yogurt container place it on the clay and carefully cut around the edge.
I like to make sets of 4
smooth edges with a sponge.
let dry and fire to bisque in a ceramic kiln.
Step 18: Painting
choose underglaze color to paint the 4 tiles.
using a sponge remove excess paint
leave paint in the marks made in the clay pieces
continue wiping away excess paint until coasters look the way you want them.
Then they will need to be glazed and fired again in kiln to serve as ceramic coasters.
Step 22: Magnets
The extra areas of the clay slab can be cut with smaller shapes and turned into refrigerator magnets
this one is a magnet using red clay and white underglaze.
