Today’s discussion about the pieces that came from the bisque focused on effects we could see from the kiln.

Yes – continue even with the “failures” as we will learn something from the completion of the cycle of clay process.

If you fire Frit 3221 combined with bone china clay up to 1260 C – at a 50/50 ratio that is meant to mature at 1000 C - you can create a real mess – or maybe it could be art. The one on the right looks a bit like an anthropomorphic female/male. Guess this maybe one reason I am currently single.

Become more mindful of the subtle elements of making:
• Try rolling out the slab in several stages – rotate and flip the slab between
• cut the slabs width wise – since the stresses are in the length of the slab
more streach this direction
• using a less shape knife leaves a nicer edge to the tile
may reduce the need for sanding the bisque
• try using glaze on the leather hard pieces –
move them to a kiln shelf after they are bone dry using a board
• 1 mm slabs dry in one day
how fast can we fire them beyond quartz conversion
does reduction change the translucency
what is the influence of time – between 1100 – 1260 C
• try using sand to fire instead of a shrinking slab brushed with alumina
• thixitropic properties of slip – activate this using a massage probe – or concrete probe – result seems to be a very smooth surface – no need to glaze it then
Experiment with timing for slabs
Record it all – then evaluate best practice
Run experiments where hole are filled
Soft clay – mix clay w/glaze to fill holes – brass tube size for now
C 75 / G-25 _ C 50/G-50 _ C 25/G-75
Leather hard – Dry –Bisque
Same w/Terra Sigilatta
Try putting Talc on the mold – before making an impression -
May put just enough residue of talc on piece to achieve brightening effect

Find out where to place rings in the kiln to measure the exact temperatures achieved

T – testing for clay shrinkage and strength

Try a sandwich with lace inside of two slip slabs
If, one uses a wet knife to cut the slab or slip – it may not tear as much

Try .... to sketch these out clearly so you can remember where to being again in June - the next time or maybe on Saturday morning when you return from Delft/Rotterdam - Yes - they could dry before the last kiln on Wednesday!
