Fibre Board kiln shelves

Stephen Richard

Some characteristics of fibre board as they come to me:

Light weight

Might need hardening

can’t be scraped clean of batt wash

need sanding for really smooth surface (or smoothing on something like batt wash or alumina hydrate)

Can warp over time even when supported every 100 mm

Will warp over time when placed on the kiln floor

Needs to be thick – at least 25mm

Possibly not much cheaper than mullite shelves

Fragile, but with care can last years

Need to use dust masks when ever working with fibre board

Good cooling characteristics as it doesn’ hold the heat the same way a mullite shelf does

There will be other things about the characteristics of fiber boards that others may add.
