Why would anyone want to burn Cedar Wood? Current price purchase price =
is about $2000 Au a cubic metre for seasoned timber, even in small =
sizes. Specialist wood yards are asking and getting $10 a kilogram for =
bowl blocks.

Any commercial wood which has been treated for rot or borers will =
contain toxic chemicals and these often persist as residues in ashes. So =
care is needed when compounding ash glazes.
I have an ash which throws a superb violet when compounded with cobalt =
carbonate. Mystified me at first then I realised fencing stakes had been =
burned in the bonfire.
Best regards,

Cedar is a wonderful kiln wood, as Les points out. We can get pretty
well all we want in BC, Canada, free of charge, from the bins full of
cutoffsoutside furniture and prefab factories, mostly in strip form. The
only problem with it is that when it's small and thin, it burns way too
quickly.

Hi Ivor -

I noted your comments about burning cedar with interest. Cedar is all I
burn in my kiln here on Vancouver Island.

The main reason for burning this wood is the great,long flames cedar
produces, hence great flashing on the pottery.

The other reason is that I have an ongoing supply of off-cut slabs that will
either wind up being chipped or burned. Therefore, I consider it
environmentally defensible to use this wood as it is being put to a better
use than being burned as a waste product.

Best regards from the other Ivor,
