These blanks are from sustainable plantations so are not available in large sizes (or a wide range of sizes) and supply may not be continuous as the millers process each plantation; we have to accept whatever size blanks their trees have yielded.
The blanks are cut in the country of origin to provide local employment so we are selling them just as they arrive. The ‘bowl’ blanks are square (not round as we bandsaw most blanks) and all are waxed on all surfaces.
This wax does eventually crystallise but in the meantime does inhibit moisture loss, so most blanks will be part seasoned at around 20% + moisture content when arriving here - we had them checked.
As a guide to moisture content, we normally dry our blanks to 14% to 18% (it may be higher in the centre of 3” and 4” blanks) and central heating will take all timbers down to 8 or 10%. So some movement is to be expected after turning and you should not expose them suddenly to high temperatures.
