MEIKA – Catatan dari seorang sales, untuk Grading rules. Belum mendapatkan istilah Indonesia yang tepat, maka disajikan versi berbahasa Inggris.
Veneers are graded from the defects in the whole sheet of the veneer.
- Natural defects: sound knot, dead knot, burl, discoloration, worm holes, etc.
- Manufacturing defects: splits, rough cut, overlap, waves, etc.
Rough cut is caused by blunt blade. Splits, overlap and waves are mostly caused by over dried. Veneers are mostly dried to M/C 12-14%. If the M/C is over 18%, the veneers appear very flat and nice, but not good for storage.
Sound defects :
- sound knot.
- closed splits.
- rough cut.
Open defects :
- dead knot/knot holes.
- worm holes.
- open splits/cracks
- repaired holes/patches
FACE GRADE :
This is a general catalogue. Actually 2 grades are possible from it.
Open defects are not allowed but some scattered worm holes are allowed, which are inconspicuous.
Sound knots, burls and rough cut is accepted. Minor discoloration can be accepted
BACK GRADE :
Nearly the same like FACE GRADE. A bit more discolouration, 1 – 2 small holes, a few splits.
