Natural Cork Sheet: Boiled Bark Sliced Flat

Cork is the bark of the cork oak, stripped without felling the tree. Boiled and pressed flat, a plank of it can be sliced into sheets for gaskets, pinboards and underlay, the same way the bark is prepared for stoppers. The picture: harvested cork bark stacked to season, Algarve, Portugal.

Beginner

A day, after seasoning

Instructions

Season, boil and flatten the bark

Season the bark planks, boil them for an hour and let them dry flat under a light weight, exactly as for cork stoppers.

Mark the thickness

Scrape off any hard outer crust. Gauge a line round the edge of the plank at the sheet thickness you want, for example 3 to 6 mm.

Materials for this step:

Cork Bark Plank1 piece

Tools needed:

Marking Gauge

Ruler

Slice

Stand the plank on edge against the band saw fence and slice off one sheet at a time, feeding slowly so the soft cork does not tear.

Tools needed:

Band Saw (Benchtop)

Safety Glasses

Sand flat

Lay each sheet on sandpaper on a flat board and rub both faces even. Store the sheets flat.

Tools needed:

Sandpaper
