Leo started by demonstrating how a plane blade cuts wood, emphasizing the angle of attack of the blade. In turning the inside of bowls, raising the tool rest can alter this angle so as to make it easier to remove material.
When one sands off the bowl, more wood comes off the end grain than from the side grain as the bowl turns. Hence the wood turns oval as sanding progresses. Using "stones" to grind down the wood ( inside and out) works well to minimize this problem. A broken piece from an angle grinding wheel works well. The cutter can be scored on a grinding wheel and broken into pieces.
Using various grit and shaped sharpening stones works well.
Leo demonstrated how to apply gold leaf on Paul's vase. Size is applied, let dry until just a little sticky to touch and then apply the leaf. Use wax paper to pick up the leaf..makes handling it easier. Squish it into the grooves with a dry brush.. 2500 sand paper wet with paint solvent is used to sand off the leaf from the overlap and edges.

Supplies needed:
Gesso, made from the following ingredients:
Yellow ochre pigment: Whiting (sifted limestone)
(Not much yellow is needed)
Fish glue
Good brushes
Gold leaf
Transfer paper for real gold leaf
Eraser (rubber)
Paper towel
Paint the vase: brush it on well: spend a long time at this and do several coats
Sand between coats using paint thinner on the sand paper: start at 320
Spray on lacquer
Cut out the grooves again to expose the wood
Brush on concrete bond: let dry
Brush on the yellow pigment:whiting , mixing it with bond: this gives a very hard surface
Sand out the groove and recoat
Then brush on fish glue (or sizing)
Let it dry
The gold leaf is brushed lightly with water and laid in the groove.
The water melts the fish glue!
Apply the goldleaf gingerly and press it down using a rubber
Let it dry
Can do a second layer
Then burnish with agate
