Abstract
Abstract A surface of a wooden object is decorated by the formation of tracks in the surface simulating the random pattern of tracks seen in wormy wood, the tracks being formed by the application to the wood of a high voltage current.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
92 words
A method of decorating wood, which comprises providing a pair of electrodes in proximity to a surface of the wood, applying a high voltage current of from about 6,000 to about 25,000 volts to said surface of the wood across said electrodes to initiate the burning of at least one track in said surface, reducing the voltage across said electrodes after the initiation of the burning of said track to a value no lower than about 1,000 volts and controlling the burning of the wood to obtain a random pattern of tracks.
Claim 2
Independent Claim
92 words
A method of decorating wood, which comprises providing a pair of electrodes in proximity to a surface of the wood, applying a high voltage current of from about 6,000 to about 25,000 volts to said surface of the wood across said electrodes to initiate the burning of at least one track in said surface, reducing the voltage across said electrodes after the initiation of the burning of said track to a value no lower than about 1,000 volts and controlling the burning of the wood to obtain a random pattern of tracks.
Claim 3
Dependent Claim
22 words
The method according to claim 1, in which said surface is dampened with water prior to application of said high voltage current.
Claim 4
Dependent Claim
20 words
The method according to claim 1, in which said surface is dampened with water after the initiation of said burning.
Claim 5
Dependent Claim
18 words
The method according to claim 1, in which at least one of said electrodes directly contacts said surface.
Claim 6
Dependent Claim
16 words
The method according to claim 1, in which said pair of electrodes directly contacts said surface.
Claim 7
Dependent Claim
43 words
The method according to claim 1, in which said high voltage current has a voltage of about 10,000 volts at the initiation of said burning, and the voltage of said high voltage current is then reduced to a value of about 6,000 volts.
Claim 8
Dependent Claim
28 words
The method according to claim 1, in which the high voltage current is reduced to form at least a portion of the track with a substantially reduced depth.
Claim 9
Dependent Claim
28 words
The method according to claim 1, wherein the high voltage current is applied to said surface during a fraction of the total time of treatment in pulse form.
Claim 10
Dependent Claim
14 words
The method according to claim 1, in which said surface is a curved surface.
Claim 11
Dependent Claim
22 words
The method according to claim 1, in which said wood is selected from the group consisting of natural woods and synthetic woods.
