Take a piece of wire, and fasten it around the socket end of lamp; then bring one end of the wire back over the end, and fasten to opposite side to form a loop to hang it up to drip and dry.
This done, dip lamp in the coloring and hang it up, so it will dry evenly, when it will be found to be beautifully frosted.
When mixing your color, bear in mind the more dye and the less shellac the deeper your tint will be, and vice versa.
This method will apply to all colors except a deep red or deep yellow, when I recommend the other colorings I have mentioned, any of which can be removed with wood alcohol.
GENERAL ELECTRICAL INSTRUCTIONS.
Before proceeding with explanations of designs requiring special wiring, it is well for the amateur to become acquainted with the primary principles of electricity, without which he is helpless. The following notes we culled from writings of experienced electricians.
POTENTIAL OR ELECTRO-MOTIVE FORCE.
This (commonly E. M. F.) is the term used for electrical energy or power of doing work, and is used in the same manner as “pressure” is applied to steam; in other words, it is the term used to express the force which tends to move electricity from one place to another, and is proportional to the difference of potential at the two places.
The earth’s surface is called “Zero Potential,” and is a reference point to measure the relative condition of other bodies. A positively electrified body is said to have a higher potential than the earth, which in turn has a higher potential than a negatively electrified body.
When two dissimilar metals touch each other, there is a difference of potential at point of contact. If zinc is in contact with copper it is of higher potential. In a series of disks of copper, zinc and wet cloths, arranged one over the other in above order, the wet cloth is the conductor, and current will flow on joining last copper and zinc by wire, etc.
