Abstract:
1. A candle holder, comprising: a concave melting plate carried within a recess in a base; and a top edge of a wall of the base extending around the recess above the melting plate; wherein a projected surface area of the melting plate is less than or equal to about 20,000 mm wherein the surface area of the melting plate is more than or equal to about 2,500 mm wherein a depth of the melting plate from the top edge is less than or equal to a value of about a projected surface area of the melting plate divided by 1,000 mm plus the product of the sine of a zenith angle of the wall multiplied by one half the difference between a minimum distance across the melting plate at the top edge and a minimum melting plate width; wherein a minimum width of the melting plate is not less than about six times the product of a depth of the melting plate from the top edge times the cosine of a zenith angle of the wall; and wherein a width of the candle holder at the top edge is not less than approximately the minimum width of the melting plate plus two times the sum of an outside radius of the top edge plus the product of the tangent of the zenith angle times the difference between the depth of the melting plate from the top edge minus the outside radius.
