Abstract
A candle capable of changing color when lighted is disclosed. More particularly, the candle incorporates thermochromic dyes that are a first color at room temperature and a second color upon being raised to an activation temperature. The color change is preferably reversible so that upon cooling, the portions of the candle that underwent a color change return to their original color.
Claims17
A candle having portions thereof which undergo color changes when the candle is lighted, the candle comprising:
- a) a wick;
- and
- b) a candle body surrounding the wick;
- the candle body formed of at least two segments, a first segment comprising a wax having a first thermochromic dye incorporated therein, the first thermochromic dye characterized in that it is a first color of room temperature and becomes a second color upon being heated to an activation temperature, and a second segment comprising a wax having a second thermochromic dye incorporated therein, the second thermochromic dye characterized in that it is also the first color at room temperature and becomes a third color upon being heated to an activation temperature.
A candle having portions thereof which undergo color changes when the candle is lighted, the candle comprising:
- c) a wick;
- and
- d) a candle body surrounding the wick;
- the candle body formed of at least two segments, a first segment containing a wax having a first thermochromic dye incorporated therein, and a second segment comprising a wax having a second thermochromic dye incorporated therein whereby the thermochromic dyes are selected such that the candle appears to be a single fist color at room temperature, but upon heating to an activation temperature the dyes change to second and third colors that are different from one another and from the first color.
