Abstract
A fuel for producing attractive audio and visual burning results is disclosed.
Claims10
A crackling gel fuel comprising
- a fuel source, a gelling agent, and microcapsules containing a solvent wherein said microcapsules have walls that are cross-linked and are double-walled and said walls comprise about 30% of the microcapsule weight, and the size of 50% or more of said microcapsules is 900-1200 microns, effective to maximize crackling sound when burned.
A water soluble fuel composition providing a golden flame and generating a crackling sound without excessive smoke comprising:
- a flammable lower alkyl alcohol,
- a flammable non-aromatic organic compound effective to produce a golden flame during combustion, and
- microcapsules containing a flammable organic solvent different from said non-aromatic organic compound and said lower alkyl alcohol wherein said microcapsules have walls that are cross-linked and double-walled and said walls comprise about 30% of the microcapsule weight, and the size of 50% or more of said microcapsules is 900-1200 microns.
A water soluble fuel composition which, when burned, provides a golden flame and a crackling sound without excessive smoke comprising:
- a flammable lower alkyl alcohol in a concentration amount effective to enable said fuel to maintain a self-contained flame,
- a flammable non-aromatic organic solvent effective to produce a golden flame, said solvent selected from the group consisting of aliphatic hydrocarbons and yellow burning alcohols and mixtures thereof,
- water gelling agent comprising a polyacrylic acid and water, and
- microcapsules containing an aromatic solvent wherein said microcapsules have walls that are cross-linked and are double-walled and said walls comprise about 30% of the microcapsule weight, and the size of 50% or more of said microcapsules is 900-1200 microns.

A fuel composition comprising:
- 50% to 65% by weight ethanol,
- 2% to 15% by weight aliphatic hydrocarbon having an aniline point about 180° F.,
- 0 to 12% tertiary butyl alcohol,
- an amount of microcapsules containing a flammable aromatic solvent effective to cause a crackling sound when burned wherein said microcapsules have walls that are cross-linked and are double-walled and said wails comprise about 30% of the microcapsule weight, and the size of 50% or more of said microcapsules is 900-1200 microns, and
- a gel composition comprising water and a polyacrylic acid or salt thereof in amounts effective to establish a viscosity effective to suspend said microcapsules.
