Jan Clouse started Carolina Lanterns & Accessories in July of 1999. The business specializes in custom-made copper and brass lanterns and lamps that use propane, natural gas, or electricity and evoke the elegance of historic Charleston. Clouse learned the business inside and out, including the characteristics of liquid propane and natural gas and the way gas lines are installed. She calls her business education “Gas 101,” a schooling she says has garnered her products good grades from homeowners, building contractors, SCANA Corp. and South Carolina Electric & Gas professionals — even architects.
