Heating Mantles are used to create an even distribution of heat, and they are used as an efficient alternative to heat baths and bunsen burners. When compared to both, heating mantles are faster, more efficient, and they provide a more evenly-heated surface area. Other methods can create "hot spots" on the glassware, causing unwanted stress and possible breakage. We designed our mantles with an insulated/cushioned lining, to create a gentle, even layer of heat across the entire surface your glassware. This in turn reduces stress on the glass, increases thermal retention, and minimizes chance of breakage.
