Matthäi Gutberlet Feller Schimmelpfennig Stübiger — Measurements of the light intensity of candles of different compositions

The aim of the investigations was to determine the light intensity of candles made of paraffin, beeswax, fat and stearin. In order to obtain evidence of the effectiveness of the combustion of these different candle raw materials, a measurement apparatus was developed, which makes it possible to determine wax consumption and light intensity simultaneously. The ratio (light intensity/wax consumption) of the two variables provides a measure of the effectiveness of the conversion of chemical energy into light.

Matthäi Petereit – THE QUALITY CANDLE

This article describes the raw materials and additives used for candle production and explains the combustion process in the candle flame. Based on the definition and classification of candles, it sets out the criteria that are essential for the safe use of candles, particularly in relation to people and the environment.

The design and content of a necessary European quality standard for candles are derived from this.

Determination of the soot properties of candles in production control

A semi-quantitative measuring procedure was developed to determine the soot emission of candles, which is especially suitable for quality control in production. The measurement is carried out in two steps: soot separation on a glass pane under standardised conditions, and photometric determination of the surface of soot precipitation in an integrating photometer (not available in english).

Matthäi Petereit – Candle Quality and the Future

The original English title of the lecture, held at the meeting of European candle manufacturers in Odense, Denmark, is “THE QUALITY FUTURE FOR THE CANDLE -A BURNING ISSUE”. This double meaning takes us straight to the issue.
