Based on two papers that appeared almost 30 years ago,(1,2) chrome tanning became more commonly used to tan leathers used for pipe organs because accelerated aging tests indicated that chrome tanning was more effective at retaining tensile strength. Anecdotal evidence over the last 30 years has indicated that the chrome tanned leathers have not lasted as long as hoped. Further, the atmosphere used in the accelerated testing used sulfur dioxide; and with the improvements in air quality in many parts of the world and the removal of many coal-burning ovens in American churches and their buildings, the reason for using sulfur dioxide enriched air is less justified. The work described in this paper reproduced the results of the tests done similar to 30 years ago, but we have also shown that using an atmosphere that is not enriched with sulfur dioxide yields very different results, namely that vegetable tanning performs superior to chrome tanning in terms of tensile strength retention.
