Soldering Perfect Prong Settings

Course Description

About this course

In this virtual course, students will learn how to fabricate their own prong settings, using a torch with two direct gases (oxygen/acetylene or oxygen/propane), and how to then prong-set their stones appropriately. Strong emphasis will be placed on torch temperature control, as well as flame placement. Students can expect to gain knowledge, strategies, and confidence to make both calibrated and free-form prong settings in this technical workshop.
