Hexagonal pentagonal ring / nut multifaceted ring Paying attention to the symmetry of the use of the basic metalworking forging technique of metal ductility, the process can control the width and the texture and create traces of the experiment. Based on the basic techniques, step by step analysis, how to use the metal plate bar, using the metal alloy process commonly used annealing forging technology, using the melting temperature difference to weld the solder silver alloy, the process can control the thickness of the narrow and the texture, create traces of hand and sensuality . The finished product is a handmade ring. Material: Brass Brass / Copper Copper Optional width: 3-3.5mm / 4-4.5mm * Prices vary by material and width. Please contact us for details. Learning techniques: forging hammer / welding / repair / polishing (Multi-angle ring lettering limit outer ring range) Course time: 2.5-3 hours * The above prices are for one person, only basic materials, course fees, space tools. Traditional metalworking techniques can also handle metal textures into a variety of styles: /calcined: burnt ancient taste / Full Bright: Mirror Gloss / fog quality: fog sand texture * If you want to make a more advanced style, or need more than 3.5 hours of production time, there will be another offer or a customized course service~ On the day of the course, the work can be done directly, and the price of the course is the production price of the single.
