Mar 21, 2016 · If the brass has been held at just the right temperature to anneal in say 5-6 seconds, then once removed from the flame it will cool out of the annealing temperature zone rather quickly without a quench. It will be too hot to handle with your fingers but annealing will be over and done. The brass will not go back to a harder state on its own.

Per Grimwade, in practice, if annealing is done in a furnace, the recommended times are typically around 30 minutes. Torch annealing at the bench requires slightly higher temperatures because times are much shorter. Before annealing silver, copper, brass, or …

Oct 26, 2011 · Annealing is the process of heating a metal to a specific temperature before it’s worked on. Through this process of annealing, the precious meal is softened and made pliable. This will allow you to shape the metal into the jewellery piece you want. You might need to repeat the annealing process in case your metal work hardens.

Nov 27, 2019 · Annealing brass is very similar to copper, although the temperature should be a little cooler. What you are looking for as you apply the flame of your blow-lamp/torch onto the part to be annealed is the tell-tale colors again. When the brass starts to show a blackened color, then is the time to quench it quickly before cleaning it up.

Feb 20, 2019 · The higher the annealing temperature, the shorter the time required to anneal. The grain structure of the brass begins to change - indicating the start of annealing - at just under 500 degrees Fahrenheit. At 600 degrees F, brass will anneal in one hour. At 800 degrees F, brass will take only a few seconds to anneal.”

Dec 24, 2013 · From the article on 6mmbr.com "The critical time and temperature at which the grain structure reforms into something suitable for case necks is 662 degrees (F) for some 15 minutes. A higher temperature, say from 750 to 800 degrees, will do the same job in a few seconds." 750 degree Tempilaq is what you want.

Feb 06, 2018 · In general, annealing should be completed in a time that is measured in minutes, not hours. Metals can be softened to a certain point and no further, regardless of how long they are exposed to elevated temperatures. Generally anytime you heat a typical jewelry alloy to a red color (above 1050°F) the alloy will begin to get softer.
