I wanted to learn more about Landed's coloring methods so I did an internet search for him. It looks like he has been a gunsmith since 1946 and has trained several other gunsmith. One of them is Paul Johnston. Paul has a website (johnstonsmallarms.com) where he describes how Lander's trained him how to be a gunsmith. Paul also describes his case color process. He states that he uses an "acetylene" torch to color metal. He does not include any "chemical process". It seems clear to me that based on Paul's description that Lander's does use a torch to temper color actions. This is supported by the appearance of the colors on his guns.
