Dirty Dozen Donation Derby: Stone Capped Containers

At Coronation, Konstantia sponsored a dirty dozen largesse competition. For my entry, I made a dozen small metal containers with cabochons on the lids.

Construction

The process began with cutting out a lot of rectangles out of sheet metal. They were then formed into ovals over a bracelet mandrel and bound with wire to hold the seam in place during soldering. When making any kind of circle like this, if you form the oval so the ends overlap then pull them back to form the seam, the ends of the metal will push against each other as they try to spring back into place and help you get a nice seam. The binding wire adds extra insurance that nothing springs out of place as the metal expands when it is heated.
After soldering, the cylinders are rounded back out over a round forming mandrel using a non-metal hammer (rawhide, rubber, nylon, delrin, and the like). Using a softer hammer like this ensures you don't leave marks on the metal.
Once the pieces were all rounded, they got cut about 2/3rds of the way up to form the lid and body of the container. Doing it from the same piece like this helps ensure the lid fits correctly and is not slightly too big or small.
At this point, the pieces get the tops and bottoms soldered on. I soldered squares on, trimmed the overlap with metal snips, then filed the edges flush. In theory, if you had a circle cutter the same diameter as your container, you could punch out the rounds and solder them directly. But I don't.
From here, the bottoms need flanges soldered in to hold the cap in place and the tops need bezels to hold the cabochons. The flange is just a thin, flat wire around the inside that forms a friction fit with the lid.
I skipped taking pictures of the bezels, since it is an annoying process trying to solder exactly on the edges of the caps. Needless to say, it got done, as well as some other lapidary work. To finish them off, the containers were all given a pass with a brass brush and pumice powder to create a satin finish. Four of the copper containers also got treated with liver of sulfur to darken them, making for four nickel silver containers, four bright copper, and four dark copper.

The stones used in the settings were hematite, rainforest jasper, tiger's eye, obsidian, lapis lazuli, petrified wood, and amythest, not in any particular order.

Fox Masquerade Mask

I've had the idea of making a metal fox mask for a few years now, but haven't really had a reason to do it until this year. Work decided our holiday party would be a murder mystery masquerade, which makes a great excuse.

The basis for the mask was Wintercroft's Fox Half Mask. The half mask is perfect for the masquerade use, and I thought the papercraft/low poly look would translate well to the metal.
I took the mask template and glued it to 22 gauge copper sheet with spray adhesive.
Then after about an hour of work with a jeweler's saw... I had the pieces, somewhat resembling a fox mask, but mostly a Batman logo.
The paper templates were attached to the other side, so I could use the dotted lines for initial bends. These were mostly done on the corner of an anvil or over a piece of 1"x4" clamped in a bench vice. A rubber mallet was used instead of a metal hammer, since the rubber won't leave indentions in the surface where the hammer strikes.
After the i…

Alan's Master of Defence Collar and Medallion

I was given the opportunity to make the medallion for Master Alan's elevation to the Order of Defence. I was told the theme he was going for was based around the Mary Rose, and generally the Tudor period. It was also suggested to avoid a leather based collar, although that was the preference of the person sponsoring him.
Design Mary Rose During my preliminary research, I did some looking around the Mary Rose museum's website, since they have a small sample of their collection online. I briefly considered doing something based off a boatswain's whistle (image #6) they had in their collection, since their description said they were used more as a badge of office instead of an actual whistle. It was also conveniently on a white ribbon already to contribute to the proper regalia. However, I decided this would be too small to be a recognizable medallion, and while amusing, difficult to use in a melee due to the masks.

I also sent an email to their collections department asking…

Queen's Prize 2020: Glassmaking, From Beach to Bead

For my entry into Calontir's 2020 Queen's Prize competition, I tried making my own glass. This entry won the Judge's Choice vote.

When I use glass in a jewelry or lampworking project, it comes in the form of preground enamel or glass rods. I tried taking a step further down the supply chain and making my own based on Theophilus' instructions, although I wound up modifying that glass so it could melt in my kiln and branching out to try other period compositions with modern materials.

Instead of trying to convert my documentation into a blog entry this time, I'm just going to directly embed the documentation I submitted with the entry, slightly edited to include reference photos that would have been part of my display.

Enjoy! If you have questions, feel free to add a comment.
