Instructional Series. "How to hand-grind Soft Flameworking glass rods (COE 104) into Vitreous Enamel powder or Frit for Lampworking". Part 1

When I started my research and fabrication project last year on Late Anglo-Saxon Disk-Brooches, I began several different experiments based on my various theories. 

As I was doing my 1st millennium AD/CE glass and enamel research I did not come across sufficient published research showing a clear connection between the colored glass used to make Anglo-Saxon beads and the colored glass they broke down and used for enamelling. 

Just because something looks logical doesn't make it fact. To me it looks logical that the Anglo-Saxons used the same source of colored glass for both their glass beads and vitreous enamel work.


The following experiments were to see if colored Flameworking glass rods with a Coefficient of Expansion (COE) of 104, used to make glass beads with a torch, can be successfully used to make hand-ground Vitreous Enamel for kiln fired enamel.


*These techniques can also be used to make glass Frit of various sizes. Frit is used in Flameworking, Glass Fusing, etc.

I wrote 3 blog posts and filmed 4 short instructional videos on my process which anyone can follow in this order:

Late Anglo-Saxon Disk-Brooches. Part 3 (Enamel)

Then:
Late Anglo-Saxon Disk-Brooches. Part 4 (Enamel)

Then:
Late Anglo-Saxon Disk-Brooches. Part 6. (Enamelling Tools)

Part 6 of my series of blog posts related to my Late Anglo-Saxon Enamel Disk-Brooch project on the historical tools used in Goldsmithing and Enamelling from approximately the 2nd-century BCE until the middle of the 2nd-millennium CE. The Iron Hoods / Muffles and Trays used by Georgian Enamelers as well as those described by Theophilus in his Treates.


I recorded 4 related videos to show my techniques. The first and main instructional video:


This is the first video tutorial I've ever filmed and the main one to watch. (Length: 37m35s)

I am show my technique of dry hand grinding soft Lampworking glass rods (CoE 104) into 80 grit Vitreous Enamel powder.


Please click on the middle tab marked 'Description' to read any corrections on the temperature mentioned. Once it sounds like I say a different temperature and another I accidentally only said the second half of the temperature needed.


Then watch the following short videos that show the results from the end of the main tutorial.

The second video that compliments the main one. (Length: 0m57s)

This very short video shows what the washed, oven dried, and hand-ground enamel looks like right out of the kitchen oven. I've used soft Lampworking glass rods (CoE 104) as the glass source for my Vitreous Enamel experiment.


Then the next two short videos:

Third video to watch. (Length: 3m25s)

Fourth and final video tutorial. (Length: 2m15s)

Both show the kiln firings of the hand-ground enamel I've been making from soft Flameworking glass rods. You can see me extracting several small pieces from the Kiln to show the temperature color shift as the enamels cool. Photographs of them are in my blog posts.


Over time I will be adding blog posts in this series on my Blogger account and upload companion videos to my Vimeo page. 

I'd love to see what you do with your results of this dry grinding technique.

Wire and Bead Tutorials. Beaded Dangle or Pendant. Part 1

This is Part 1 of my blog post series of Wire and Bead Tutorials. In this post I will be showing a simple way to make a Beaded Dangle or Pendant using Head Pins and various Beads.

All of the following techniques and supplies are historically used and date back to at least the end of the first millenium BC (BCE) and continue well through the Byzantine Empire. I have found many extant examples from various times and places of the Roman Republic, the Roman Empire, and the Byzantine Empire. Over the coming months I will continue to look for extant pieces from other Mediterranean and European civilizations.

A modern Head Pin is a long wire with one end terminating in a flattened, round 'head' that is simiar to a nail's or some styles of rivets. They can be purchased at many bead suppliers or craft stores and come in a variety of gauges, lengths, and metals either precious or not.

1. Pass the Head Pin's 'end' (1b) through the Decorative Bead (1a) so its 'head' is flush against the bead's opposite opening* (1c).

2. Take 1 or more small Embellishment Bead (2a) and slide them onto the Head Pin (2 & 2b).

3. Bend the remaining length of the Head Pin about 90 degrees (3a) so that the Beads are secured in place and that there isn't room enough for them to slide back and forth. Use Round Needle Nose Pliers (3) to form a loop by bending the wire around it (4a). 

4. Use Wire Cutters (4) to shorten the Head Pin (4a), so it forms a closed, round loop (4b). Use a Pair of Flat Needle Nose Pliers (4c) to manipulate the loop so that it is centered and closed properly so there isn't any gap left. A gap could get spread wider through wear and tear to possible lose the Dangle.

5.  Pass the Dangle's loop (4b) either through the opening of the hook or brooch pin, or one end of a chain, cord or wire so it is secured.

* Please Note: If the Decorative Bead's bottom opening is wider than the Head Pin's 'head', then you can do any of the following historically used options:

A. First slide on a small bead, like a Seed Bead, that is wider than the Decorative Bead's opening. This smaller bead will stop the larger bead from falling off.

B. First slide on a spangle which will act like a Bead Cap. A spangle is a small, flat metal disk with a drilled hole at it's center, it is what sequince is made up of and it is used in decorative Embroidery.

C. First slide on a small Bead Cap with a hole small enough that the 'head' prevents it from sliding off the Head Pin. Bead Caps are usually curved like the Bead and look molded against it. 

D. Use or make a Head Pin with a wider 'head' or that has a balled up end with a wider diameter than the width of the Decorative Bead's hole.

E. Make a single or double Loop that's larger than the Decorative Bead's opening. Use the same techniques shown in this photo-tutorial.

F. If you are using round wire instead of a Head Pin, and the Bead has a small opening, you can simply bend the wire back onto itself (180 degrees) using a Pair of Flat Needle Nose Pliers (4c). This will form a closed 'U' shape that should be wider than the Decorative Bead's bottom opening.

Part 2 of this Blog post series will show how to make 1 style of Birka Grave Find, Bead Hangers. It is a decorative way to suspend 1 or more beads on a beaded necklace or chain. There are a variety of styles and I will be showing 1 of the 2 most found methods. This style of Viking Age Bead Hanger was predominately found in Birka Grave Finds.
