"Dogboning"

I enjoy making fused items, too. I made two plates for Their Majesties lunch at Fall Crown last weekend. I had an issue with the first one, and turned to the great people at Fused Glass Fanatics on Facebook.

The "not quite right" but serviceable plate, in the mold.

I was informed this is called "dog boning" and is the result of firing either too quickly or to too hot a temperature. After giving my firing schedule I was told the pre-set schedule I've been using goes about 100°, maybe 150°, too hot. I'm very glad to know this, and to know there is a term for it!

ODH Scroll for Baroness Zafirah

I describe myself as the worst scribe in the Midrealm. Frankly, I don't self-identify as a scribe at all. I don't work on any kind of C&I in my free time or for enjoyment. I started taking scroll assignments in my capacity as a herald to assist the scribes when a court list came out on short notice or was larger than normal. I've made 3 or 4 paper scrolls, unhappy with any of them, before deciding that I should try and make a glass scroll and play to a strength while getting the job done.

Still, I never take assignments above the AoA level, I leave those for the practicing scribes. So when Estelle, my good friend and our chief Signet messaged me on Facebook offering a Dragon's Heart assignment I balked. Twice. She was insistent, I'd really want this one. I finally agreed and was not disappointed. But that left me needing to figure out how to make a scroll worthy of our highest service award beneath a peerage, one going to another dear friend.

I started sketching ideas on my train ride and sent her a picture. She immediately liked one of the designs so I worked on making it into a full cartoon.

It can save a lot of frustration to make the most difficult cuts first, so I started on the heart. Slowly removed the "dip" in tiny cuts until I didn't dare press my luck further:


I painted on the lines with some fear. I've made one other Dragon's Heart (a suncatcher, not a scroll) and the green glass turned from a translucent Hunter's green to an opaque green with translucent mottled spots. I had one sheet of glass and it pretty much had to work for me to be done on time.



A sheet of lined paper from my previous scroll was sitting behind the lightbox, and it came in very handy with this. Once dry I did some stickwork to clean up the lines, and fired it overnight. I was intensely relieved when the glass came out looking as it had going in.

I was going to leave it alone there, as with the other heart, but I wanted to make it stand out more and thought of shading/highlighting schemes. I hastily mixed some paint, applied a mat, and tried several schemes for highlighting either the entire piece or the individual scales.


The left half is shading the entire heart (though not as gradually as I planned). The right half shows a stippled highlight, scrubbed highlight, a stickwork edge, and combinations.

I then decided this mat was a LOT heavier than I desired and redid it with something more like what I wanted in the "real" shading. My consulting scribe said she thought the scrubbed scale-by-scale highlight looked best so I did more of that on the test piece.


That being settled, I ground and remixed my paint better, and did the real thing. An observation about scrubbing is below.



The red and clear fill-in for the "inner circle" was easy and routine. I found a Spectrum Baroque sheet that had faint tan streaks and chose it for the calligraphy border for interest, rather than use more of the Foxtail sheet from the inner circle. This time I mixed up some water-based paint, after speaking with Kirsten about it, rather than the clove oil paint before. I tried the dip pen, but it fought me again. I finally tried a tiny brush from the local hobby shop, intended for painting Warhammer miniatures. I discovered that a pretty good technique could be gotten from it. A painting bridge was extremely important to this work. The calligraphy isn't great, but this time I've come away believing that with a bit of practice I could make some respectable lettering. The water-based paint made half the difference as well.

As always, click to see larger versions.


I was very unhappy with the way it looked foiled. The gaps were rather large. I suspect it's because I use photoshop to make my own patterns at times, and the lines are fuzzy. I think I'm sabotaging certain custom patterns right from the start by not having crisp cutting lines. I eventually quit trying to evenly space the pieces, and instead I pulled them closer to the center. This caused heavier lines and larger gaps between the heart and the calligraphy border, but at that point it looked symmetrical and pleasing to the eye, at least I felt so.

As the woman who taught me stained glass once remarked, "black [patina] hides all manner of sins" and once the roundel was completed I was much less upset with the finished product.



Lessons Learned
1) Water based paint
    After I made the Acorn scroll Kirsten mentioned she does her calligraphy with water-based paint for easier clean-up. I often remark that glass is a forgiving art for a shaky non-artist like myself because we can clean our lines up a fair bit. I don't have a before picture of the calligraphy for a reason, scribes would faint. I intend to use water-based paint to "calligle" going forward. I'm next going to try it with a "kistka" tool used in pysanky painting, another Kirsten recommendation.

2) Mixing from the edge.
    It's very difficult to keep a pallete of paint well-mixed with a tiny brush while writing. I found if I started aiming for the edge of the puddle it was easier. In this picture you can see the paint separating (It is my understanding the "grey" water is the gum arabic separating out). You'll notice the edges remain black. I started quickly mixing that small area when loading my brush. I can't be sure if this actually means I got very little gum into my paint, but I had no problems getting it to hold the glass until firing. 


3) Scrubbing
     I think I've remarked before that I love the look a hog bristle scrubber leaves on paint. There can be tiny lines left behind that look rather like a carved blockprint. It's an imperfection that is beautiful to me, and there are very few of those in this world. I started off using Q-tips to scrub out paint but that got messy. I switched to a bristle brush and enjoyed the look much better. The line between shading and highlighting is not as crisp and sharp but looks less amateurish to me. Unfortunately to get that effect I was very hard on the brushes, bending the bristles at the ferrule in a way you would never do a loved paintbrush.


4) Matting
     Paint does lighten-up by 20-25% after firing. The lighter matting paint I put down disappears in strong light. I took some pictures in my window, but direct light on a clear sunny day made the shading disappear totally. A cloudy day should show it as I intended, being similar to my lightbox. A darker mat (though not as dark as my first practice!) may have been better.

Book Hoard: Stained Glass Primer Volumes 1 and 2

While teaching "Glass Cutting - All Levels" with Molly at Pennsic, she mentioned two books she recommends for new glass artists, different from the one I usually recommend. I grabbed them this week to look over.

Stained Glass Primer (Vol 1): The Basic Skills
Peter Mollica
4/5
All around an excellent book, in my opinion. As Molly had told our students, it IS dated. He described, at depth, the creation of leaded panels, and gives an overview of copper foil technique. His glossary is worth a read in it's own right. The dated portions are the tools and chemistry (well, and the typewritten text); he uses tools that are very traditional, and I think most people learning today use newer versions (lead cutting pliers instead of a lead knife, for example). He also references oleic acid as a flux, which works fine but is greasy and hard to clean up. More modern chemistry provides fluxes that are much easier to clean. The technique was all good, however! I appreciate the fact that he prefaces the book with "There are many alternatives, but this is what works for me" in essence. A skinny but packed book, I read it in under an hour.


Stained Glass Primer (Vol. 2): Advanced Skills and Annotated Bibliography
Peter Mollica
4/5
Also an excellent book. This one covers painting and staining heavily (Me being me, I noticed his date for the discovery of silver stain was 100+ years late. Research is a LOT easier for me today than it was for him in the 70s though!). He covers actually installing your window, which I've never seen before and, frankly, has always been a mystery for me. I've never tried to fit an existing embrasure because I had no idea how to do it and no one seems to cover it. He also discusses reinforcing, saddlebars, etc that is of definite interest to a SCAdian glassworker. He gives a recipe for easel wax but I'm not going anywhere near it...

He has some interesting books in his bibliography. I look forward to ordering some of them, too! Have to make Amazon Prime worth it.

Texture...texture... the word even feels funny

I am a heavily color-focused person.

I love cathedral glass. It's what I work with 99% of the time. Opalescents lack something to me... it's almost like they are trying to deny their translucent, glassy nature. Don't get me wrong, they are beautiful, and I've spent considerable time drooling over Tiffany-era panels and lamps. But it isn't what inspires me and I rarely feel called to work with those glasses. Though, when I do, Youghiogheny cuts SO well for me. I really CAN appreciate them.

I recently made a small panel for my office, the first time in 8 years I've made a glass object for myself and actually kept it. I was focused, as I often am, on the colors. After staring at it for a few weeks I discovered some beautiful contrasts in the textures that I wish I could tell you were a conscious effort.



This is one vertical quarter of the Flag of the City of Chicago. The blue and red are two colors in the same texture. I'm not sure who makes it, but I intend to find out because it has a beautiful hammered effect in the sunlight.

I had originally chosen a Baroque clear/white glass for the white portions of the flag, because I was focused on the white content without wanting to use a truly opaque glass. I ended up not having enough and switched to a sheet of glue chip I had handy. After staring at it I'm finding that from almost any angle the dense glue chipping has an excellent "white" appearance that I discounted. The contrast between the glue chipping and the "hammered" blue and red gives a beautiful layered effect I hadn't intentionally designed into the panel.

I am trying to take this as a lesson for my modern work, to start giving texture the attention it is due, and not just the colors.

Grozing iron fun

Kendrick (THL Kendrick Cameron) made me two awesome grozing irons for my glass work. One is going to Lady Moll and I'm keeping the other, and hopefully we will demonstrate them during our glass cutting class at Pennsic.

I have previously written of the grozing iron I made, poorly, for A&S work. To compare, this one is MUCH easier, almost effortless to use. My "dremel" iron was much narrower and took more wrist force to chew into the glass. This is proper stock with a wider gripping face and more weight. I also noticed this generates a fair cloud of glass dust! Use under proper ventilation, outdoors, and/or wearing an appropriately-rated respirator!!

A quick video of me using my grozing iron:

Homebrew Lightbox

I've been asked a few times about building lightboxes. For ease of reference I'm putting my directions here. They tend to be pricey, in my experience, but I built mine cheaply in a college dorm and have never felt the need to upgrade (the want, yes, the need? No.)

It's not pretty but it IS strong enough for me to lean on the surface while I work and portable enough for me to haul to events and classes!

Two 1"x6"x4' "standard" boards - 3.49 each.
3-4 "24"x30" Clear Glass Sheet" -
1 2" aluminum corner bracket (Optional - I use it for aligning/holding the surface)
1 Sheet of plexiglass (lexan, etc).
1+ fluorescent "kitchen light" at Walmart (I use two 12" and 1 18", models that chain off one another)
1 white garbage bag
Mirror shards/aluminum foil (Optional)

Cut, or have your lumber yard cut, the two boards in half so you have 4 boards of 2' length. Assemble them into a box (I chose a "pinwheel" format where the end of one board butts the side of another). Once sturdy, if desired attach the corner bracket to one corner for aligning the surface. Place aluminum foil or mirror pieces along the bottom to reflect light, if desired. Place the light(s) inside the box and run the cord under the edge to your wall outlet. Place one glass sheet on the top. Cover with a garbage bag (can be folded in half or cut open depending on how bright you need). Place the rest of the glass on top, then the plexiglass sheet. The glass provides strength and the plexiglass protection (for all those times your glasscutter goes right off the edge of the piece you are working). Turn on the lights and you are ready to go!

Because of the location of my outlets beneath and behind my work benches, I bought a remote controlled power strip (~$15 I think) at Menards. This lets me turn on my lightbox (and by extension my grinder and soldering iron) without climbing around on the floor beneath my work benches. You know, where all the glass dust and shards fall. I strongly recommend them!
