Two More Urban Flowers Burst Into Public View!

Posted by C Scheftic on 2017/07/13

I seem to be talking about a lot of events in Pittsburgh’s North Hills lately. And now that summer is really here, it seems well past any reasonable point to continue procrastinating about another event up that way which started in mid-spring.

The delay: I can find photos of only two (of the four) relevant pieces. I remember taking photos of the other two, but for some reason now can’t find them, haven’t found the time to really look everywhere both possible and impossible, so let’s just go with what we have!

Four of my pieces are (and have been since mid-spring, thus the selections & their titles) in a “traveling show” that is on display at the Northland Public Library through the end of August!

Two (shown here) are pendants from my Urban Flowers collection. Neither one turned out the way I’d originally intended. Both pieces ended up, instead, telling me what they wanted to be!

Urban Flower: Rainbow Bud Itopped with pollen) Urban Flower: Metro Daisy (small, red & clear)
Early Spring Bud
(aka Rainbow Bud with Pollen)
She Loved Seeing the Flower
Spring from the Pavement

I’d imagined the the larger, pastel-rainbow piece of glass going into a large flower. What with one technical issue after another, minor ones individually but still one after another of them, it ended up insisting it didn’t want to be overwhelmed by a lot a silver but, instead, to clearly be the focal point on a bud, just beginning to open, with a little bit of pollen just starting to appear. I’m OK with that.

The bezel around the red glass is exactly as I’d planned, and I was thinking I might use it on one of my other pieces inspired by Hepatica flowers. But I guess I hadn’t paid close-enough attention, because the flower-base I’d planned to use shrank just a tiny bit more than what would work with that piece of glass. It would have been relatively easy to “adjust” things to force all the pieces to fit. But I set the glass and bezel down for a moment to think about the best way to approach that fix and, when I looked up, I saw this flower next to them! Though I’d had other plans for it, I set the center-piece down and it fit in its space so perfectly that I said, “OK, if that’s where you want to go, that’s where you’ll go!”

The other two entry pieces on display (the ones with their pics missing) are movement-earrings: not the ones with layered elements that I call spinners that rotate around a horizontal axis, but the ones I sometimes also call spinners but also refer to as having movement that will rotate around a vertical axis.n Those links don’t go to photos of the pieces in the Northland show but, instead, the second one links to a different pair from several years ago with a comparable mechanism.

It’s been so much fun making all of those (and more in those series) that the seasons have seemed to be speeding by! What about you this year? Please let me know in the comments! Should any of my (local) readers find themselves in that area, please do check out the show and let me know that too!

Summer Solstice, Raku Party, Artisan Market

Posted by C Scheftic on 2017/06/21

I am really looking forward to the way the North Hills Art Center will celebrate the Summer Solstice tonight … with the opening of their Summer Artisan Market and a Raku Party!

I still have a couple dozen pieces left of the huge batch of Raku pottery I made at IGMA: the video above shows details on a random sample of a dozen from that lot.

Several weeks ago I made a bakers-dozen new pottery pieces out of raku-friendly clay. They’ve since been bisque-fired, so they’ll be ready to put through the Raku-firing process at the party tonight! None of those are like ones in the video: I didn’t want to assume that the set-up there would be appropriate for that particular kind of piece (if you didn’t catch the video when I posted a link to it last summer, check it out now to see what I mean!), so the ones I’ll be firing tonight are items for use in my studio, as I do my own work or by students during classes: a mix of dohgu oki (for tool holders as I work, though these are a bit larger than the hashi oki I typically repurpose that way) and small vases (for tool storage, between sessions). This may well be a round of “no two alike” pieces, where I take advantage of the opportunity to explore the range of new-to-me glazes that will be available tonight.

Three Rivers: Metro MixIf you have never participated in a raku-firing before, know this: Most of the time, when potters or metal clay artists talk about firing something, they refer to loading up a kiln and then going off and doing something else until it finishes. But Raku is not like that! There is a brief period of waiting but, mostly:

Raku reminds me in some ways of torch-firing a piece of metal clay, with smoke and fire, and lots of fun things to observe, and ooohs and aaahs as you get your first glimpse of the firing results, and even more fun once each piece has been brushed / cleaned up.

And, yes, if you’re hesitant, you can observe the smoke and fire parts from a distance. Me, though, I want to be close to the action!

Oh, and there will be lots of action in addition to the Raku-firings. The opening reception for the Summer Artisan Market means there will be snacks and beverages for folks to enjoy while checking out a range of great hand-made products from local artisans. Those wheel-thrown pottery pieces of mine that I mentioned at the top of this post –– on a scale suitable for a doll house or faerie garden –– will be available, along with lots of regular-size pottery from others.

A few of my Urban Flowers and Three Rivers pendants (another new one of the latter is shown with this post), and many more of my styles of neck- and ear-wares will be available. (I really need to remember to take photos after I’ve completely finished assembling my pieces: they do come hung and all ready to wear!)

2015_11_FiveCardHolders_OneGearBusinessCard_PB241207So will dozens of my colorful glass card-holder ornaments! I sell those at the holidays as pieces that can be hung on a tree but, of the ones I’ve kept for myself, I never put them away at the end of that season. Since I’ve decorated then in a whole range of different, bright colors, I weight them down a bit (filling them with rice or lentils), stick little notes, reminders, instructions, or photos in the double-loops on top, and use them to spread bits of cheer around all through the year..

For my local readers, I sure hope I’ll be able to celebrate the Summer Solstice with some of you tonight! If you’re not able to make it for all that fun, but would like to shop at the Summer Artisan Market, it will be open when the center is open through July 8.

Exploring my “Urban Flowers” Series

Posted by C Scheftic on 2016/10/17

This post is going to jump into the middle of a story about several different things I’ve been working on: adding a little bit of color to my creations by incorporating some glass (especially dichroic glass) and working with sterling silver metal clays.

Why start in the middle? Well, I really do miss writing about all the explorations I do in my studio. I haven’t been saying much about them lately because we still don’t have reliable internet access in the building … and I used to compose posts as I worked. You can probably imagine that, after a long day of working on explorations (and more), the last thing I want to do is go home and stay up for hours more writing from there. But it’s a gorgeous fall day and I suddenly decided to enjoy it by staying home this morning, sitting out on my back porch with a cup of tea, and writing about a piece I just finished on Friday.

I will provide a bit of background:

The second, or maybe it was the third, piece I ever made using metal clay incorporated a lovely, long, oval, pink glass bead, set with loops of syringe-clay to hold it in place. It was fun to do, but it took me a few more years before I got into adding glass on any sort of regular basis. About six or seven years ago, I went through a phase of using glass fairly often. Then I moved off in other directions, with what remained of my collection of glass pieces sitting in a corner of one of my stash-drawers. I’d acquire another bit of glass every now and then until, a few years later, I made a few more pieces using some of those, and taught it as the final project in a couple of private lessons and multi-session intensive workshops.

ProjectSample_Glass_SwirlGlassInFineSilverProbably the main reason I didn’t keep pushing with glass is because I’d felt limited to using PMC3 or Art Clay 650: those were the only metal clays that could reliably be fired with glass. Now, those are both fine metal clays: I have been quite happy using either one of them. But glass just isn’t happy at the 1650°F (900°C) for two hours that all fine silver clays require for the strongest sintering, even with those formulas. Although they will technically sinter at lower temperatures and shorter times, they still don’t get as dense, and thus won’t get as strong, as they could do at 1650°F for two hours. They do come out perfectly acceptable, and I hope people will treat any piece with glass somewhat gently … but I just like going for the strongest pieces possible.

Still, I do love glass. So this summer I made some more fine silver pieces with dichroic glass cabochons, called them class samples, and included that process in another four-day session I was scheduled to teach at The Artsmiths of Pittsburgh. The first photo with this post shows one of the sample pieces I made for that class. While a couple of my samples used the same PMC3 and Art Clay 650 that I’d used in the past (mostly to refresh my memory of how I’d done it) this one and several others used PMC Flex. Flex is similar to PMC3 but it has a slightly longer working time (good for workshop students not yet comfortable enough with metal clays to work really fast) and it remains a bit flexible when dried (which makes it very useful for anyone fashioning the parts that capture and hold the glass). And, though there’s still the problem of not sintering to the maximum density possible, it does sinter reasonably well at temperatures where glass remains happy. So, for fine silver with glass, it seemed a good choice.

Urban Flower #7 (Blue Lagoon)Now, at last, on to the Urban Flowers explorations:

After I’d made those samples, on some of the hottest days this summer when I just didn’t feel like going out to work in my garden, I got to thinking about a possible new series of pieces, ones I’ve taken to calling my Urban Flowers. They are flower-like designs, but from my imagination. While they may be based on some actual flower varieties (and may or may not be named for their inspiration), I am not attempting to make biologically-accurate representations. They’re just a city-girl’s dreams. The textures come from urban life: wallpapers, flooring, construction debris, household objects, etc., and they feature glass (or, occasionally, something else that is commonly found in urban environments).

Urban Flower #5 (Purple Haze)I’d been happily exploring these designs, mostly using PMC Flex, while working on some other styles completely and, for those, using diy-960 clays (i.e., mixing PMC+, PMC3, PMC Flex, and/or Art Clay 650 with PMC Sterling clay).

And then CoolTools released EZ960. OK, I didn’t really need it, as I’d been doing fine with my various diy-960 combos, but why not give it a try? Soon after, both PMC and Art Clay released their own silver-rich sterlings (PMC One-Fire Sterling, a .960 formula, and Art Clay 950, where the number designation has switched from a minimum Celsius firing temperature to a Fine Silver percentage). I got some of each of those and started testing them too. At some point, I hope to find a chance to write about all that testing. For now, though, let’s stick to the Urban Flowers story.

While I do love the color of plain fine silver, I can also appreciate the gain in strength that it gets when a bit of copper is added to produce sterling silver. And, as noted above, I much prefer to produce pieces that are strong. The 950-960 formulas will be stronger than a 999 fine silver; they get you to almost as much strength as you can get in the great 900-925 alloys. Plus, they have the benefit that they are as easy to fire as the 999 clays (i.e., much easier than the 900-925 ones, where having more copper complicates the firing). So, yes, any 960 (diy or commercial product) will be a compromise, but still an excellent choice.

With one exception: the 950-960 clays need temps and times higher than glass can take without just melting.

But, d’oh, why didn’t I think of this before (even with the .999 fine silver clays!)? I work with base metal clays, and I do some pottery, and we’re talking about multiple firings to get many of those to work. So here’s the inspiration I had, and the first (simple) piece I made to test it out….

I made an Urban Flower base out of EZ960: the petals, the stem (if included), the bail on the back … everything but the glass and the bit that holds the glass in place. I fired all of that according to the schedule for 960, to achieve maximum strength. Afterwards, I positioned a glass cab, surrounded that with a .999 fine silver washer shape to contain it, made sure that was well-attached to the already-fired petals, and fired the whole thing again at a schedule that worked for just the “bezel” and the glass. After a bit of tumbling, polishing, and patina, voila! It may not be perfect, but I am really happy with this result! (Though both the silver and the glass are brighter in person than they look in this photo….)

Urban Flower No. 8 (Gold Cinquefoil)

What do you think?

I do still need to figure out a reasonable pricing schedule to accommodate the fact that I’m doing two firings, and that attaching the unfired clay to the fired metal can be a little trickier than attaching two unfired elements. Though that will add a small amount, in the grand scheme of things, it won’t be much. Once I’ve found time to make more to extend the series, and refined the process of doing it this way, I can see how the time works out and apply that even to my initial-trial pieces too. The only real problem with this approach is the way the two firings will affect trying to do this in a class … but it’s just another reason to offer multi-session workshops, rather than the quick one-shot ones, when including easy but still advanced topics.
