Waiting

expression based on one of the book cats

A few weeks ago I got a studio request from my nephew and my sister-in-law. They've been reading Kevin Henkes' Waiting and my nephew really likes the cat shaped nesting dolls in the book.

They asked me to make them some nesting cats, which I have been calling stacking cats, though that's not accurate. The main request was that these cats be cute instead of creepy, like some of the sets they were able to find online.

my young assistant put this tail on the front. oops

I figured the cats would be fairly easy to make, which was true. I pinched the cats into shape and estimated the sizes, then cut them in half, added a gallery, and had my young assistant add some of the tails and ears. At this point I was thinking that this could be a fun project for my hand-building class.

Then I started working on the fit and realized that this was a completely inappropriate project for a beginning class. I also started to realize why some of the online cat options are creepy.

After getting the request, we stopped by the public library to check out the book. The cats are fairly simple in the book, but they have a slight narrowness at the neck (above the seam for the lid). They also have ears that stick up from the top of their heads, like cat ears do. What this means is that instead of fitting some simple egg shapes inside one another, I had to fit pointy ears inside narrowed neck spaces. 

tolerances are close with ears and necks

It looks like many other nesting cat makers chose to avoid the ear problem and paint the ears on, which adds to the creepy-factor. I spent a few days on the cat shapes, kept them simple and close to the shape of the originals in the book. I had to make some adjustments to size and my daughter decided that the interior cat should feel better in her cousin's hands, so that cat was made, by her, with flexible Sculpey instead of hard clay.

The cats are drying now, and will get some underglaze treatment after they've been fired. I'm hoping all my measurements were accurate and that shrinkage during drying and firing doesn't bring the tolerance too close for the Sculpey cat. All of the cats have pretty tight tolerance for fitting inside their pals, but if I allow a lot of extra space, the largest cat ends up really big.

PSA: Back up your images

In the culmination of a lengthy multi-week saga regarding my computer, the things I want it to do with it, and my inability to be patient with technology, I thought (for several hours and then overnight) I had lost all my images yesterday.

New images of newly fired first amendment cups--not lost.

It turns out that ignoring the problem for 20 hours solved it. The only missing images ares one I didn't actually take, but it reminds me that one should back up one's images periodically. The best time to do this, of course, is right after you terrify yourself by actually, or (one hopes) almost losing all your stuff.

I'm missing a good image of this piece and any image of it's partner. Both are now at Boxx Gallery in Tieton for their holiday show (opening this Saturday 11-4 during the Mighty Tieton Holiday Bazaar).

I remember a few years ago, I was in my office at work when the power went out, followed by groans and screams all up and down the office as faculty called out that they hadn't saved whatever they were just working on, along with a few relieved people saying they'd just saved. We probably all saved our progress regularly for the next few days.

I never successfully printed my design, but the kid used TinkerCad and hers printed mostly ok.
The problem I had yesterday had to do with updating my computer and updating iPhoto. A few weeks ago, I had to update my OS because I was trying to learn software for making objects for our 3D Clay printer. The software I was trying to use required an updated OS. So I updated the OS and spent the next week annoyed at Safari for discontinuing the bookmarks bar. Chrome's fine, but I use Chrome for Canvas and Safari for stuff like my blog and goofing around online. (I acknowledge that this may be silly, but Safari has my bookmarks.)

 I never did get the software that required the OS update to save correctly, but look at this dinosaur duck a student made.

Apparently I hadn't updated my blog in some time, because I also hadn't opened iPhoto in the new OS until last night. Once I opened it, I was offered an exciting opportunity to pay Apple more money for iCloud storage. I declined, then iPhoto proceeded to update? without any sign of progress for over an hour. After a couple hours, I thought there must be a problem, so I tried to investigate and was met with several alarming surprises, one of which being a pop up that said iPhoto is unavailable in my country, another being that when one searches for iPhoto or Photos in the App store, there are no results. IDK

Don't mock my pain, Apple!

After this glimpse at the terrifying possibility of losing all my photos, and realizing that if I did, it would be my stupid fault for not backing them up, I went to bed. This afternoon when I got home from work, iPhoto had updated (I couldn't look this morning because it would have ruined my day if it was still stuck on that mocking orange "Have fun with Photos" screen). So, all's well that ends well.   I'm going to back up my photos now.

There may be more cats in the future, Camden.

3D Clay Printer: First Weeks


This was our first "print." While the machine was priming it began to extrude and wouldn't stop when we "stopped" the "print" so I just caught the clay on a piece of paper on my hand, twisting as it came out.

Yakima Valley College Gets A 3D Printer for Clay

At last year's NCECA Conference in Portland, I saw a 3D Clay printer being demonstrated. I also saw a good deal of 3D printed clay at the conference, though I only saw one person (Brett Freund) who was using the printer in a really interesting way. But I thought the newness of the process and the fact that this machine prints wet clay, rather than liquid slip, which means that we could print, then alter the prints immediately, meant that there were possibilities for my students to be creative and really explore the unknown possibilities of this process.

Our first successful print came during a day when we worked at it for more than 5 hours, but only managed two successful prints total--and then broke the microSD card inside the machine.

After the conference, I submitted a proposal for my school to purchase a printer for our classroom. The proposal was approved quickly and we received the printer early in the fall. Of course I didn't anticipate that it would be that easy to get started. We got the printer, but the pug mill attachment was incorrect and we spent 5 weeks looking for a solution. Eventually the YVC facilities folks hooked us up and we were able to print for the first time at the end of October.


First Attempts to use the 3D Clay Printer

The first print that wouldn't stick. I can tell the machine starts too fast, but I didn't know that then, in part because the instructions and videos don't actually say how fast to print.


I took some videos of the printing process in October, but was feeling really frustrated because the clay often didn't stick to the printing surface and the extruded layers sometimes didn't stick to one another. I didn't understand why and had trouble finding out why from someone with experience. 


Our first successful print, stuck to the base, even though almost all the other prints needed a clay base prepare ahead of time in order to stick to the base. The company contact condescendingly told me that we should have had a piece of red constructions paper, and later, re-watching the videos I see where the paper was mentioned, but I still submit that a paper checklist with this sort of information would be much more helpful than videos I can't watch easily in my studio.


Since that first day, I've used the printer 4 or 5 days to print a variety of digital objects that came with the printer software, as well as some student designs. Of course it would be really helpful if I were just working with the printer during this time, but I was teaching class, grading assignments, helping students, attending meetings, and completing other full-time faculty obligations, so my time with the printer has been relatively limited. 


Troubleshooting & Trial and Error

The 3D Clay printer comes with no written troubleshooting instructions and minimal written instructions of any kind, including set up. The customer is advised to view online videos, which I did before setting up and attempting to print, but all the videos assume that you are more familiar with the process and 3D printers in general than I was when we began. I needed a list of definitions before I could even understand the videos.

Our second successful print on the first day shifted and leaned because the printing speed was faster than I would recommend. I can't say it is faster than recommended, because I cannot find any speed recommendations.


In our initial prints, we followed all the directions we could remember from the videos, but without much guidance as far as speed of the extruder, speed of the movement, or much of anything else, we mostly were just trying stuff at random. At the time, I wasn't sure that I would be able to figure out the issues without help from someone with experience with this machine. Now, however, looking back at the first video, it is pretty easy to see what went wrong at the time--it was printing too fast at the start. We've also learned that putting down a layer of wet clay for a base is usually essential.

This print was done on the second day, when the speed controls didn't appear to relate to the actual experienced speed of the print.

The thing I am not able to figure out is why the printer/software/file combination sometimes prints at a different speed using the same settings. You can hear me explaining the situation on the video to a student. This print is moving much more slowly than the previous print, but I'm printing the same file, the clay is coming from the same tube, minutes later, and the extruder speed and x/y movement speed are set at the same speeds as in the print immediately before this. The only difference is the actual experienced speed of the x/y movement is much slower.


A successful print on the second day, when the speed varied at random.

The machine seems to be working basically fine and is generally fairly reliable, but the support is difficult to navigate and frustrating when much time and effort is wasted--especially when I can't get much more than a couple hours at a time to work on it. I get the impression that the company is overwhelmed with the machines they are sending out, but they could provide much clearer instructions, troubleshooting, advice, and support--at least from this new customer's perspective. 

The second shape we printed requires some work after printing to open the closed top and open the negative space of the handle.

Students Figure the Thing Out

At NCECA last year, I had asked how hard it was to learn the online object making software. The woman at the booth suggested that the students would just figure it out. After making a few attempts to learn various 3D object making programs, and discovering that they and the tutorials are often designed to now work with a Mac (they keep directing me to right click on my one-button mouse), I was hoping the students would come through for me.

This student's design worked fairly well except for the open section on top of the leg. 

I opened up use of the printer to my students, letting them know that I am not much of a resource for the object making software. I told the students they could look into online tutorials for programs like TinkerCAD, but that I wouldn't be able to help. One student came back with a design she had made herself and it printed correctly on the first try and, to my surprise, the second. Then she and another student proceeded to print successfully or semi-successfully over the course of 2 days and 4 prints. There were some unsuccessful prints mixed in too, but fewer than at the start of our printing process.

This student design was also the first object to successfully print twice in a row. 

Hopefully soon I will be able to print some finished images of work and maybe even get some time to spend on the printer and software myself.

Come See My Work

The next two weeks are fairly busy with art exhibitions and openings, several of which feature my work.
my work at Boxx Gallery

First, this Thursday, November 2, the Maker Space Gallery is hosting paintings by Amanda Ontiveros. Opening reception at 6-9pm. Yakima Maker Space is on 1st Street between Yakima and Chestnut Avenues.

Amanda's work at Maker Space

You can see my work twice this Saturday, first at Boxx Gallery in Tieton with a reception from 11-1pm and at Larson Gallery in Yakima with a reception from 3-5pm (awards at 4pm).

my work at Larson Gallery

The Boxx Gallery show is called "What's on Your Plate?" and features works related to plates, eating, kitchens, and associated imagery and forms. I've got a completely non-functional plate sculpture and a wacky mug in the show. I haven't seen much of what other folks have.


The show at Larson Gallery is the annual Central Washington Artists' Exhibition, featuring a small sculpture of mine. Also showing at CWAE is Meghan Flynn, drawing and design instructor at Yakima Valley College. Her hyperrealistic drawing of rocks is worth checking out.


All three receptions are free and open to the public, so stop by and join us. Boxx Gallery is open on Saturdays from 11-1 and the exhibition is open through the end of the month. Larson Gallery is open Tuesday-Friday 10-5 and Saturday 1-5, except for Veteran's Day and the Thanksgiving Holiday. The exhibition closes December 2.

one of my mugs (soon to be) at Oak Hollow Gallery


Also opening next week is the Holiday show at Oak Hollow Gallery. I will have some mugs and bulbs for sale. The show opens November 7, but there will be an open house November 11. The show runs through the end of the year, but work is only there until it sells.

Decal Mugs

this mug is fairly big and bright, didn't photograph as well

Last week I applied and fired some decals on some functional mugs. Some of the mugs had decals over-fired previously, but some of the decals were applied to fresh mugs.

I made the mugs near the end of the summer quarter when I was testing out my new ball openers.

the Temmoku glaze works well on this slipped surface (no cat)

I was using some cone 6 glazes I had used last summer, as well as some new (to me) Potter's Choice glazes. I applied decals on most of the mugs, but skipped one with a lot of texture because I'm happy with the glaze on its own.

I played around with some wiggly bases

The mugs don't match each other, mostly because I was trying out a variety of different shaping and decorating techniques and was just entertaining myself.

I just like this bottom swirl, even if the photo is odd

I was especially happy with a few spiral trimmed bottoms which I highlighted with underglaze colors.

 
the cats worked better on the curved surfaces than other decals

The decals I used the second time worked very well, for the most part. The cats show up well in both gold and black on all of the glaze colors. 

this cat seems to be floating in space

I particularly like when the cats seem to be interacting with the landscape of the mug.

I like the way the cats use the line of the mug to stand on

Some of the mugs are less successful, in part because the glaze colors look a little odd in the second firing.

the cat shows up ok, but the color has become a bit metallic

I used mostly cat decals, but I had a few other science-y decals. These worked out less well, in part because they were applied on top of darker glazes and in once instance because they were incompletely applied.

the decal didn't completely adhere to the curved surface, and therefore fired off and out of round
It's tough to get the decals to stick well on curved surfaces, so after trying for a while, I decided to just try it out and see what would happen.

the mottled glaze color obscures some of the decal color

A few of the cat decals showed up with a line around the exterior of the cat. The line is where the clear part of the decal was cut. 

the edge of the decal shows up on this glaze

I cut them haphazardly because I thought the edges would be invisible--and they were on most mugs. On the darker, more metallic glazes, those edges showed up as sloppy outlines around the cats.

boo, hiss
The frustrating thing is that the fix would have been so easy, I could have simply cut the cats out closer to their edges, but I didn't and now it is too late. Maybe these are a good cups for someone with poor eyesight or a dark kitchen.

I plan to take a few of the mugs to Oak Hollow Gallery for the holiday show. The show opens in November and runs through December. I will bring some mugs and some bulbs, which will be sold individually. Let me know if you have requests, I deliver the mugs and bulbs at the end of this week.

Besides the mugs I made for the holiday show (well, I made them for fun, but some are going to the gallery), I also made a few smaller mugs with some clay that was recycled by my young helpers this summer. I used decals on these mugs, too, and the helpers each got their own mug as thanks for recycling clay with me.

I like how the cats seem to be playing in the grass on these mugs.

Decals and Firing


over-fired cat decal looks faded and dull

In March, when I was at the NCECA conference, I noticed lots of people working with decals, especially gold decals. I bought a few and tried some out this summer and fall. 

gold and black cat decal sheets with some of the cats cut out and used already

I wanted to try them and see if they'd be useful for students or for my own work. Unfortunately, when I bought them they didn't have anything attached to them that indicated the name of the company. I might have had a business card or receipt, but by the time I was ready to use them, I'd lost that. 

faded dull kitty

This sounds ridiculous now, but I looked up how to apply them, but somehow misremembered or misread the firing instructions from the seller or from the internet. I assumed they could be fired to a low bisque temperature, so that's what I did.

some of the over-fired gold cats cracked and shrunk (perhaps because the glaze melted a bit)

Perhaps surprisingly, some of them worked out ok. The colored decals seemed basically fine and some of the gold decals were ok, but others faded out to varying levels on different glazes or cracked and shrank on the surface.

Realizing I was doing something wrong, but still pleased enough with the good results to try again, I finally looked up the firing directions online. The company is Milestone Decals, by the way, and the application and firing directions are not hard to find on their website. The error here was all in the user and not the product.

Anyway, it turns out I had fired the decals much hotter than I should have done. Last week I received a small order of mostly cat decals to replace the ones I fired poorly. I layered some of the cats over the existing cats, though a few original cats look just fine. I bought both black and gold cats to replace the gold cats I had before. 

gold cat decal, over-fired but looking basically ok

I've got a few cone 6 mugs I made this summer and will try to get the decals on and fired (to cone 017, it looks like, not cone 08) this week. If they work out well, I plan to take some of them to Oak Hollow for the holiday show starting in November.
