Wendy-Thanks, I think your posts are the best. I owe you allot already for providing such good guidance.

Today I am really happy to be finally able to post more work. The following photos are just a few points taken over several weeks. I didn't want to share anything until I knew that I had a working mold.

I actually injured myself over the memorial day weekend (pulled hamstring, broken elbow, bruised ribs...yeah, a real train wreck). This has slowed the process...but today I am finally able to share some of my work.

First, an experiment making a model and mold using oil clay...
I got some oil clay at a local craft store so that I could try out making an original sculpt from a block of it. I had to buy it in small chunks and when I opened the small packages, I found that the oil clay was quite hard and not easy to work with. So I put it on a pan covered with tin foil and stuck it in the oven at 200 degrees for several minutes and it turned to mush in no time. I was able to combine it all into one big block once it was warm very easily, which is a step I would highly recommend. However, I would recommend putting it in a small glass bread pan or one of those rubber bread molds you can put in the oven before hand just to avoid wasting oil clay like I did (hopelessly stuck to tin foil).
Once it started cooling down, it was really easy to work with for quite a while. It only hardened back up after sitting overnight.

So here is the oil clay sculpt I did with the intention of making a mold afterwards...Yet another moai.



And here are pictures of the first cast from the mold (post initial clean up)





The hardest part of making this mold was getting the angled top right. The actual cast line moves from the midline of the ear (at the top of the ear) to the top of the forehead. This was so that it could be removed from the mold. It had to be planned ahead of time.

Lessons learned with this mold:
1.) I would have put on 5 layers of mold soap so that it would open up easier. (with the weird joint lines, this would have helped)
2.) I would let the mold dry longer before opening it up (lost a chunk of the base plate)
3.) I would have dried the sections strapped together after washing off the mold soap (there was some warping, the mold leaks and needs to be sealed because of it)
4.) I need to think about how to better make the transitions for the base plate and pouring cone at the top and bottom (large seamlines there)
5.) I would suggest 1-1/2" of cover vs. 2 or 2+ as the molds get to heavy to move.
6.) I would have made the top of the head wider so that the opening at the top would be bigger after firing. It may be OK but I wont know until after I use the mug a while.

I will post this one again later and try and give an idea of scale.

That's a unique Moai. Good job and good hints. I always open the mold the first time by using the salad chopper and a rubber mallet. One whack and the mold is good from then on. The mold does have to dry completely before the first cast or it does from that point on fall apart.

I'm looking forward to when you glaze this one.

Back to your post. You broke and elbow? Were you roller skating? That's horrible. I don't see how you are doing anything at all. Best wishes for a speedy recovery.

Wendy

Wendy - I was playing basketball with the neighbors during a bbq on memorial day weekend. I was running so much that I pulled my hamstring and then took a hard crash on the pavement. Not pretty and I'm still struggling allot to keep pace with the demands of life. It'll be 6-8 weeks of time for the bones to heal and probably as many weeks in physical therapy. Luckily I have a desk job, so going to work is easy.

It's hard to pull the plug and hold off because I have a commitment that I need to work on...I am working on a Limited Edition Mug for the local tiki bar in Edmonds, WA right now. The owner would like to have them this summer, so I am sort of committed to making it happen injury or no injury. If I get him 10 now, that is all he is looking for. I also have one other person that has requested a mug

Speaking of that...here is a photo with both mold mugs...



I will post more photos of Taki Tiki #2 a little later...

Aloha all - Posting photos of the mold making for the larger Taki Tiki. This one is being made for a local bar in Edmonds called the "A Very Taki Tiki Bar and Grill" in Edmonds, WA. It's our local tiki bar and part of the inspiration for me starting to make Tiki art in general. Several months ago the owner Brian and I had a conversation about tiki mugs in general and we found out that we both had a common interest in it. Over time we spoke more about how things were going and the idea of making a mug for the bar came up somehow. Anyways, I was planning on the first mug being for the bar...until after I learned about double shrinkage the hard way (original carve shrinks as it dries, you cast it, and the slip cast shrinks again). Anyways, once he asked me if I could do 10 mugs just to see if the loyal customers would be into it, I accepted the challenge and came up with a new mug design that was loosely based on the first. I was also inspired on the Cannibal mug idea that Wendy Cevola put in my head some time back...

Anyways, enough of the storyline. Some photos of the bottom half of the mold making are attached. Mainly I took these photos to show the build up technique in casting the first half of the mold. I did this same construction with a bottle mold and had a blow out disaster that required me to start over, so I would definitely recommend that you take the time to assure that the object is both fully sealed and supported the first time. It worked just fine the second time when I was more attentive to those details. I think I am going to give Wendy's idea of foam blocks a try once I run out of foam board. Oh, and get the foam board that has the smooth, sealed surface if you have the choice.

Here is how I supported the carving...with a wood block, foam pieces, and tape.



Then I build up the foam board build up platform. There are foam supports underneath the main platform. The platform height was set between 1/4-1/2" below the mold joint line I marked on the carving.



This next photo shows the clay build up on top of the platform to the joint line, the pouring cone at the top, and the base mold area at the bottom.



From this point, I made keyways/registers around the edges. I set up my cottle boards to pour the bottom half of the mold and sealed the board joints and perimeter edges with clay. After pouring the first half, I built up the top pouring cone and bottom base plate again and put three coats of mold soap on the plaster areas. I again sealed the boards and perimeter areas with clay to seal them and poured the second half.

The resulting mold looked like this...It's sort of a heavy monster (another lesson learned?)...



I wish we lived in a dryer climate. I let the mold dry for two weeks indoors (where there is heat) and I'm not too confident that it was as dry as I would have liked it to be. I think in the future I may want to bring my molds into the workshop to dry. The kilns make the room very dry and is probably a better place to let them cure. Wish I lived some place dryer like California or New Mexico...or maybe I just need to get a kiln.

And finally, photos of the first casting out of the mold after minor trimming (needs clean up).





The mug is still rather large...so I am hoping I didn't overshoot with my sizing. I will only be able to tell after firing. Wish me luck?

Mahalo for looking.

Great day here in Seattle...it's been about 80 degrees for several days and were all loving it up here. Best part is the ceramics are drying much faster than normal...which helps. Here is a photo of some of the Taki Tiki mugs drying. The one on the right has been drying for about 4 days, the one in the middle about 2 days and the one on the far left was taken out of the mold yesterday. It's cool to see the difference setting the three of them together side by side.

Aloha,
It's been pretty busy this summer...not allot of time for posting. The efforts on the mug making are coming along well enough for part-time, part-time work. Last night I dropped off 10 of the Taki Tiki mugs for firing. Picked up the first three from firing. They just had an arts festival in Edmonds so the place I do my firing out was down for a week. That being said...I was able to pick up a few things...


The Taki Tiki 2.0's came out about the size I had calculated (roughly). I took a photo with them lined up next to one of the Tommy Bahama mugs for scale. Once I go to wash them out (get any loose ceramic removed), I will check the final average volume. They are on the larger size...but I like the wide opening...it's so much easier to fill with ice and pour drinks into...Plus allot of surface space for garnish.



Pictures of some other Taki Tiki 1.0's in various stages of glazing...


a picture of the Ku mug I posted earlier...


and finally (posting on the regular thread as well), the enchanted tiki room chalice survived the kiln!!


Now...lots of glazing, test tiles, casting, etc. Much work still to go...but it's fun finally getting some fired pieces back.

Mahalo for looking.

RV

I had some catching up to do. Reading and looking at all the photos was so much fun. I'm happy that it's all going so well for you.

I worked my way through college as a dental assistant and those teethy tikis make me think of those days.

The Swap goblet is what everyone is hoping to trade for, it's wonderful.

Cheers, Wendy

Wendy - Glad you liked checking out the posts. I still read yours as often as I can. Love what you've been doing this year. If you ever want to collaborate or just shoot each other ideas, you know I'm open to it.

Thanks for the complement on the goblet mug. Yours is every bit as cool. Everyone so far is doing so well. I am proud of the tribe.

Hang10- thanks bra. You da man. Love the trip photos. Look like your working on a tiki bucket list most of the time.

Posting some more progress photos of the ETR chalice here...The photos are right at the completion of glazing. Working on this project and production of the Taki Tiki Mugs right now....Lots going on. Will post more of the Taki Tiki once I get some glazed and fired. Thanks for looking.

Just a quick post today...

Some mugs waiting to be glazed.


Need to meet with the owner of the Taki Tiki to see what color mug he wants and how he wants it finished. Did artist proofs of three brown colors...we will see which one he likes.

Decided to make a few raw versions of the two Taki Tiki mugs...both are going to have a "volcanic glow" glaze interior.


If I have time before Tiki Kon, I will post more photos in a day or two. Put a few things in for final firing last week.

As always, Mahalo for visiting.

RV
