Making a Slipcast Mug pt5: Production Slipcasting & Edition Numbers - Tiki Technical Tuesday

[@wesleydelvalle6197]

Thank you for giving these master classes for free! 💛

[@vantikistudio]

Thank you for watching! Tell your friends!

[@gediba]

I've been watching your videos for over a year and only now I took a better look at the numbers. You deserve a lot more views and subscribers. All of the info is so invaluable and presented in a perfect way.

[@vantikistudio]

Thank you! I’m happy with my channel growth - at the start of the pandemic I had about 200 subscribers 😁 Be sure to tell anyone you think may enjoy it about my channel 😅

[@darenot2128]

I really appreciate the detail and effort you go to in these vids and the info you give. Great work.🤩🤩

[@vantikistudio]

Thank you! I appreciate your viewing the episodes!

[@jfvanwijk]

A slip farmer, haha! Perfect way to phrase it. Thank you for making all of these videos. They've been invaluable to me (and many of my friends at the local pottery studio).

[@vantikistudio]

Thank YOU so much for watching!

My dyslexia kicked in and I read "Opening & Screaming". I was wrong, but you probably know the feeling. I so appreciate these tutorials. Through your videos, I got hooked on the mugs, the techniques, and the creativity. Thank you for all the extra work you put into these videos. Mahalo

[@vantikistudio]

Mahalo for watching! Sometimes I do scream when opening 😂

[@joaquinsalgado3567]

Amazing video as always, thank you for documenting the whole process so thoroughly. A friend of mine and I always watch Tiki Technical Thursday on our lunch break at work. Greetings from Argentina!

[@vantikistudio]

Thank you so much!

[@johnp2773]

So good. Had a thought. Ever think about putting some mugs in a wood or salt kiln? See what craziness comes out?

[@vantikistudio]

That would be awesome! I just need to find a wood salt kiln! 😅

[@SullivanOwen]

It's really interesting hearing about your edition process, I think about photography editions most when it comes to numbered works. I'm working through my own process in terms of my own editions and molds, I'm making far fewer pieces (say 5 with a max of 20) and don't feel done with all the pieces yet. I'd like the option to explore other glazes, finishes or manipulation so I'm archiving the master molds and will be clear about that during any sale. My sculpting process for the positives is also taking the better part of a year so I'm not sure I can be done so quickly with each piece but as my other work is in flowers/weddings I completely understand how cathartic it is to trash something and feel ready to move on to the next challenge!

[@joyg2526]

Your attention to detail is boggling my mind, that's craftsmanship. Question: what do you do with the plaster remains? Are they biodegradable? Can they be buried or used in another way? Just curious.

[@vantikistudio]

The broken up plaster goes to the landfill. It is gypsum, a naturally occurring mineral rock, so I don’t feel too guilty about putting it back into the earth.

[@jonconrad1093]

So much fun.. So much love

[@vantikistudio]

Thank you!

[@shillingv6289]

Amazing video! And I love your positive vibe)) just found today your channel and have sticked to it, great job! I run jewelry workshop in Portugal and I'm very familiar with your ideas and feelings when I'm doing the work. Thank you!

[@vantikistudio]

Thank you so much! I’m so glad you found the channel!

[@craft-o-matic399]

Fantastic! Can't wait for glazing! Get well soon! Lisa

[@vantikistudio]

Thank you!

[@eliaswatts556]

Your videos teach me so much!! Thank you for the educational and entertaining content :) And art!!

[@vantikistudio]

Thank you!

[@Kamahaku]

I live for your videos!!!

[@vantikistudio]

Mahalo!!

[@warnermcgee8856]

Thank you so much for continuing the TTTuesdays. They are very enjoyable to watch! I don’t know how you find the time to make these videos. Currently your shop seems to be down or being updated. How would one purchase your mugs? Is there a waiting list? I’m sure pricing varies across your designs but what would be price range of your pieces? Keep up the fine work!

[@vantikistudio]

Thank you! We don’t currently have any mugs available. Your best bet it to keep an eye on my Instagram and Facebook feeds. I post sale announcements there.

[@JohnJones-oy3md]

Love watching the production process. Something tells me this is not their first rodeo. LOL

[@vantikistudio]

😂

[@CurtisBuhr]

Really enjoy your videos. I'm curious if you've ever tried getting extra fancy and building a sort of spout into your sprues for cleanly pouring out the slip? I'm thinking something like the Pyrex measuring cups have.

[@vantikistudio]

I know folks who have - I just find having the well built into the mold to be easier for me

[@JohnJones-oy3md]

20:12 - Thousands of years from now geologists will be trying to figure out the origins of a large gypsum deposit found in Oregon.

[@rudolf275]

What is the brand of your green wire glasses?!?!? they are super!

[@vantikistudio]

Thank you! They are SUPER comfortable and weigh next to nothing! They are made by Lindberg

[@rulasalsa]

I love the perfection in your work I have a question,where do you dispose the molds?

[@vantikistudio]

The plaster bits go to our local landfill, and the silicone masters I cut up and recycle in new molds.

[@theartisanshop1055]

Great job 👏🏻 Would like to buy an slip table 🤞🏼 can you share more info about yours 🙏

[@vantikistudio]

Sure thing! It’s a Big Puddle by Glaser Ceramics. It goes in and out of production. They also have a smaller version called the Lilly Pad glaserceramics.com/equipment/lily-pond

[@benji405]

Another fantastic video! I learn something new in every single one! Do you make the 20 moulds you know you’re going to need all at once or do you start with 10 molds then make the other 10 once you’ve cast half of the edition?

[@vantikistudio]

I just do 10 at a time - it it a very physical process, so after a week of mold casting I’m ready for a break. I’m casting the second group of 10 molds this week.

[@remibertrand5990]

Nice process ! Why is it that you only cast once a day and not twice ?

[@vantikistudio]

The molds need time to dry out - they absorb a lot of moisture in the casting process. Here’s a deep dive: kzbin.info/www/bejne/aKW4Z6Z4eZ6llas

[@geneard639]

Is there any way to recycle the plaster or silicone molds?

[@vantikistudio]

For plaster, no. I’ve been told by master mold makers that there was a time in the golden days of Hollywood when sets were made mostly of plaster that you could recycle it, but sadly that isn’t the case any more. The good news is it is a natural mineral, so I’m not adding anything toxic to the earth. I do recycle all my silicone molds - you can see how here: kzbin.info/www/bejne/Z2O4kpuCqpKBj9k

[@lit_louis6017]

How does the editions process work for seconds or bad firings? Say mug number 176 / 350 fired poorly in the kiln and had some glaze defects. Do you destroy that mug and make a new 176 or do you sell as is, or destroy it and then not make up for it in the total? Do you always end up with 350/350, and if so how do you deal with defective pieces?

[@vantikistudio]

At the end of a run, I will cast 2 or three mugs and leave them on the drying rack unnumbered. If the edition goes through the glaze and firing process smoothly, I destroy the unnumbered castings. If a mug fails in the glaze firing, we bother the number and mark it on one of the unnumbered castings. We always release the entire numbered edition.

[@canorth]

How long do you dry them? I made my first slip mold today and wanted to purposefully go a little too fast to see for myself how much that’d fail, so I took a fresh, small piece, just out of the mold and put it in my oven to dry. 170 degrees for maybe 40 minutes and then straight to 400 degrees. The 400 degree jump made it explode.

[@vantikistudio]

It depends on the weather where you live. I let mine sit on the drying rack for 4-5 days. A simple test is to hold the piece to your cheek - if it feels cool it still has moisture in it

[@canorth]

@@vantikistudio finally, an advantage to living in Utahs dry air.

[@craiggordon2502]

What do you do with the busted molds as it relates to recycling? I assume you use the silicone cut up as filler for other molds?

[@vantikistudio]

I do indeed recycle all the silicone. The broken up plaster molds go to the landfill. They are gypsum - a naturally occurring mineral, so I don’t have to have the added guilt of toxic materials 😅

[@craiggordon2502]

@@vantikistudio cool I wasn’t sure about plaster that’s cool to know. Love the channel. I’ve learned a lot

[@bobonono8544]

Thunk you so much for this video ❤️❤️ I have I question...can i cast metal in a slip ceramic mold ??? And how much heat it can take ??? I watched some videos of people casting glass into ceramic molds but not molten metal!!! Again thank you 🙏🙏

[@vantikistudio]

Thank you for watching! You can’t cast metal into plaster molds - I wish you could! Not sure about glass and plaster. When I did bronze casting we used ceramic shell molds - they could take the high temperature and pressure

[@tomgimon5267]

Metal casting is typically done using sand molds. en.m.wikipedia.org/wiki/Sand_casting Foundry sand is used because it can handle the high temperatures. Get in-person instruction from someone with experience before you try this because metal casting is a dangerous activity.

[@____Ann____]

And for glass the gypsum molds contain a high% of silica to make them tolerate the heath better

[@stephenhudson4931]

Isn't slip banned in America ?, its no longer available in the uk, because of health issues with talc

[@vantikistudio]

Why would it be banned? It is just clay. Same as folks throw pots with on the wheel - I know plenty of folks in the UK that use both clay and slip

[@Steril707]

Kind of eye opening how every single one of these different mugs is a months long project.

[@vantikistudio]

Yes! Showing folks that was one of the main reasons we started Tiki Technical Tuesday
