World Ice Art Championships

Just some examples of how ice can be used as an art form. Below are photos from the Alaskan Ice Art Championships. http://www.icealaska.com/

WIRED magazine article on making ice trays

In researching casting water and freezing it into solid forms, I came across an article posted by a contributor to Wired Magazine. Moldrite 25 by Artmolds and Ease Release 200 are the two materials this individual used to make his LEGO ice tray molds. He goes into detail on how easy it was. This process may be an option for testing the ice portion of my project.

Design Proposal--Project #3--Alternative Materials

The idea for this project is to pick a form and express that form through various materials. As an expectant mother, my mind is constantly on what it will be like to raise a child. From 'will they take to breastfeeding?' to 'will they get a date to the prom?' to 'will they live a long and happy life?' are thoughts I can't seem to shake but will really only discover through experience. This is what brought to my attention the many stages of life and how I might communicate them through material and form. I would like to carve a wax rendition of a baby pacifier (sketches and models to come), to cast out of multiple materials. This form is striking to me. Its clean, simple and strong, and an abstracted version of it will work well with my ideas. A pacifier is one of the first possessions one has. The nipple shape is symbolic of that of mother and her nurturing relationship with child. There are limits to what can be cast so I am choosing materials relative to my ideas I can only imagine will work. I may need advice and practice runs to test them.

Butter. Chubby newborn stage. Pure. Innocent. Simple.
Crayons. Playful infant stage. Creative. Colorful. Melted down able to be colored with once cast.
Metal. Teenage years. Cold. Hard. Distant. Frustration. Rebellion.
Rose Petals in Resin. Romantic years. Love. Heartbreak. Joy. Disappointment.
Ice. Old age. Weathered. Vunerability. Deterioration.
Since ice is a temporary material, I would like to include a hard substance to remain once the ice has melted. Something left behind, as we all do once we exist and exit our life cycle.
Pomegranate Seeds.

Assigned Reading-McCreight Ch. 4-Burnout and Melting


The purpose of the burnout is to evacuate the mold, cure the mold, and heat the mold to the proper temperature.
Allow 2-3 hours for mold to dry before burnout. The steam removal method is practical for soft waxes.

Burnout Equipment-kiln, long tongs, thick work gloves, high temp. nichrome wire, ventilation system, flask hook
To burn out in a kiln-remove when wax stops dripping out, then turn kiln up to vaporize any remaining residue.

Prep.-take off base, clear sprue area if not already visible.

Position-raise the flask slightly off the mesh with nail or coat hanger wire.

Burnout-set kiln to medium.

Fast Method-check every half hour until complete (when sooty black stain is gone)

Right Method-3 hour cycle 5 hour cycle
1@ 300 deg 2@ 700deg
1/2@ 700 deg 1 1/2@300 deg
1/2@1250deg 1@1000 deg
1/2@ 1250 deg

Do Not Overheat
wax vaporizes at 1250 degrees and at 1300 degrees the gypsum begins to break down.


Melting
It is important to avoid oxides from forming to prevent pits and staining-flux works well to protect the metal.
A larger torch must be used for larger amounts of metal-wear ultraviolet sheilding goggles.
Metal should be melted in small pieces.

Dave Grohl Podcast


Dave Grohl, from Foo Fighters, is interviewed and several songs from their new album is played on the air. I enjoy older Foo Fighters songs, as well as listened to Nirvana in my teen years, but was not crazy about the last Foo Fighters album. Liking some of the songs played on the 'Fresh Air' Podcast, from the new album, I also learned alot of new things about Dave Grohl himself. A multi-talented musician, artist, and poet he is and, as I highly believe in music as an inspirational tool, I think Dave had much to contribute to this art form and has changed many lives. I thought it was great how those miners were near-death and requested their music to get them through their frightening experience. Dave explains how he overcame much pain and many struggles to eventually make it big doing something he absolutely loved. Exposing his child to music at a young age is smart--he sings familiar words for her to sing along to, trying to divert her attention away from the television and into a more unique learning experience through song. In conclusion, Dave Grohl reminded me to keep using music as an inspiring resource and always aim high in your life's goals and dreams.

Assigned Reading-McCreight Ch. 3 Investment

Investment-'to cloth, cloak or surround (Latin root)
Can withstand high burnout temps.
Made of gypsum-a white mineral, calcium sulfate, responsible for the hardening of the plaster; silica-white and colorless mineral, quartz, to cushion while expansion and contraction (this is the main material that is harmful to breath in (wear a respirator) ; cristobalite-pure silica, enables to withstand the high temps. Some investments contain fiberglass for strengthening.

Store in resealable bag to avoid being exposed to moisture--use within 6 months or less.
If you suspect it has been exposed to moisture, measure it against some investment you know is fresh. (throw out if its more than 20% heavier than the new)

Never pour investment down the drain and use rubber mixing tools that the investment will easily crack off of to be thrown out.

Mixing
When mixing, you want to get a proper ratio between powder and water, mix it evenly, make sure there are no air bubbles, and do it within a specific amount of time.

Before mixing, make sure the model is clean, renove all dry investment from flask and mixing container, check to make sure the the fit is watertight, make sure the sprue is in tact, paint the model with debubblizer-denatured alcohol can work too but a debubblizer is not neccessary.

Investment has a working time of about 9 1/2 minutes. Hardening too slow will not give the investment time to properly settle around the mold. Hardening too fast will cause the investment to separate and bubble.

Use water of consistent temps.

Mix investment in a ratio of 38-40 parts of water to every 100 parts of powder by weight. Always add powder to water and not visa versa. Mix for about 4 minutes. Consistency should be a little thinner than sour cream.

A vacuum machine can be used to shake out air bubbles. Prepare this ahead of mixing. Tape a piece of paper to the top of the flask to catch any investment that might spill out while in the vacuum. Bubbles can also be vibrated out by a massager.

Assigned Reading-McCreight Ch. 2 Sprues

Sprues
A rod that supports the model while making the mold; provides passageway for wax to leave; entrance for molten metal; positions the model
Round soft wax wire is preferred for the sprue.
Plastic sprues are not recommended.
Attach to the thickest section of the model; where they cannot damage surface texture and can be easily removed.

Orientation
Leave 3/8" clearance on all sides of the flask; for several models leave 1/8" between them; leave 1/2" between model and investment.
Try to get your model situated to flow completely downstream to avoid air bubbles and backflow.

Recrystallization
As metal cools in contracts.
To avoid pits make sure to attach the sprue at the thickest portion and make sure there is enough molten metal supplied.
Choose a flask just the right size--too small can cause it to burst and too large is wasteful.

Attaching Sprues
Use a sprue wax slightly heavier than the average section of the piece.
Heat the wire and lower to attachment site--hold there until it hardens; check the joints and trim the wire if needed.

Fillets
Enlarge mass and round off opening at joint for smoother flow.
To thicken, heat needle with wax and drop off at joint.
Electric wax pens work well for this.

Determining amount of metal needed
Weighing-calculate ratio between gravity and weight of the model and the metal being used.
*Multiply weight x gravity of metal*
Use pennyweight or gram scale.
Weigh model with sprues.
If scale is not available, use the water displacement method (not as accurate)
Submerge wax in jar filled with water; mark how high the water rises with wax; take out wax; add metal until reaching the same point and maybe add a little more for the button.

Art of Innovation-Chapter 6

'Prototyping is problem solving...' That pretty much sums up the focus in Chapter 6 of 'The Art of Innovation'. It is encouraged that you jump right in and from one prototype make another that is even better. I like that idea. The 'build to learn' technique is something I am very fond of. Personally I can understand something and how it will work by molding with clay or a maquette. IDEO is expressing how many times it has worked for their team when they need to figure out how a mechanism will perform or be controlled. Take chances. The story about how the dot-com company started was inspiring. I did not know it all began by taking chances. I agree that models are tangeable and are more convincing than flat drawings. It makes since to throw the bad ideas on the table first. If ideas arent coming to you and all you have are ones you may not love, getting it out in the open allows room for others criticism which might help you make the next idea better. It is inspiring to hear how all the big companies 'got big'.

Art of Innovation-Chapter 4


Chapter 4 in 'The Art of Innovation' is on brainstorming. I have to admit I had not looked at this subject the same as I do now after reading the literature. I see how important it is to observe everyday people and events and how we interact with them. It is important to stay up to date with what is going on in the world around us. When it comes to brainstorming--don't take notes on every word but highlight important ideas. Contribute as a group and don't be afraid to voice your opinion even if you doubt it a little. Be playful and visual. A physical example is better than one just in words. Help the group visualize your ideas so they can add advice more efficiently. Warmups are not a bad idea as long as they are quick and highly energetic. Sketches and diagrams are also ok. Try to stay away from negativity. I personally wasn't sure what to expect from the brainstorming sessions we had last week, but once the group got going some really wonderful things occurred and much was accomplished. I am reviewing my own ideas in a different fashion and am not afraid to speak out or ask for assistance.

Blood Diamonds Imagery

Bullets
I thought I would look up bullets because of the relationship of the diamond craze serving as ammunition or 'fuel' for war. It turns out there are some really lovely shapes accompanying the bullet image. I was considering making a bullet referenced neckpiece with a noose going through it and also binding the hands, touching on the slavery issue--maybe with some interlocking wrist braces.


Kimberlite Pipe
I think the kimberlite pipe is an interesting scientific discovery--I just havent found a way to tie it into a project idea. The only thing I could come up with was veins erupting with diamonds....

























Maps
There are some nice patterns and shapes happening here.

Mining Carts

I like the antiquity to these old mining carts. The first one looks secretive because of the trunk-like shape to it. The various gears and wheels in the second one are nice, just not sure how I would work these into a piece yet.



Prosthetics/Amputation
I noticed toward the end the claw-like prosthetic hands that one of the blood diamond victims had been given so they could take voice in politics again and live a more normal life. I wouldnt want to use this image so representationally but thought about what something other than an arm or a hand might look like amputated.



Scar Tissue
In researching scars I decided to investigate a more dramatic type of scar--a keloid. Keloids are overgrown scar tissues that have regrown abnormally outside the boundary of the original wound. I like the imagery here in that they are 'deeper' scars so to speak. Something more unforgettable. I would like to use this as texture detail in my piece.

'Green' Materials

http://www.ecoact.org/Programs/Green_Building/green_Materials/index.htm

I will come back to this...

Second life


I started reading a little on this but am still unsure how I feel. There are probably other computer programs I would rather get into...I like Rhino so far. I know they are both very different but I can only dedicate so much time to a computer screen.


Ideas for historical study on jewelry











Id like to investigate filigree's past in relation to jewelry as well as incorporating it and new stone-setting skills into the studio piece.

I would also maybe like to research the history of a specific stone and design a project using that.
