Sculpture update (Rhino/Orangutan/Tiger)

RHINO update

last layer for the rhino moulding

finished, remind myself the screw could not be inside, now the wood board could not separate…is not good for next step…e.g. drying and opening of mould.

open it!

the dividing not very successful, hope it do not affect the casting so much

the lower piece, bottom left corner not firm and hard enough due to not mixing well of plaster….to be careful of washing

———————————————————————————————————————————————————

ORANGUTAN update

starting from wooden frame and wire to form the basic structure.

putting the clay on

after 2-3 nights…keep editing the….this model is difficult in balancing, and I want to make a good form with my style as well….so finally finished

     

now go for moulding, something to hold his back so that it maintain “floating” on the plaster

as the form is complicated…leaking always happen

this is what I said “floating”

the mixing of plaster should be in quick and accurate amount…CONCENTRATE 

finally I divided the mould into 7 pieces, and the rhino one just 3

all wooden board removed for opening

————————————————————————————————————————————————————————

TIGER update

same…begin with wood and wire

clay on…this one ….difficult on standing

rough shape

the back…top view…I love the shape very much….a bit similar to my toy (battlecat from he-man)

almost finish, the gain or pattern will be sculpt after casting…..since those pattern will further make the sculpture weak…crack….and adding difficulty to the moulding …….and….one of the reason is every tiger’s pattern are individual….like fingerprints of human…so sculpt it out would be fun!

keeping it wet by plastic and wet towel

bring to uni and start moulding

the eyes take me so long for crafting, editting and crafting back and for….

the hand’s are cracked and brokennnnnnn! this one is too challenging, coz I do not have a stand for it….how to make it floats on plaster?!

finally start….remember to spray oil, on both the clay surface and plaster dividing, is really useful!!!

to be continued~

Rhino moulding update

After the tiger mould (7-8 pieces) , this time with a simpler form, clearer outline rhino, still a challenging task but seems under my control…feeling happy to keep working on sculpture.

screw it on the board so that it could be in the middle of the mould.

still, the sculpture is heavy….at the moment I prepare plaster and clay blocking any edges, I need to add some support to that.

1st piece is half of the mould, it consumed me a lot plaster, the whole bucket (around 25cm diameter, 40cm height)

as the ears are one of the difficult separating part for the mould, I try to make it better…try, probably it need to craft after casting

horn

clean and use soap the polish the surface

another pour for separating negative space between ears, and also that of belly and leg

  

the forth part:

Starting the rhino sculpture

I am now starting to make the rhino sculpture, this time I will make the shape clean and the lines easier for the mould. Because a better mould could cast more and better result

start to use wire and cling film to hold it tight, and putting clay on top.

Tiger Casting Update

Cool down and the lip balm would shrink, so all the clip I use should release before if cracked.

before opening, I try to take photo to remind myself where is leaking a lot

opening

still a lot to fine tune and even craft again, but is a very good experience and result for me to do so many pieces mould.

comparing the clay model and the casted piece

the fur on chin gone a lot, the ears which are curved into the mould, are damaged. so next sculpture should consider the simplicity or dividing mould carefully.

Tiger Casting

So, how to calculate the amount of mixture I needed?! is not difficult, just gather the volume, weight, and plaster density~

and after I got those information, I feel secure to cast it…(well, I already ordered enough materials actually…..just always need to have a clear picture before I do)

and…one more thing is to add two coloumn into the mold so that the final piece could be hang on the wall~

okok….enough…..let’s cook! I have prepared 2 sets of secondary boiler

as they solidify quickly, I have to boil them at the same time (I don’t want to left the color difference for the casting)

the working environment,

as they all melts, I keep mixing the two bowl, to ensure the ingredients are same proportion.

pouring the mixture into the mould, they keep leaking, next time should have clay or something else to block it.

solidifying~

a bit crack due to it strink

finally, because of leaking so much….the neck of tiger is missng, I will boil the mixture and add into the casting.

Update process of tiger mould

continue from here:

5th piece:

the 6th piece, is too large and not level with 4th and 5th, which is not good for separating are on,

the final piece on top is a bit large and flatten

final one, with drawing on top, identifying the direction,

also draw the lines of the different pieces

and take out the board in the bottom, let it dry.

beginning to separate it, try to take the clay out, but that’s too tight

after a long time using a saw to cut the edge, first part come off~

keep cutting, hard work due to the lack of polishing each pieces surface!!!

finally done with some unexpected separate part, using rubber band to hold it, hope it’s fine

putting in the dry out cabinet:

wash with brush:

some improvement for next time:

1) use cooking spray on the surface of the model, or hair spray, just a layer

2) use thin and smooth sheet inserted into the mould, as seen on youtube, to make a better mould.

now….too much cracking (plaster not mixing well) and in the process of cutting off the mould…..so that the final piece casted out would need a lots of work to fine tune or sculpt.

Tiger Mold Making

After my Canada trip, limit time access to the college XP, waking up late…….:( the clay tiger model dry out and crack on several point….have to hurry up making the plaster mold,

1) using wooden board, acrylic sheet to seperate certain area:

forgot to take photo after first pour~ but the plaster not dry out yet after 1 day….I am thinking if that is because of the water inside the clay…..and that’s why I can’t use the soap to wash the surface well……anyway I am in a hurry for the second part:

according to the youtube I watched….I should bring some oil in order to separate it well…..now i try to use a bit soap.

and I am doing the 3rd pouring on the day I am writing this……

oops…..disaster…..I should use a smaller container to pour in, now the plaster cover some other area which may lose some details….:( and….using those small irregular shape of acrylic would easily make it leaks….or, I should take reference from youtube….use copper sheet to divide those pieces….and pouring all the area at the same time?!
