How to make a silicon mold of hydrangea calyx
Silicon molds shrink a little when they harden
So It is better to choose a larger calyx　
In this video I am making a mold for 4 sheets
I might have just needed one large calyx
You can also see some of my failures in this video(^^;)
【Case】
Make a case with plastic folder
Cut into strips
Round to fit the calyx
*The silicon overflowed, so the height should be about double this
Cut off the excess
Clip it on temporarily
Tape them together
Stick it on the inside too
Large enough that the calyx does not hit the wall
Clay for silicon
Match the size of the calyx
Push it in a little so it doesn't penetrate
It might be easier to handle if it were a little thicker
Seal the gap so that silicon does not leak
Check for any cracks
Inside too, just in case
These are completed!
Place in a vacuum pump container for later use
【Silicon liquid】
HTV2000 　Silicon liquid Soft type
Mix equal amounts of Liquid A and Liquid B
A little difficult to predict the amount needed
At the end, carefully drop by drop
Liquid A was 82 grams, so this amount of error is fine
Need to work quickly as it begins to harden
Mix well, even in the corners
Pour into the case
【Vacuum pump】
Vacuum pump to remove air bubbles
I made a mistake!
Be careful not to close this handle before turning off the power
Note that the current move is a bad example
Place the calyxes in the silicon solution
Push it in so as not to damage it
Vacuum once more
Wrong again,,
The correct way to do it is a little later, so please refer to that
Leave in vacuum for 10 minutes
Fast forward
10 minutes later
The calyx that moved has been repositioned to the center
Looks like no air bubbles!
Put in the freezer just to be sure
Roughly 10 minutes
I took it out of the freezer
Leave it at room temperature for 8 hours
8 hours later
It's hardening
【Once more】
There are thin areas, so add silicon
I think I'll just pour it up here
Make a new silicon liquid
Same procedure as previous work
This time it's perfect, so please use it as a reference
When the needle stops
Close the valve
turn off power
Leave in this condition for 10 minutes
Fast forward 10 minutes
It is correct to open slowly like this
Put in freezer for 10 minutes
10 minutes later
Leave at room temperature for 8 hours
【Separate】
Silicon overflowed and stuck to the bottom
Separate them with scissors
Cut a little at a time so as not to damage the calyx
I made the mistake of shooting in time-lapse
Slow version with different calyxes because it's tricky
Hook the blade to the end of the calyx like this
Separate the calyx so as not to damage it
【Try out】
I put potato starch on it to make it easier to see
Nicely done!
I made molds with lightweight resin clay
It looks good!
It is made with only the largest mold
Thank you for watching!
