Making a heat resistant silicone stamp for a bonbon mold like

[Julie de Lara]

Does anyone know what kind of silicone Andres Dubovik is using to make his silicone stamp for his bonbon mold?  Whatever it is, it is clear and heat resistant. He tapes a mold with a design he wants, sprays the mold with cocoa butter and pulls up the tape leaving the design in the negative space. Then, he fills the cavity with silicone and puts a popsicle stick in the middle. When it hardens he pulls out the stamp. Then, he sprays his mold with cocoa butter, jests the stamp with a heat gun, presses the stamp into the cavity for a second and comes back with a sponge to blot up the melted cocoa butter, letting the stamp create the those negative spaces. Then he goes back and sprays his second color, representing the design. The silicone he uses is translucent and heat resistant as he heats it with a heat gun after it solidifies. 
 

Here is the link to the video on his Instagram account. Hopefully you can see it.

Also, does anyone with a Fuji spray gun know roughly how many grams of cocoa butter the use to spray a mold with about 30 11gram cavities?

Welcome @Julie de Lara.  Not sure what it is but Chef Rubber now sells smaller quantities of silicone silicone offerings.  I would suspect it's the highest durometer reading version you would try.

This may be the product.

Do you think it is a technique or tool worth trying? I believe there has to exist some stamping/stenciling technique that can be actually applied to 50+ molds while being effective. Unfortunately, I didn't find it yet 😅
