Sometimes there are molds that just don't work. This is a great example of one I will avoid in the future. You can see here that I added in a lot of beads and EasyCast resin. I was hoping for a gorgeous casting but truth be told, I did not test this single mold shape in the tray before using it.
The bottom of the mold has a very thin wall area. Bubbles get caught here and you won't know until the resin is cured and you have demolded it. Bubbles in a thin area become actual holes.
So here is what I learned.
I was so disappointed with this casting because 3/4 of it is just gorgeous. Those darn holes were distracting me.
So, I thought I would just sand away the "holes."
Unfortunately, the more I sanded, the more bubbles I ran into. So, lesson learned. Test your molds. If I ever attempt to work in this one again I think I will do a simple first pour to just add resin to the edges and double check that it cures without bubbles before working in it.
Take a very very narrow ribbon or lace or even a pretty piece of cloth cut narrow and glue it around the base. Let that dry over night. Now just paint a tiny little bit of resin over it to add some shine and durability.
ReplyDeleteTada.... no more visible bubbles :-)
