SET OF FOURTEEN DOME SILICONE INSERTS Sent from Pacific Paradise Qld 4564 Australia This very unique set of silicone inserts consists of four different sized domes. Extra large x 2 - 40mm (2.6") wide Large x 3 - 30mm (1.2") wide Medium x 4 - 26mm (1")wide Small x 5 - 22mm (0.8") wide These amazing dome inserts are made from high quality white silicone. They are about 8mm ,(0.32") thick so you will need a deeper mold to use them in. Place the dome inserts directly into your silicone coaster or tray mold. These domes would make an amazing clock. Purchase two sets of domes and use the bigger domes for 12, 3, 6 and 9 o'clock and the smaller domes for the other numbers. You can see me using these inserts to make a tray on my YouTube channel. The potential to create beautiful pieces with these dome inserts are endless. NOTE: My silicone is heat resistant up to 120 degrees celscius (248 degrees fahrenheight). If you overheat the mold using your torch, you WILL melt the silicone and it will stick to the resin. This is not a fault with my mold, it is user error so please be careful using your heat gun or torch.
