The Platonic Solids are a set of five, three-dimensional, shapes that date back to the Greek mathematician Pythagoras and later named after the Greek Philosopher Plato, who paired each of the platonic solids with a classical element:

  • Tetrahedron – Fire
  • Cube – Earth
  • Octahedron – Air
  • Icosahedron – Water
  • Dodecahedron – Aether

He believed that these shapes were the building blocks to the creation of everything – in us, around us, and beyond

  1. Aegean College

    I was able to find good advice from your content.

  2. evisa bahrain,

    Fine way of describing, and fastidious paragraph to take facts about my presentation subject matter,

We can upgrade your shipping provider to DHL/FedEx/ DPD, but it costs extra. The delivery time even to the USA is 3 working days.

No, releasing lubricants needed, however, feel free to use one if you desire.

For our plastic molds, we use HDPE 300 and for our silicone molds, we use platinum cured, food-safe silicone.

When casting you should use the pre-glazing technique, in order to prevent any stones or metal shavings being in direct contact with the side of the mold, in order to do that when you pour the resin into the mold you do it by spreading a thin layer of resin on the inside part of the mold, just cover the sides with resin, it will form that thin layer that will prevent any shavings or stones showing up on the final castings. You should do that every time you are pouring resin into the mold. When you are closing the mold the first thing you need to do is to place tape along the open side of the mold, then to tighten the mold you can place one or a few more strings of tape across the edge horizontally until you close the gap complacently.

All silicone molds are FDA food safe approved, HDPE molds also can be used for casting food but they can not be heated when containing food

These molds can be used for resin, Candle making, Jewelry making, Molding & Casting, Sculpture, Soapmaking & bath.

Yes, but the lifespan of the molds won’t be so long. We use platinum cured silicone, not cheap tin cured one, the number of castings greatly depends on the chemistry of the resin used, the slower the curing the better as the heat released from the resin is less. There can be issues from the temperature that the resin build wile curing, we do recommend using layers when casting in the molds as you limit the heat this way.
