Crafted Elements has always been known for its functional art molds and being "the first" to create specialty molds never seen before. With the rise in popularity of house plants and plant propagation plus a little inspiration by one of our customers, Jenni Chapman (@createdbyjenni) we have released the worlds first big plant propagation stand mold.
In its simplest form this mold allows you to create an 16x3x3" block with five 1" diameter, 2.125" deep holes down the center. These holes are designed to fit the common short or long 25mm (1") diameter test tubes or plant propagation tubes that are commonly found on the market.
The size and volume of this mold allow you to encase objects within it, to create truly one of a kind propagation stands with room for up to five tubes.
Important Note: Despite the 3/4" thick sidewalls on this 16" long x 3" tall mold, physics is not on our side. If you pour resin into this mold all at once (instead of in multiple 1/2"-1" deep pours) you will see some bowing along the length of the mold. To ensure you cast a straight piece be sure to put a flat edge, such as a box, a piece of plywood, etc. along each of the long sides of the mold to ensure the sides stay straight.
Crafted Elements Silicone Molds
The last mold you will ever need. Created just for makers, resin artists and wood workers, these time saving flexible yet durable silicone molds significantly cut down on the setup and demolding time usually involved with other molds. Silicone molds are superior to wood and tuck tape, and HDPE molds because:
They can be used with epoxy resin, resin and wood, concrete, Jesmonite, plaster and more.
They never need assembled, or disassembled. Saving huge amounts of time.
The strength and flexibility of the molds allows you to insert and remove pieces of wood easily.
The corners and edges never need sealed.
When using wood, the wood stays in place, tight in the mold if you cut it 1/16" larger than the width of the mold. Preventing the need for clamps or weights.
The mold is heat resistant to ~450F. Avoid direct contact with the flame of a torch. Briskly wave your torch or use a heat gun to pop bubbles.
The molds are reusable. However silicone molds do have a finite lifespan when used with epoxy resin, but getting 20-30+ castings out of the mold can be expected when they are properly cared for and a non-silicone based mold release spray is used.
Like HDPE, epoxy resin does not stick to silicone. However, the heat generated by the exothermic reaction and the chemicals in epoxy resin are very harsh to all silicone molds. Additionally, if part of your epoxy has not fully set due to improper mixing, the epoxy can become bonded to the mold. Both of these factors can lead to mold tear out when removing your piece from the mold, leading to pits and tears on the surface of the mold. This is why we a non-silicone based mold release spray is required before each pour. To help prevent tear out and to increase the life of your mold. We use the 'MG Chemicals 8329 Non-Silicone Epoxy Mold Release', 'Smooth-On Ease Release 200', 'Mann Ease Release 200' or 'Mann Ease Release 300' which are readily available from Amazon and other online retailers. Cooking spray, vaseline, silicone based sprays or sprays designed for urethane or polyester products should NEVER be used. Using a proper, non-silicone based mold release can mean the difference between getting only a couple of uses from your mold to 20, 30 or more.
