You asked, so we delivered. 

Our squangular pipe molds are finally here. Molds are an excellent tool for ceramic pipe making, but they are not for everyone. Not sure if a mold is suitable for you? No worries, you can always purchase the bisque version here. We also offer an option to glaze the inside so you can focus on the fun part, decorating your pipe.

Please Note: This mold is ONLY for pouring pottery slip pipes. You can not use this mold to pour concrete, resin, epoxy, or anything else. Doing so will ruin the mold and wouldn't be safe to use.

 Product + care

- 1 Plaster squangular pipe mold

- 2 rubber bands

As long as you care for your mold correctly, you should get over 200 casts from one mold. Never scrape the inside of your mold, as it will leave permanent scratches and will reflect on the finished piece.

If you need to clean your mold, use a wet sponge to wipe the inside, do not dunk or put it under running water.


Remember that using molds takes practice and can take some time to find your flow. We always like to think of the first pour as a practice test. The first pour also removes any remaining plaster bits, dust, or other impurities, making the rest of your casts clean. 

Not all slips perform the same. When making pipes, you will want a more runny slip for easier draining.

Every mold is hand poured and may have some slight differences. Since each mold started as a handmade prototype, there may be some slight texture in the mold. Use a wet sponge on your finished piece; it will smooth out any imperfections.
