IOD Moulds & Stamps
IOD Moulds can be used with many different mediums. We will cover the two most common here. Every medium has its own characteristics, challenges, and virtues.
Air dry clay, or paper clay: IOD paper clay is an air dry medium, and one of our favorites. Like most paper pulp based air dry clays, some shrinking, warping, and cracking is inherent. We like these qualities for a distressed, authentically vintage look. Our favorite way to apply moulded pieces is to remove them from the mould while still moist, and adhere to the surface with the appropriate glue so it conforms well. For vertical surfaces, use a piece of low tack tape to hold it in place so it doesn’t slide.
Casting resins: There are some great pourable resins available. These have completely different qualities than the paper clay. There is no shrinking or warping, and the castings are more consistent. Depending on the project, these qualities can be helpful. If you need to conform them to a curved surface, this can be done if removed from the mould before it’s completely hardened.
On releases: We find that most of the time a release is not necessary and the casting will come out without the use of a release, however, if you are having trouble with the material sticking (more common with clays than resins), a light dusting of simple cornstarch or arrowroot is a great choice.
IOD stamps are a clear stamp which have the magical power to transform furniture, home décor, food art and even clothing.
HOW TO PREP IOD STAMPS
New IOD stamps need to be conditioned before using. You only need to do this once and then your stamps will be set for life. Start by removing the acrylic sheet attached to the stamping side of the design, while leaving the stamps attached to their backing sheet. Using a fine grit sand block scuff or rough up the stamping surface. Lightly sand in one direction and then rotate the craft stamp 90 degrees and sand lightly in a different direction. This helps the mediums stay put, and not bead (which some types, like ceramics glazes, tend to do). It also will give a cleaner impression.
TO REMOVE THE BACKING OR NOT TO REMOVE THE BACKING
Some of our stamps work best if you pull the stamp off the backing and use a thin mount when stamping. Others work best if you leave the backing on and then there are some that we keep the backing on, but cut each stamp out separately. Let’s break down what you should do with which types of stamps.
Any letter or alpha stamp set such as Typesetting, Farmhand, Retro and Swoosh: Remove the stamp from the backing when ready to use (this takes some force, but don’t worry, the stamps are strong). Arrange the stamps design side down on your project, then lay an acrylic thin mount on top. Press to adhere the stamps to the thin mount and then apply your medium. When you’re done using your letter stamps, clean them and stick them to the backing for storage.
Any stamp that comes as a sheet such as Carrara Marble, Craquelure, Distressed, Chippy Paint, Kindest Regards and Cubano: Leave the stamp in one piece on the backing and the backing will work as your mounting surface.
INDIVIDUAL STAMPS WITH MULTIPLE DESIGNS
The majority of our stamps fall into this category. Examples are Painterly Rose, Pavo, Fronds, and Crockery: Leave the stamps on the backing. Cut each design out separately making sure to round the edges of the backing when you cut. The backing will work as your mounting surface.
