What is the average lifespan of these bioplastic stamps?

The behaviour of the materials we use (bioplastic) and its degradation is similar to ordinary plastics. PLA is a little bit harder and therefore more durable (similarly as hardwood, for example oak).
The "bio" of the plastic means that it is biodegradable, however it only degrades in compost, not during your workshop :)
Our tools are intended for hobby use. (They are not made of stainless steel.)
If you use them according to the instruction manual, they will last for many years.

Will the stamps stick to the clay?

These tools are very similar to wooden tools in the way they react to clay. For best results use them on almost leather hard clay. If you need to stamp into wetter clay we recommend that the stamps be slightly oiled, a few drops of vegetable oil on a sponge is enough. Or you can lightly dust them with cornstarch before stamping. Alternatively, stamp over plastic wrap or a cloth, you can get some interesting edge effects this way.

How do I clean the stamps?

When cleaning the stamps we recommend washing them briefly in warm water (max 50°C) and then rinsing them under running water using a sponge or non-metallic brush to clear away any clay residue. Shake off any excess water and dry on a towel.

DO NOT WASH THE STAMPS IN A DISHWASHER!

Are these easy to use and store?

For easy usage and handy storage in the studio, use the wooden rod (1 included in each pack). Buy extra rods (8 mm diameter) in our e-shop, singles, or packs of 10 for better value. Store them upside down in a mug so they are always on hand.

Where can I buy extra rods?

Extra rods are available in our e-shop either as singles or packs of 10 for extra value. Alternatively, you can purchase any softwood 8 mm rods and use those. If you have any difficulty inserting your rod try 'screwing' it into the stamp holder or roll 1cm of the rod on a table edge to slightly compress it. This should make it fit more easily.

Are Relyef tools only for use on clay?

Our tools are suitable for use with clay, polymer clay, modurite, and many other similar products. Fine patterns work best on fine clay and larger patterns for coarser clay. When using an oil-based clay, eg. Plastelin, consider stamping using a plastic film to make the cleaning of the stamps easier.

Our stamps can also be used, to a limited extent, on wet leather.

To avoid damaging the stamps, use only manual pressure, avoid using a press or vice. At present we are working on an alternative product that has increased mechanical resistance. If you're interested in this technique, please do not hesitate to contact us.

Is it possible to use Relyef stamps for soap decoration?

We can't say this from our own experience, but we do have a few satisfied soap maker customers, who gave us these tips for you:

 

1st tip by Saskia from Sunshine Soaps - New Zealand: "I purchased the chakra pottery stamps to make my chakra soaps for a course I'm running. I could purchase moulds for soaps but I really wanted stamps. So I risked buying these with fingers and toes crossed. I'm so delighted that they worked perfectly. Great people, great service, I highly recommend. Next, I would like to try the earth, wind, water, and fire ones. Happy soaping everyone BTW my soaps are CP and stamped the following day after unmoulding."

 

2nd tip by Misty from Carolina Organics Soap Co.: "These stamps work amazingly for me. The best advice is to wait till your soap has been cut into bars and then cured for just a couple days. By then the soap bar is firm enough to handle the stamping pressure but soft enough so that it only takes a little pressure to make the image. The stamps can also be dipped into shimmer for a more bold effect! The time to stamp may depend on the soap recipe but most of the time two days is the perfect amount of time to stamp. My recipe cures very hard so I could wait any longer than that. Some soaps that remain soft longer could be stamped later on in the cure process."

 

         

Is it possible to use Relyef tools on leather?

Reliéf tools are usable (to a limited extent) even for pressing into wet leather. To avoid damaging the dies, press them manually, gently, without using a press, vise, or similar mechanical tools.

For pressing into leather we are working on making special, low-handed presses with increased mechanical resistance. If you are interested in this technique, do not hesitate to contact us.
