If you have been lucky enough to attend an UnEarthed beginners class or have prior experience in sand casting and would like to develop your skills, add new techniques to your repertoire or have a great day making more jewellery for your collection. This Intermediate level class is for you.

In this one day workshop, Kirra-lea will guide you through the process of designing and sand-casting jewellery pieces or small objects with the twice cast technique. Learn how to sand cast mixed copper, brass and silver pieces. Add gold if you wish. Bring old gold to melt down or bring gold scrap or granules. Everyone is provided with 30g of sterling silver with the option to purchase more.
During the day, you will have time to make at least three jewellery pieces. Three projects will run through different ways to introduce mixed metal to your design. You can then either spend some time cleaning and polishing your pieces ready to wear, or you can continue playing and cast more pieces to be finished later in your own time.

What To Expect

What You Learn

  • Sand casting, by its very nature, can lead to a myriad of unexpected outcomes. You can expect to learn about the equipment, tools, materials and techniques required to create unique sand-cast pieces.
  • Kirra-lea will share tips and tricks that she has learned over many years of sand casting in her own studio, along with her passion for this technique.
  • Learn how to use the twice cast technique in three variations.
  • You will be given three projects. Each project will be your own design concept exploring and applying the demonstrated twice cast techniques.
  • Please note that so students have the maximum time available to learn this new technique and make multiple pieces, time will not be built into the day for cleaning up the cast pieces. Students that do not have access to a studio can book time in the classroom on some Wednesdays to attend our Jewellery Bench Access to finish polishing their pieces.

What You Will Make

  • one pendant with mixed brass and silver.
  • one pendant with mixed copper and silver
  • one ring with mixed copper and silver
  • additional piece/s of the students choice if time permits

What to Bring

  • Sand casting can be used to replicate almost any hard object and turn it into precious jewellery.

Note that the larger the object the more silver will be required adding to the expense of the silver.

Fantastic class and you walked away with completely finished pieces! Kirra-lee was a wonderful teacher, very engaging & knowledgeable. Square peg studios were well equipped and the small class size was perfect. Would highly recommend the sandcasting course.
