Do I need a Kiln for Silver Clay?

Silver clay is a versatile material that allows jewellers to create designs outside the scope of traditional metal-smithing. It can be moulded and shaped into unique designs and is both a versatile addition to the seasoned jewellers toolbox and an excellent material for beginner jewellery-makers alike.
There are many different types of Silver Clay to choose from; it comes in different forms and in different alloys and the different brands have different firing requirements for each of their clays, so when you’re getting started it can be tricky to know which ones to choose and how to use them.
And on top of that there are the tools. Which ones do you really need? And the most frequently asked question I get asked is:
“Do I need a kiln?”
And the answer is No. (But sometimes also yes)
When can I torch fire?
In most cases, Fine Silver Clay does not require the use of a kiln for the firing process. Instead, you can effectively achieve the right firing temperatures through the method of torch firing, which makes the overall process significantly more accessible and convenient, especially for those who are just starting out on their jewellery-making journey.
When can’t I torch fire?
As a general rule, Sterling Silver (925) and Britannia Silver Clays (950) require firing in a kiln. There are many different brands of Silver Clay to choose from though, so remember to check the manufacturers guidance before purchasing.

How to torch fire
Torch firing takes patience and a little getting used to. Once your clay is completely dry heat it up evenly with a torch. As you heat the silver clay piece, you will notice a colour change from dull grey to an orange glow. Maintain the orange glow for 3-5 minutes depending on the size and thickness of your piece, moving your flame constantly to avoid hot spots or melting. Once fired, leave to cool.
Tip: The biggest pitfall with torch firing silver clay is under-firing. An under-fired piece of silver clay may become brittle and break. It’s really important to be thorough with this process, especially when creating fine or detailed work.
