FS999<\/span><\/h1>\n

My adventures and findings with different brands of Silver Clay – this blog talks about FS999<\/span><\/strong>.<\/p>\n

Recently, I gave myself a wee challenge. I was going to push past my comfortable relationship with the well-known brands of PMC and ACS and see what the other brands of silver clay were like. I have already blogged about FYI 999 and Prometheus 999 and you can have a look at those bloges by clicking on the links.<\/p>\n

This blog is all about my experiences with FS999. It\u2019s the sister product to EZ960 made and supplied by Cool Tools in the US. I did get it from the US along with some other lovely goodies from that excellent store \u2013 but I did get stung with quite a sizable import duty when it arrived, which is the price you pay when you import from the US unfortunately.<\/p>\n

Initial Impressions<\/span><\/h3>\n

I was excited to try this clay \u2013 I have heard lots of great things about EZ960 (and my experiences with this clay will be covered in a later blog), so had the impression that the FS999 would be just as good.<\/p>\n

When I opened the packet of the 50g bag, I found 2 bags of 25g. I love that! Aida do it with their bigger bags of ACS and I just find that somehow reassuring\u2026that the whole bag of clay isn\u2019t opened and that you don\u2019t have to go straight on and use it all in one or two sittings \u2013 NOT that I do that all the time! Have you checked out my blog about storing your clay<\/a>?<\/p>\n

I rolled it between my hands and it felt really nice. Soft and squishy, not sticky at all and I thought I was off to a good start. However, that\u2019s where the good experience ended.<\/p>\n

Working with FS999<\/span><\/h3>\n
\"\"<\/a>

Fraying at the edges – first roll<\/span><\/p><\/div>\n

When I rolled it out onto my mat, it started to \u2018fray\u2019 at the edges as you can see in the picture.\u00a0 I carried on and textured it \u2013 it took texture very well and cut out a heart shape with a template and a needle tool. I found this annoying, because when I was cutting with my super sharp tool \u2013 the edges frayed there too. This should NOT happen with a freshly opened clay. I expect this when the clay has been opened and rolled, rerolled and rolled again and even then, it didn\u2019t seem to be so noticeable. When I cut the hole with a cutter, it was a clean cut.<\/p>\n

\"\"<\/a>

Heart shape cut out with stencil and needle tool<\/span><\/p><\/div>\n

When I worked some more with the clay, I felt it was getting \u2018tired\u2019 very quickly and even when I added extra water to the surface, it still didn\u2019t seem to recover very well. It felt grainy somehow and after using it my fingers felt slightly chalky.<\/p>\n

I have to confess I didn\u2019t read the firing instructions (which I will discuss a bit later) expecting it to be like any other Fine Silver clay on the market out there \u2013 i.e. it has a range of different temperatures it can be fired at, so I made a setting for a glass cabochon. Just because that\u2019s what I was doing that day \ud83d\ude0a. Turns out in the suggestions for firing, it says the lowest temperature you can fire at is 788oC (1450oF) for 4 hours. No good for glass. But I only realised this *after* making my piece!<\/p>\n

I also made bails for my pieces, involved it being bent over a straw to dry. The FS999 did not like this one bit. It was cracking and unyielding, however, I persevered, adding more moisture as I rolled out again and managed to get a bail that wasn\u2019t too bad.<\/p>\n

When the pieces are dry, I found them to be quite flexible \u2013 not as flexible as PMC Flex, but bendy \u2013 see the short video clip<\/a>. I got a bit of a surprise since I wasn\u2019t expecting that so sanding and finishing \u2013 especially on some of my more complicated pieces was challenging.<\/p>\n

Firing FS999<\/span><\/h3>\n

Firing was straight forward. There is a firing schedule given with each bag of clay<\/p>\n

It is:<\/p>\n

1650oF \/ 900oC \u2013 30 mins \u2013 2 hrs (depending on the size of your piece)<\/p>\n

1600oF \/ 871oC \u2013 I hour<\/p>\n

1550oF \/ 843oC \u2013 2 hours<\/p>\n

1450oF \/ 788oC \u2013 4 hours<\/p>\n

Now since the difference in temperature is so little between each of the breaks and the firing time goes up quite a lot, I wasn\u2019t sure why or to what benefit each of these different firings meant.<\/p>\n

\"\"<\/a>

Firing examples Top – Kiln fired (900oC for 2 hrs) Middle Kiln fired 700oC for 30 mins Bottom Handfired for 5 mins<\/span><\/p><\/div>\n

So I just kept things simple.<\/p>\n

I fired 3 test pieces. One at 900oC (1650oF) for 2 hours like I do with most of my silver clay. Once at 700oC for 30 minutes \u2013 this was the glass firing schedule and I wanted to see if I could fire this clay at that temperature and I handfired one.<\/p>\n

The pieces fired at 900oC fired well and were strong \u2013 so no issues there.<\/p>\n

The glass pieces I fired at 700oC for 30 minutes *looked* OK \u2013 but the test piece, my heart, broke when I tried to bend it. Quite clearly, the piece hadn\u2019t sintered. I\u2019m guessing this means that the glass pieces also didn\u2019t sinter although it\u2019s harder to break them. I guess this is unsurprising since nowhere on the instructions did it suggest firing at this temperature for this time!<\/p>\n

My handfired piece was fired for 5 minutes as per the instructions and fared well. It felt reasonably strong (as strong as I would expect a handfired piece to be) and didn\u2019t snap like the piece fired at 700oC for 30 minutes.<\/p>\n

You can see the differences in shrinkage between the top kiln fired piece and the bottom handfired piece. The piece in the middle was fired at 700oC for 30 minutes – hence the break.<\/p>\n

And for those of you who were wondering about how the pieces fared with the glass… well they survived, but I wouldn’t trust them since the test piece that I fired at the same temperature broke. My lesson? Read the firing instructions BEFORE designing a piece!<\/p>\n

All pieces polished up really well afterwards, so there was no indication of how tricky this clay was to work with!<\/p>\n

Storing FS999 and its longevity<\/span><\/h3>\n

\"\"<\/a>

Challenging cut out – FS999 after being stored for a couple of days<\/span><\/p><\/div>
\n

\"\"<\/a>

You can see the raying quite clearly in this picture<\/span><\/p><\/div><\/p>\n

I didn\u2019t use all the clay at once and popped the rest in an airtight container with a baby wipe for company (this is my way of keeping moisture in the pot). But when I came back to use it \u2013 I made a toggle clasp from a lovely but unfortunately discontinued Dynasty texture sheet which involved a lot of challenging cutting out, the clay became quickly unusable.<\/p>\n

And I mean unusable. It didn\u2019t survive being kept in the pot I described for a couple of days. It actually started to crumble on me!! Crumble! Like when you\u2019ve overworked pastry and it won\u2019t stick together any longer. I was really annoyed with it and put it in my waste pot for reconstituting at a later date. I would say it was roughly 15g of clay!<\/p>\n

Conclusion<\/span><\/h3>\n

I am sure you know what I am going to say now\u2026\u2026I wouldn\u2019t recommend this clay to my students. Especially beginners. It\u2019s too challenging to work with and it gives a bad impression of what silver clay can do. I have since seen reviews and questions about it in one of the metal clay Facebook groups I am a member of and it seems I am not the only one to experience these issues. However, unlike them, because I was based in the UK, I couldn\u2019t easily return the product.<\/p>\n

There are better fine silver clays out there. Try them first.<\/p>\n

Until next time, happy claying!
