Decals And Torch Enamelling


I love adding designs to things so when I discovered you could combine enamel decals with torch enamelling I had to have a go. I ordered the decals a while ago and after a quick go which left me decidedly underwhelmed with the result I kind of lost interest in it and left the decals in a drawer for a while. I thought I'd better have another go last weekend so dug them out again.
I don't have my first attempt but I did discover that colours don't work too well. The bright designs I uploaded to be transformed into decals came back decidedly dull looking which looked equally dull after being fired onto the enamel.

Here's part of one sheet of decals ......


The photo is a bit deceptive as the decal sheets have a blue tint to them in real life due to the layer of varnish on top of the enamel decal which burns away during firing which isn't showing up in this photo. The colours are also a lot duller! {Damn you camera for making something look white just when I don't want you to!}
I thought I'd try using one of the black three ball flower decals this time and you can see the results in the top photo.

I was pleased with how they looked but bear in mind this was just a quick experiment. The colour of the decal changes to a sepia tone which is quite nice. I fired a layer of clear transparent on top of the round discs as the decals can sink a bit during firing.
The bullet shaped earrings had a harder time of it! I tried a coloured decal on them first and followed some advice I found online about applying the decal, letting it dry then sifting a layer of clear enamel on top before firing. The result was the varnish covering the decal ignited briefly and the already dull colours in the decal faded badly. I wasn't going to give up though so then added another layer of mint opaque enamel on top to cover it up and had another go with the black ball flower design this time.


This worked ok and also produced the interesting effect you can see around the edges where the clear enamel is pushing up through the mint opaque layer above it. I really like the effect and will be experimenting with it again soon  
I'm going to leave these two pairs of earrings for a while to see if any cracking or other weirdness happens before I do anything with them.

Here's another experiment with one of the coloured decals. This is the original design....nice and colourful....


and this is the result after firing the decal.....


The colours are very dull. I'm sure you've noticed that the enamel is badly cracked too. I didn't bother to counter enamel the back as it was a quick experiment. So after two layers of enamel and three firings the difference in expansion and contraction rates of the enamel and copper caused the enamel to crack the day after firing. I used 24g {0.5mm} copper sheet.
So for all those who torch enamel and think you can get away without enamelling the back on thinner gauges of metal, this is what can and probably will happen if you don't!


I have some more decals on order {no colours this time!} so as soon as they arrive I'll be experimenting again and will take photos of the process so I can post another one of these slightly rambling posts with much better results hopefully!

  1. Gorgeous colour on those earrings.
    Isn't it always the way, when you want a crisp white background, it never happens!

  2. I find these experiments very interesting - do the colors just become dull or light? Can it be used in pieces where we want the design to fade into the background at the edges creating depth of field

  3. Can I ask where you purchased your decals? I haven't had much luck finding any cute/interesting ones on the internet yet. I like the ones you did - but am also looking for short quotes that I might be able to add to bracelets, etc. Thanks. Casy

    1. Hi Casy,
      I got the decals from - http://www.fotoceramic.com.
      You can create your own designs or text {or use free to use clipart, etc} then upload them to the site.

  4. The decals are so cute Tracy! I know you will master them in your work!

Etching Silver Using Nail Art Stamps

So my love/hate relationship with etching sterling silver continues. I've tried a few times now and always end up with different results most of them not that great to be honest. I've tried connecting the silver and a piece of copper to a 9v battery and also heating the ferric nitrate. Sometimes the results are good sometimes not so good. I currently have an etched piece of silver sheet waiting to be reticulated and rid it of the mess that is the etched "pattern". 
I now know that using stamps and Stayz On ink just doesn't work with silver - the time needed to etch using ferric nitrate is much longer than etching copper and the ink starts to wear away after about an hour. This results in the pattern being patchy as the resist is eaten away and the silver ends up quite lumpy and course looking. I have yet to try using pnp paper. I don't know why but it all seems a bit of a faff to do. I don't have a laser printer so would need to find somewhere or someone…

Embossing Metal With My Sizzix Bigshot

I must admit up until a few weeks ago I was vaguely familiar with the name Sizzix but as to what you actually did with a "Sizzix" I was completely in the dark! That was until I stumbled across a video from Vintaj showing how you could use their embossing folders with a Bigshot to create designs on metal ("metal" - my favourite word after chocolate!)
I was really impressed and itching to have a go, I just needed a Bigshot........ I waited a few weeks then when the urge to possess one overcame me I went out debit card at the ready..............and the shop had sold out! So I trundled off to The Range on the off chance and came home clutching my own surprisingly heavy pink and black wonder machine. It sat on the dining room table for a couple of days while I waited for the embossing folders I'd ordered online to arrive then the time came to start playing!


I started with some pre-cut 24g copper hearts and the Wildflower Vines and the Butterfly Swirls Deco Embossin…

Rolling Mill Textures On Metal

I had another play with my rolling mill last week using some of the texture sheets from Etsy shop Rolling Mill Resource. I used some sterling silver and copper sheet and soon discovered it's best to get organized before you start!

I cut the sheet to size and worked out which design was going on which piece of metal. I also tried a feather but more on that later. Most of the sheet I used was 20g/0.8mm with one piece of 18g/1.0mm and one of 22g/0.6mm.
I've read that you should do a dead pass of the metal through the rolling mill with the gap the same size as the metal and texturing item. I'm not sure what this is supposed to achieve but I don't bother doing it. Judging the correct size of gap between the rollers is a trial and error thing that you discover by setting the gap then starting to roll the metal through. If there's too much resistance you make the gap bigger until there's just enough resistance to roll the metal through without giving yourself a herni…
