Product Information
Copper Oxide Powder - 100g

Mix this copper oxide with water or Glastac Glue and either paint or spray onto glass before firing.  

Apply between glass layers. Less is more, so this pot will go a long way. Great value!

Once fired it will create wonderfully random blue bubbles. Experiment to get the look you want.

Generally, the copper oxide gets darker with density and if applied very thinly will give a lighter turquoise.

Looking for a lighter, more vibrant blue bubble? Try the Glassline Bronze Patina Bubble Pen.

The elephant in the second image was painted using copper oxide on French Vanilla glass, by one of our students during a Personalised Day with us.

Used this product for the first time today and experimented with it, so impressed with the results and the ease of using the powder. Others have said it already, use thin sprinkles and you’ll get lovely blue bubbles.
Not sure if this powder was the reason but I added some copper foil elements as an inclusion too and they went a gorgeous metallic blue whereas it usually turns a rusty red. Gorgeous!

I struggled to get the right effect until I mixed one part copper oxide with 6 parts clear frit powder. I sprayed the base glass with hairspray, sifted the powder mix on and topped with top glass; perfect every time.

Received a sample of this with my last order, did a test tile, and all I can say is WOW fantastic results - just ordered a pot!

For a deeper blue (rather than turquoise) add a SMALL amount of cobalt oxide. Now that Warm Glass are delving into "hot clay" products, maybe they'll add cobalt oxide. Hint.

This product is one of my favourite with my students. we mix a small amount with water and sponge it onto the glass in a very fine layer before sandwiching. Brilliant for sea scenes and always a winner.

Fabulous value for money, with endless design possibilities- the trick is to mix it the same way as traditional glass paints; a little bit of water and ideally a bit of gum arabic powder to ensure it sticks to the glass. Thinner coating= smaller bubbles.

Blown away by this powder, played and played until I could control the effect and then started playing again ! Small amount goes so so far so it is worth every penny. Do buy this, you will not regret it !

Great product. I looked for some guidance on how much to use - but it is partly down to desired outcome. For anyone else looking for guidance, I used a small mesh sieve and sprinkled from a height the same sort of amount you would use when dusting a cake with icing sugar (remember to wear a mask). Produced lots of small bubbles with a good density.

I've just discovered this stuff, and it is amazing. I'm experimenting with it and getting some amazing effects! I'm delighted with my Skutt 14 kiln as well.

I like to use this with medium frit in moulds. Can be a pain to remove if you spill it anywhere and requires a bit of testing in order to get the effect you want (less is more, really).

Pretty blue bubbles for a fraction of the cost of bubble paints - the tub will last forever.

I mostly mix this with glastac and apply with a brush between glass layers. Try varying the amount applied, brush strokes and firing temperature for subtly different effects. Also try with dichro beneath. Do not apply too thickly or you get mucky looking smudge marks. Customers love the beautiful coloured bubbles. So do I.
