Stunning piece of glass, my dad loves his 25cm x 20cm large coaster as it can fit 2/3 glasses on it!

Tania Le Marinel

Really disappointed. I ordered a sheet of this glass and at least a third of it is plain red so it's totally not as shown in the picture. I understand the design is unique to each sheet but I can't use it for the project I intended as I needed a full sheet of patterned glass (as shown on the website) not a large plain red area. It's not the first patterned glass I've ordered which hasn't looked the same as the website example so be prepared to get sheets that aren't what you want/need.

WARM GLASS RESPONSE: Hi Tania, we are sorry that you were disappointed with your 25x20cm sheet. This size represents approximately 1/8th of a full sheet so, as stated in the description, will not include the full pattern. We want all our customers to be happy with their glass, so our Customer Services Team have contacted you to offer you a refund on this item.

Useful to note that this glass is quite stiff and may require a higher fusing temperature/more time. I only realized this when making a coral bowl. Otherwise I have used this glass in multicolored bowls at the normal recommended temperatures and times.

A beautiful, deep red. If you need red in your work you really can't go wrong with this shade!

Kate Webb

Gorgeous vivid red. Its a beautiful shade and transmits light to make it even more striking. I use this a lot.
