Yes, I built a wall light panel with these. I used the plastic strips available to allow me to seat the blocks on silicone, the strips also are used between the blocks as spacers. I can't remember the source after 13 years, but search on line. The strips are about 3ft x 2 in x
1/4 in The blocks sit nicely on the strips, but only use silicone in the middle to fix the blocks, use acryllic filler to finish off the joints on the outside. I didn't do this and it was a pig to get the blocks clean with a golden fleece and a lot of work. Using silicone + acryllic means any movement is absorbed, so no cracking of blocks or joints. The plasic strips give the wall rigidity, so no reinforcing is necessary. If I can do, I'm sure you can!
Just looked up the records, the brand was Speedset, but I have no record of whom I bought the plastic strips from. Can't trace someone selling this product at the moment, but newer products of the same type are around.
Old money would eat it if the label called it a conserve, New money if is labeled a preserve, Those who feel they should have money but don't due to wanting to live in a hip area and paying of their student loans eat jam providing the label has Artisan made on it.
They're easy - it's just a big tiling job. The vendors sell the bits you need - blocks, mortar, metal rods to hold it all together, expansion strips for the edges, and instructions on what to do.
(though I'll admit I've never done one myself - but a builder here did one for us with no prior experience and it came out fine).
Google found me a supplier when I wanted to buy the stuff. I used simplyglassblocks last time, there are probably plenty more.
