Bullseye Glastac Fusing Glue

Glastac. This may be a repeat of an earlier gripe. I just am unable to get this product to work. For me, using it as I believe I should, it has no tack at all. Now I am fairly new to warm glass work and therefore happy to learn. A small applicator bottle, small drops, allow to dry should secure for movement, the glass for my 2 layer project. No, just doesn't do it. It works for others why not me?

WARM GLASS REPLY: Hi Peter, Glastac is best used to lightly hold small elements in place for moving to your kiln (which it will do while still wet). It is not really intended for a strong or permanent hold. The benefit is its workability because it stays wet for a long time and does not stick to your fingers like PVA, it also burns out more cleanly.

Fabulous product. Ideal for large pieces as it allows time to make design adjustments if required and there is no residue left after firing. Although I have not had issues with movement (ie " slipping") mentioned by other reviewers, I generally use galastic gel for jewellery and other small items.

This simply does not work! I gave it the benefit of the doubt and tried it several times but, honestly, you may as well apply water! It does not glue glass to glass. Not only was it a complete waste of money but it also ruined valuable dichroic glass because as it didn't secure the glass pieces together, they moved off the glass while fusing. I even gave it several hours to set but it never did.

Warm Glass Response: We are sorry to hear your feedback, Glastac is intentionally a very thin glue which if applied to the corners of a piece works as intended, if a piece is flooded, the glue will not dry and will then boil in the fusing process, causing the pieces to move apart. For a thicker glue, use Glastac Gel.

The invention of Glastac Gel Glue was the saving of my sanity. I find using it calms me. It is thicker and pieces tend to stay mostly put where I set them down one on top of another. Using this thinner glue for years to make kiln fused jewellery, between glass layers to hold it together while firing was like trying to glue two ice blocks together with water, and it was far slower to dry than the gel. Either way, both the small bottles last me for ages as all I need are the tiniest drops of glue.

I find Glastac (pink one) really efficient in keeping frit in place especially if I'm using the frit quite thickly for example to form a heart on a coaster. Spread a small amount of Glasstac just to keep the frit in place as you add it then when you are happy with your design add a few drops especially around the edge of the area of frit and let it dry overnight. You can then move it to the kiln without any mishaps.
