Topic tags/keywords: glue glue selection heat resistant glue trivet cork trivet

I am near the end of one of the projects I’m making as a Christmas gift, but just want to make sure I use the most appropriate glue for the job.

The project in question is a cork trivet. I’ve got a chunk of maple that I hogged the center out of in order to glue the corks down. I am wondering what the best glue to use for this might be? Preferably waterproof (like TBIII or Gorilla Glue), as well as heat tolerant/resistant since there will be hot pots and dishes sitting on top of the corks. I have cut the corks about half way through, lengthwise so that I have a nice glue-up surface.

I have also thought about using clear silicone caulk, as I like the fact that it’ll dry clear (compared to TBIII and the regular Gorilla glue that I have on-hand) and the silicone is obviously watertight.

I’m trying to think long term here as far as heat-up and cool-down cycles. I could be very well be putting too much thought into this, but I figure I might as well ask, rather than risk using the wrong product for the job.

Anybody have any solid input on the subject? Thanks in advance!

I have read about this at one time but I am not going to try to relocate the article I read. If my memory is correct (sometimes not a good assumption) I seem to recall that TB-III was identified as being more heat resistant than others.

Go for the silicone.
There are many high temp versions made by Dow – there is a 6 page brochure at the link.
The DOW 736 is red in color but used in commercial ovens it is good from -85 to +500 F. There are several other grades and colors.
I would figure nothing you put on the trivet would cause your glue temp to exceed ~350 or so. These days all the muffin and bread pans are just flexible silicone so food safe and high temps are not problems, but there are a number of grades.
Also it is easy to cut the silicone with an xacto knife and replace any burned/stained cork without fighting to remove the old glue.
As I understand, the DOW 736 is what they use to glue/seal the glass window into the door or your oven – but I cannot guarantee that is the case.

Use ” liquid Nails” to attach cork to wood. No prpblem with heat or moisture.

I’m guessing nothing hotter than 350-degrees will be placed on this trivet. And, since heat rises, that’ll help too.

This is honestly more of a commemorative piece from a family trip, so I don’t know if it’ll see a lot of use or not? I hope it does.

Thanks for the info. so far guys. If anyone else wants to chime in, please do so. I have another day or two to decide.

I don’t think heat will be an issue, the cork will insulate it well enough. Of course you could just rest the cork inside a trivet sized mortise and not use glue at all, this would make maintenance or replacement of the cork much easier and then there is no moisture/heat resistance glue to worry about…just another way of looking at it.
