You would like to glue wine corks together make a trivet. What work best. Does it need be heatproof?

When choosing a glue to adhere wine corks together for a trivet, it is important to consider the following factors:

1. Strength: The glue should be strong enough to hold the corks together securely, even when subjected to heat and pressure.

2. Heat Resistance: Since a trivet is intended to protect surfaces from hot pots and pans, the glue should be heat-resistant to prevent it from melting or losing its bond when exposed to high temperatures.

3. Flexibility: The glue should have some flexibility to accommodate any expansion or contraction of the corks due to temperature changes.

Based on these factors, the best type of glue for gluing wine corks together for a trivet is:

1. Epoxy Glue: Epoxy glue is known for its superior bonding strength and heat resistance. It creates a strong, durable bond that can withstand high temperatures. Epoxy glue is also waterproof, making it suitable for use in a kitchen environment.

2. High-Temperature Silicone Adhesive: High-temperature silicone adhesives are specifically formulated to withstand extreme heat. They are commonly used for applications such as bonding gaskets and seals in high-heat environments. This type of adhesive provides excellent adhesion to cork and can tolerate high temperatures generated by hot pots and pans.

It's important to follow the manufacturer's instructions for using either of these glues, including proper surface preparation, mixing ratios (for epoxy glue), and curing times, to ensure a strong and long-lasting bond.

To ensure the safety of your trivet, it is advisable to use corks that have been thoroughly cleaned and dried to remove any residual wine or moisture. Additionally, allow the glue to cure completely before using the trivet to ensure that it is securely bonded.
