Did you know that the internal surface area of a teaspoon of silica gel beads is equivalent to that of a football field? This amazing property makes silica gel a relatively low-cost method for protecting collections on display and in storage from inappropriate or fluctuating environments. But not all silica gel is created equal.
- Are you curious as to why silica from preservation vendors is more expensive than other desiccants or gel from commercial vendors?
- Have you found loose silica beads or cartridges and pondered why it no longer seems to be “working”?
- Interested in guidance on how much to use for your application?
Whether it comes in sachets, cartridges or loose beads, the manner in which it is installed and cared for will greatly affect its efficacy. This webinar will focus on understanding the different types of gel, why it matters which you use, and how to calculate appropriate amounts for use in a vitrine or storage cabinet. The basics of appropriate preservation environments, creating a safe microclimate and how to monitor the environment within will be touched on.
