Envirogel – Silica Gel (Orange to Green Indicating)

Envirogel’s orange indicating silica gel offers an ideal solution for applications where visual control of moisture is essential. As the gel adsorbs moisture, it gradually changes colour from orange to green, thereby providing a clear indication of when reactivation or replacement is necessary.

In the realm of arts and crafts, silica gel plays a vital role in preserving materials and maintaining optimal humidity levels. Moisture, if left unchecked, can damage delicate items such as paper, fabric, and dried flowers—causing them to degrade, wrinkle, or develop mold. To counter this, silica gel effectively adsorbs excess moisture, keeping materials dry and in excellent condition.

For example, when preserving pressed flowers or leaves, silica gel helps retain their colour and shape over time. Similarly, in jewellery making, it prevents tarnishing of metal components and protects beads, gemstones, and other materials from humidity related damage.

Furthermore, artists frequently use silica gel in storage containers to safeguard paintings, sketches, and other artwork from moisture issues. Thanks to its colour-changing feature—from orange to green—it offers a simple yet effective way for crafters to monitor moisture levels. Additionally, its non-toxic and reusable nature makes it a safe, long term solution for moisture control in creative environments.

Silica gel operates efficiently at temperatures up to 60°C. However, it performs best at room temperature (20–35°C) and in environments with high relative humidity (60–90% RH).
