Dammar Gum Resin Crystals

Natural Dammar gum resin crystals obtained from Shorea trees in Indonesia (Sumatra).
White to yellowish-white translucent, globular to pear-shaped grains, irregular fragments or stalactite masses. Grade A consists of 1/2 cm to 5 cm pieces as well as about 5% resin powder. 
Used in incense, varnish and other products. Commonly used in oil painting, both during the painting process and after the painting is finished. Dammar crystals are also dissolved in molten paraffin wax to make batik, to prevent the wax from cracking when it is drawn onto silk or rayon.
Damar crystals are dissolved into beeswax with pigment added to harden it in order to make encaustic paints.
Dammar resins were often used in the past to caulk ships, frequently together with pitch or bitumen.

Minimum-Maximum Thermometer with Hygrometer – Vintage Brass Finish

This analog climate monitoring instrument is designed for simultaneous tracking of current, maximum, and minimum temperatures along with relative humidity. The device incorporates a bimetallic strip mechanism for temperature measurement. As ambient temperature changes, the main indicator hand (black) moves accordingly, mechanically pushing the secondary red and blue markers to record the highest and lowest temperatures reached. The red hand indicates the daily maximum, while the blue hand captures the daily minimum. These markers are reset manually via two independent knurled metallic knobs mounted on the dome—bottom knob resets maximum, top knob resets minimum. The hygrometer continuously displays current relative humidity as a dial reading. This unit is wall-mountable via an integrated rear keyhole slot, requires no electrical power, and is suitable for environments where continuous monitoring of climate variability is necessary.

Product Specifications

Applications and Benefits:

• Records and displays daily maximum and minimum temperatures
• Continuously monitors ambient humidity with built-in hygrometer
• Provides analog readout ideal for off-grid or power-sensitive environments
• Mechanical reset enables daily climate logging without digital interfaces
• Suitable for greenhouses, indoor climate control studies, and environmental labs

Caution:

Reset maximum and minimum indicators daily using the provided knobs to ensure accurate tracking. Do not submerge or expose the unit to excessive moisture or corrosive chemicals, as this may affect sensor performance and cosmetic finish.
