Similar to Reactive Ice but with a lighter red halo. Great range of reactivity.
The "B" represent glass that falls outside the normal target range for Bullseye Glass. Often called "Curious" glass, it is still compatible and can be used just like normal "F" glass.
May React With Copper, Silver.
Cold Characteristics
Similar in appearance to Clear Transparent (001101) except it may include a slight tint of color (blue to green). Also similar to Reactive Ice Clear (001009).
Working Notes
Part of a series that includes Reactive Cloud Opal (000009) and Reactive Ice Clear. Be careful not to confuse this style with Clear Transparent or Reactive Ice Clear. Reactive combinations have the potential to create an interface color, which may continue to develop through multiple firings. Copper-based reactions tend to be variations of light to deep red, while silver-based reactions develop as earth tones. Reactions are generally related to the amount of copper and silver content, heat work and surface area contact.
Working characteristics are similar to Reactive Ice Clear, generally with a lighter red reactive palette. Some copper-bearing styles that react with Reactive Ice Clear do not readily react with Red Reactive Clear. Expect variation.
Categorized reactions based on a single full fuse with copper-bearing coarse frit (-0003)
No reaction: 001145, 001408, 001417, 001808
Light to medium reactions (variation): 001416, 001464, 000145, 000116
Medium to strong reactions: 001116, 000144, 000146, 000164, 000216, 001019-0031, -0051 (rainbow irid)
Strong reactions may permeate the iridized surface, finding greater surface contact through thinner sections of the irid coating (gold, silver) and minute fissures throughout. Crackle patterning is generally more open where the irid coating is thicker and transitions to dense coverage in thinner sections. Expect variation.
